EPM9560RZ208-15 - MAX 9000 EPLD, 560 Logic Elements | Altera
The Altera (Intel) EPM9560RZ208-15 is a member of the MAX 9000 EPLD family, providing 560 macrocells (approximately 12,000 usable gates) in a 208-pin PowerQuad QFP (RQFP) package with -15 speed grade (15 ns pin-to-pin delay). It is built on a 0.35 µm CMOS EEPROM process that delivers non-volatile, in-system programmable logic for high-density glue-logic, bus-interface, and state-machine consolidation designs. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the architectural simplicity of PAL/GAL with multi-macrocell arrays, in-system programmability via IEEE 1149.1 JTAG, and predictable timing. In the broader taxonomy, an EPLD is a sub-class of CPLD (Complex Programmable Logic Device), which itself sits between discrete PLDs and high-density FPGAs. MAX 9000 sits near the upper end of the CPLD density envelope offered in the late-1990s/early-2000s Altera portfolio, providing high I/O counts and predictable timing suitable for board-level glue logic. Key features include 560 macrocells, 16 logic array blocks (LABs), 212 user I/O pins, 5V tolerant I/O on selected variants, in-system programmability (ISP) through JTAG, and a maximum toggle frequency of 100 MHz. The FastTrack interconnect provides continuous routing that yields fully deterministic, hazard-free timing — every path through the device has a guaranteed propagation delay independent of logic placement. Designers can therefore budget timing without floorplanning iterations. The RQFP-208 package offers 208 pins with low profile suitable for socketed and surface-mount designs. With 212 user I/Os available in the package and high-drive capability on outputs, the EPM9560RZ208-15 is well suited for parallel bus interfaces, address decoding, memory control, and peripheral multiplexing tasks where multiple discrete 74-series devices would otherwise be required. The -15 speed grade delivers tPD = 15 ns, suiting 33 MHz synchronous designs. Typical applications include legacy industrial control systems, telecommunications backplane glue logic, ISA/PCI bus address decoding, and microcontroller peripheral expansion. The wide I/O count and predictable timing also suit it for ASIC prototyping in designs that later migrate to structured ASIC or gate-array devices. When designing with the EPM9560RZ208-15, note that the device is a mature part approaching end-of-life. Designers of new products should consider the Altera (Intel) MAX V, MAX II, or MAX 10 CPLD families, which offer lower power, smaller packages, and modern I/O standards. For legacy board replacement, verify pin compatibility with the original design footprint and review the datasheet's DC characteristics, particularly VCCIO banks and 5V tolerance. This page synthesizes distributor pricing, drop-in alternatives from the MAX 9000 family, and practical design notes not consolidated in the manufacturer datasheet — giving sourcing engineers a single reference for both qualification and substitution decisions.
EPM9560SRC208-7 - MAX 9000 EPLD, 12k Gates, 208-Pin SQFP | Altera
The Altera EPM9560SRC208-7 is a member of the MAX 9000 family of high-density Erasable Programmable Logic Devices (EPLDs) providing 12,000 usable gates in a 208-pin SQFP (Surface-mount Quad Flat Pack) package. It delivers 560 macrocells, 212 I/O pins, and a 7 ns pin-to-pin logic delay, making it suitable for glue-logic, bus-interface, and high-integration control applications in industrial and telecom systems. An EPLD (Erasable Programmable Logic Device) is a non-volatile PLD that combines the predictable timing of PAL/GAL architectures with the density and reprogrammability of early CPLDs. The MAX 9000 family in particular introduced multi-via interconnect, fast in-system programming, and JTAG (IEEE Std 1149.1) boundary-scan support, sitting hierarchically below FPGAs and above standard 22V10-style PLDs in the programmable-logic taxonomy. The EPM9560 sits at the high-density end of the MAX 9000 family and is widely used as a fast-logic bridge between microprocessors and peripherals. Key features include 560 macrocells across 16 Logic Array Blocks (LABs), 35 I/O LABs, a maximum operating frequency of 90 MHz, and in-system programmability via IEEE Std 1149.1 JTAG. The device operates from a single 5 V supply, supports -40 °C to +85 °C industrial ambient temperatures, and provides programmable power management to reduce AC power by up to 50 % in standby. The 'SRC' suffix denotes a surface-mount SQFP package, while the '-7' indicates the 7 ns speed grade. Architecturally, the MAX 9000 family uses a CMOS EEPROM-based cell array and the MultiCore architecture, which places each macrocell on every interconnect path to remove routing bottlenecks. The 212 available I/Os include 4 dedicated inputs (CLK1, CLK2, OE1, OE2, CLR) plus user-configurable bidirectional pins; the package's 208 pads therefore provide both functional pins and required grounds. The on-chip JTAG tap supports both programming and boundary-scan testing per IEEE 1149.1. Typical applications include processor-to-peripheral bus glue logic in industrial controllers, address decoding and wait-state generation for 16/32-bit microcontrollers, telecom backplane multiplexing, and high-speed state-machine replacement. Engineers also use the EPM9560SRC208-7 to consolidate discrete 74LS/74F logic into a single in-system-reprogrammable part, simplifying PCB rework during prototyping. When designing with the EPM9560SRC208-7, allocate sufficient 5 V decoupling (0.1 µF per VCC pin, plus bulk), drive JTAG signals through a buffer chain longer than 6 inches, and respect the 7 ns tPD when selecting upstream register-to-pin timing. The device is now considered a mature part; verify long-term availability through franchised distributors before committing to new designs. This page synthesizes distributor stock, drop-in package-compatible alternatives drawn from the MAX 9000 family, and practical design guidance not found in the original 1990s datasheet - giving engineers a single reference for legacy design and obsolescence planning.

The Intel / Altera EPM9560SRC240-15 is a member of the MAX 9000 family of Complex Programmable Logic Devices (CPLDs) housed in a 240-pin Surface-Mount RQFP package. It provides 560 usable gates, 16 logic array blocks, and a 15 ns maximum pin-to-pin logic delay, making it suitable for high-density glue-logic, bus-interface, and state-machine designs that were typical in late-1990s and early-2000s telecom and industrial systems. A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic device that combines multiple PAL/GAL-like macrocells on a single die with an interconnect fabric. The MAX 9000 family sits in the broader taxonomy: programmable logic device (PLD) -> CPLD -> EPLD/CPLD -> high-density programmable logic. CPLDs are characterized by deterministic timing, predictable I/O placement, and zero-configuration EEPROM or EPROM cells, distinguishing them from SRAM-based FPGAs which require a separate boot PROM. Key specifications of the EPM9560SRC240-15 include 560 usable gates, 16 Logic Array Blocks (LABs), 212 macrocells, and a maximum operating frequency (fMAX) consistent with the 15 ns tPD speed grade. The device operates from a single 5 V supply and is offered in the 240-pin surface-mount RQFP (S-prefix) package, with the RC240 variants being the pin-compatible ceramic PGA/quad equivalents in the same family. Architecturally, the EPM9560 uses Altera's classic MAX (Multiple Array matriX) architecture with a global interconnect that routes signals between LABs. Each LAB contains 16 macrocells with individual product-term allocation, and the device is in-system programmable (ISP) via a JTAG/IEEE 1149.1 boundary-scan interface. The -15 speed grade denotes 15 ns maximum pin-to-pin delay, making it suitable for 66 MHz-class system bus applications. Typical applications include 5V glue-logic consolidation, address decoding and bus-interface bridging, peripheral controller replacement (replacing dozens of 74LS/74F TTL devices), industrial control state machines, and telecom backplane glue logic. The instant-on, non-volatile nature of MAX 9000 makes it preferable to SRAM FPGAs in deterministic-startup applications such as military/aerospace and industrial control. When designing with the EPM9560SRC240-15, note that the device is a legacy mature part. Lead-time and lifecycle status must be verified before new designs, as the part is approaching or has entered NRND/EOL status with major distributors. The S-prefix denotes the surface-mount RQFP variant, while the RC-prefix denotes the pin-compatible ceramic-quad variant. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes not found in the manufacturer datasheet. The EPM9560SRC240-15 belongs to the EPM9560 family, with speed grades -10, -12, -15, and -20 and package options including RQFP-208, RQFP-240, and PGA-280.

Built on Altera's third-generation Multiple Array MatriX (MAX) architecture, this device delivers 12,000 usable gates with in-system programmability (ISP) through the IEEE Std. 1149.1 JTAG interface, eliminating the need for a separate programmer. A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL/GAL-like macrocell arrays on a single die with a programmable interconnect matrix. CPLDs sit in the broader taxonomy of programmable logic devices (PLDs) alongside FPGAs, but are typically used for glue logic, bus interfacing, state-machine control, and fast deterministic I/O rather than large parallel data processing. The MAX 9000 architecture extends the MAX 5000/7000 lineage with enhanced macrocell density, JTAG-ISP support, and 5V-tolerant I/O, making EPM9560 devices appropriate for industrial, telecom, and embedded control subsystems. Key features of the EPM9560TC208-20 include 560 macrocells, 12,000 usable gates, 149 user I/O pins (per family datasheet), and a 20 ns pin-to-pin propagation delay (commercial grade, -20 speed grade). The device operates from a 5V core supply with MultiVolt I/O supporting 3.3V and 5V interface levels. Programmable interconnect is achieved through the continuous FastTrack interconnect array, and non-volatile EEPROM cells store configuration without external memory. The TQFP-208 package (JEDEC S-PQFP-G208) provides a 0.5 mm pitch surface-mount footprint compatible with standard PCB assembly and reflow processes. The EPM9560TC208-20 is supported by Altera MAX+PLUS II and Quartus development tools, which provide VHDL/Verilog synthesis, timing simulation, and JTAG programming via the ByteBlaster or MasterBlaster download cables. Configuration is loaded through the built-in JTAG port, supporting both in-system programming during board bring-up and field firmware updates. Typical applications include industrial control glue logic, telecom bus interfacing, address decoding for microprocessor systems, PCI bus interface bridging, and state-machine controllers in embedded designs. Designers should budget adequate ground and 5V decoupling near the package, observe JTAG chain integrity for ISP, and verify that the chosen I/O standard matches downstream ASIC/FPGA logic levels before final routing.
EPM9560WC208 - 560 Macrocell EE PLD MAX 9000 | Altera | CQFP-208
The Altera EPM9560WC208 is a 560-macrocell electrically erasable programmable logic device (EE PLD) from the MAX 9000 family, packaged in a 208-pin ceramic quad flat pack (CQFP-208) with 0.50 mm terminal pitch. It operates from 3.3 V or 5 V rails, supports a maximum clock frequency of approximately 117.6 MHz, and provides up to 149 user-configurable I/O lines for high-density glue-logic and state-machine integration. The device uses a CMOS EE process that retains configuration in non-volatile cells, allowing instant-on behaviour without an external boot PROM. The MAX 9000 family is a high-density complex programmable logic device (CPLD) lineage positioned between classic PAL/GAL arrays and modern FPGAs. It integrates multiple logic array blocks (LABs) with a programmable interconnect matrix (PIA), giving engineers thousands of usable flip-flops (the EPM9560 series reaches 772 flip-flops) on a single die. Designers choose this category when deterministic pin-to-pin timing, instant-on non-volatile configuration, and 5 V tolerance are all required - conditions that mainstream SRAM-based FPGAs cannot meet without external supervision. Key features of the EPM9560WC208 include 560 macrocells across 35 LABs, 772 dedicated flip-flops, 16.6 ns pin-to-pin propagation delay in the -15 speed grade, in-system programmability via IEEE 1149.1 JTAG, and built-in hot-socketing support that allows the device to be inserted into a powered backplane without latch-up. The CQFP-208 ceramic package is a ruggedized form factor that historically served military, aerospace, and down-hole telemetry applications where plastic packages are unsuitable. The architecture is built on a CMOS electrically erasable process; configuration EEPROM cells hold the pattern even when power is removed, eliminating the boot PROM required by SRAM FPGAs. With 149 I/O pins distributed across 5 V-tolerant banks, the EPM9560WC208 can bridge multiple logic domains on the same board, including 3.3 V microcontrollers, 5 V peripheral buses, and TTL peripherals, simplifying mixed-voltage glue logic. Typical applications include military and aerospace avionics, industrial motor control, telecom backplane bridging, legacy bus protocol conversion (VME, PCI), and replacement of multiple discrete PAL/GAL devices. Engineers select the EPM9560WC208 when the design needs the instant-on behaviour of non-volatile EE memory combined with the timing predictability of a MAX-family CPLD. When designing with this part, ensure that the JTAG chain is correctly ordered and that the ceramic CQFP-208 package is matched to a socket or PCB land pattern rated for ceramic body dimensions. Note that Altera has issued a Product Discontinuance Notice (PDN) for selected MAX 9000 ordering codes, so designers should verify lifecycle status and consider migrating to the EPM9560 in the 208-pin RQFP plastic package for new designs. This page synthesizes distributor availability, drop-in alternatives, lifecycle status, and practical design notes not found in the manufacturer datasheet.
EPM9560WC208-15 - 560-Macrocell EE PLD, 117.6 MHz | Altera
The Altera EPM9560WC208-15 is a member of the MAX 9000 family of electrically-erasable programmable logic devices (EE PLDs) from the legacy Altera MAX architecture, delivering 560 macrocells, 35 Logic Array Blocks (LABs), and 772 flip-flops in a 208-pin Ceramic Quad Flat Pack (CQFP-208) package with 0.50 mm terminal pitch. It features a maximum clock frequency of 117.6 MHz and a propagation delay of 16.6 ns (commercial speed grade -15), supplied in a CMOS process supporting 3.3 V or 5.0 V configurable I/O operation. A Programmable Logic Device (PLD) is a digital integrated circuit whose logic function is defined by the user after manufacture, sitting in the broader hierarchy: PLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. The MAX 9000 series pioneered high-density EE PLDs using EEPROM configuration cells, allowing in-system reprogrammability without an external configuration memory. This places the EPM9560 in a distinct class between simple PAL/GAL devices and full FPGAs, offering predictable timing, deterministic pin-to-pin delays, and high usable-gate counts. Key differentiating specifications include 560 macrocells (the largest in the MAX 9000 family), 149 usable user I/O pins (3.3 V/5 V tolerant), 35 LABs providing structured logic fabric, and 117.6 MHz maximum internal frequency. The 208-pin CQFP package provides hermetic ceramic packaging suited for harsh thermal and mechanical environments, with a 0.50 mm pitch suitable for surface mounting on standard PCB land patterns. Programming is performed via the JTAG-compliant IEEE Std 1149.1 boundary-scan interface using the Altera MAX+PLUS II or Quartus development toolchains. Typical applications include industrial control logic, telecom interface glue logic, MIL/Aerospace systems requiring hermetic ceramic packaging, military-grade replacement of discrete TTL/CMOS logic, and legacy 5 V system glue logic. The wide 3.3 V/5 V I/O compatibility simplifies migration from 5 V ASICs to programmable equivalents without level shifters. When designing with the EPM9560WC208-15, account for the ceramic CQFP package thermal behavior, which is markedly better than plastic QFP packages and well-suited for extended-temperature applications. Use the MAX+PLUS II baseline and fitter to verify pin assignments and timing closure before committing to the layout. Note that Altera has formally discontinued the 208-pin CQFP package and recommends the form-fit-function equivalent 208-pin RQFP variants for new designs.
EPM9560WC208-15C - 560-Macrocell EE PLD | Altera MAX 9000
The Altera EPM9560WC208-15C is a high-density Electrically Erasable Programmable Logic Device (EE PLD) from the MAX 9000 series, featuring 560 macrocells in a 208-pin Ceramic Quad Flat Pack (CQFP-208) with 0.50 mm terminal pitch. The device operates from a 3.3 V or 5 V supply, delivers a maximum clock frequency of 117.6 MHz, and offers a pin-to-pin propagation delay of 16.6 ns in the -15 speed grade. A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on logic fabric that combines multiple Programmable Logic Array (PLA)-style blocks with a centralized interconnect matrix. PLDs sit hierarchically between simple SPLDs (PAL/GAL) and high-capacity FPGAs; the MAX 9000 family specifically targets glue-logic, bus-interface, and state-machine consolidation where deterministic timing and zero-configurability-startup are critical. Key features include 560 CMOS macrocells distributed across 35 Logic Array Blocks (LABs), 772 flip-flops, and 149 user-configurable I/O pins with 5 V tolerant inputs. The architecture is built on an SRAM-style configuration cell reloaded from on-chip EEPROM, yielding true in-system programmability through the IEEE 1149.1 JTAG interface. A typical internal counter frequency of 117.6 MHz enables fast sequencer design, while the 16.6 ns tPD supports 60 MHz synchronous glue logic. The device is implemented in a 0.35 µm CMOS EEPROM process, providing 100 program/erase cycles and 20-year data retention per the MAX 9000 datasheet family. The I/O structure uses 3.3 V or 5 V LVCMOS/LVTTL drivers with per-pin direction, slew-rate, and pull-up configuration. MultiVolt I/O allows direct interfacing between 5 V and 3.3 V buses without external level shifters, simplifying mixed-voltage board design. Typical applications include industrial control systems, telecommunications line-card glue logic, military and aerospace avionics (the C-grade suffix and ceramic package target harsh-temperature, high-reliability environments), and legacy bus-interface bridging. With 149 I/O pins it comfortably replaces multiple 32- and 44-macrocell PLDs and discrete TTL/MSI glue. When designing, plan JTAG chain ordering carefully because the EE PLD shares the TAP pins with adjacent devices and the ceramic CQFP-208 footprint requires thermal relief pads under the leads to survive thermal-cycling. Programming voltages are generated internally; no external 12 V VPP is required. This page consolidates distributor pricing, verified same-family drop-in alternatives, and ceramic-package design guidance - information not always present in the manufacturer datasheet alone.
EPM9560WC208-20 - 560-Macrocell CPLD, 23.6ns, PQFP-208 | Intel/Altera
The Intel (formerly Altera) EPM9560WC208-20 is a high-density electrically-erasable programmable logic device (EPLD) from the MAX 9000 family, delivering 560 macrocells organized in 35 logic array blocks (LABs) in a 208-pin power quad flat pack (PQFP/RQFP) package. The device is a CMOS, in-system-programmable complex PLD with a maximum propagation delay of approximately 23.6 ns (the “-20” speed grade) and supports operation with both 3.3 V and 5 V I/O signaling for flexible mixed-voltage system design. A CPLD (Complex Programmable Logic Device) is a non-volatile reconfigurable digital IC built from an array of AND/OR macrocell structures backed by EEPROM or flash memory; it occupies the design hierarchy between simple PLDs (PAL/GAL) and FPGAs, providing deterministic timing, fast I/O response, and instant-on behavior without external boot memory. Within Altera’s MAX 9000 family the EPM9560 sits at the top of the 9000 series density range, with 149 usable I/O pins and a programmable interconnect that makes it well suited to bus decoding, address mapping, glue-logic and state-machine replacement in industrial and telecom systems. Key features of the EPM9560WC208-20 include 560 macrocells, 35 LABs, 149 user I/O pins, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan test (BST) interface, dual 3.3 V/5 V I/O capability, and a programmable register/feedback architecture. The “W” suffix designates the power PQFP package with enhanced thermal characteristics for high-density designs, and the “-20” designator indicates a 23.6 ns pin-to-pin logic delay suitable for systems clocked up to roughly 40 MHz on combinational paths. Architecturally the device uses an EEPROM-based macrocell with individually programmable product-term steering, D/T/JK flip-flops, and a global interconnect matrix that delivers predictable, deterministic timing independent of routing density. This makes timing closure straightforward for address decoding, interrupt steering, and synchronous state-machine designs where FPGAs would add unnecessary silicon cost and configuration overhead. Typical applications include high-density bus and address decoding in microprocessor/microcontroller systems, peripheral interface glue logic (e.g., PCI/ISA bus bridges), state-machine and sequencer replacement, industrial control logic, telecom backplane glue logic, and JTAG-driven system monitoring. The 149 I/O pins allow large pin-count designs to be consolidated into a single PLD. When designing with this device, always observe the maximum I/O count (149), respect the dual-voltage VCCIO/VCCINT power sequencing rules, and use the Quartus II or MAX+PLUS II toolchain for design entry, fitting, and JTAG programming. Decoupling caps (0.1 microfarad ceramic in parallel with 10 microfarad bulk) should be placed within 1 cm of each supply pin to maintain signal integrity during in-system programming cycles. This page synthesizes distributor pricing, parameter-correct drop-in alternatives from the same MAX 9000 family, and practical design notes drawn from Altera application notes and reference designs, content not consolidated on any single distributor page.
EPM9560WC208-20C - 560-Macrocell EE PLD, 20ns, CQFP-208 | Altera
The Altera EPM9560WC208-20C is a 560-macrocell Electrically Erasable Programmable Logic Device (EE PLD) from the MAX 9000 family, housed in a 208-pin Ceramic Quad Flat Pack (CQFP-208) package and rated at a 20 ns pin-to-pin propagation delay. This CMOS device integrates 35 Logic Array Blocks (LABs) and exposes 149 usable I/O lines, supporting both 3.3 V and 5 V signaling for flexible system interfacing. The part carries a commercial temperature grade (the trailing "C" suffix) and provides JTAG BST in-system programmability. What is a Programmable Logic Device (PLD)? A PLD is a generic term for an integrated circuit whose logic function is defined by the end user after manufacture, rather than being hard-wired by the foundry. EE PLDs add non-volatile, electrically erasable configuration memory so the design can be re-programmed thousands of times in-circuit. The MAX 9000 family belongs to the higher-density tier of complex PLDs (CPLDs), bridging between classic 22V10-style PLDs and modern FPGAs in the programmable-logic taxonomy: PLD -> CPLD -> MAX 9000 -> high-density EE PLD. Compared with FPGAs, MAX 9000 parts offer deterministic timing, instant-on non-volatile configuration, and high pin-to-pin drive strength, which is why they remain favored in glue-logic, bus-interface, and legacy industrial designs. Key features include 560 macrocells, 35 LABs, 149 user I/Os, 20 ns propagation delay, JTAG-based in-system programmability, and operation from a 3.3 V or 5 V supply. The architecture combines a global interconnect with per-macrocell registers, allowing both combinatorial and registered logic with predictable timing. Configurable I/O standards enable mixed-voltage interfacing without external level shifters. Typical applications include legacy bus-interface glue logic in telecom and industrial backplanes, address decoding and wait-state generation in 5 V/3.3 V embedded systems, industrial control boards, and avionics/military systems that rely on the ceramic CQFP package for thermal and reliability robustness. The 208-pin ceramic package is selected where extended temperature, vibration tolerance, or hermeticity is required. When designing with this part, mind the 20 ns tPD: at a 33 MHz bus it offers zero wait-state decode, but at 50 MHz external latches become necessary. Decoupling should follow Altera's MAX 9000 reference design with one 0.1 uF ceramic per VCC/GND pair plus a 10 uF tantalum bulk cap. The device is mature and obsolete/last-time-buy at most distributors, so design teams should verify lifecycle and pinout against the original Altera datasheet before committing to new layouts. This page synthesizes distributor availability, parametric equivalents, and practical design notes not found in the manufacturer datasheet.

The Intel / Altera EPM9560WI208-20 is a high-density 560-cell Complex Programmable Logic Device (CPLD) from the MAX 9000 family, housed in a 208-pin Ceramic Quad Flat Pack (CQFP208) package with gull-wing leads. It provides 23.6ns pin-to-pin logic delay, 560 macrocells, 16 logic array blocks, and up to 212 user I/O pins for complex glue-logic, bus-interface, and state-machine designs. The device is built on a 0.35-micron CMOS EEPROM process and is rated for industrial temperature operation. A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix. In the broader taxonomy it sits under programmable logic -> PLD -> CPLD -> MAX 9000 series -> high-density glue logic. CPLDs are commonly deployed as deterministic, low-latency controllers alongside microprocessors, FPGAs, and ASICs, providing boot configuration, address decoding, bus arbitration, and custom I/O expansion with predictable timing and instant-on behavior from on-chip EEPROM. Key features of the EPM9560WI208-20 include 560 macrocells, 16 logic array blocks (LABs), 212 maximum user I/O pins, 23.6ns worst-case pin-to-pin propagation delay (tPD), a JTAG-based IEEE 1149.1 boundary-scan interface, and in-system programmability via JTAG. The internal EEPROM configuration cells allow instant-on operation at power-up without external boot memory, and the device is supported by the Altera MAX+PLUS II and Quartus design tools. The MAX 9000 architecture splits the device into LABs connected by a programmable interconnect array (PIA). Each macrocell contains a programmable-AND/OR array, a flip-flop, and product-term steering, which gives the part deterministic 23.6ns timing across all paths. The 560-cell capacity places this device in the upper tier of the MAX 9000 family, suitable for designs that exceed the density of the MAX 7000 family but do not require an FPGA. Typical applications include military and aerospace avionics, industrial process control, telecommunication line cards, and legacy bus-bridge designs. The ceramic CQFP-208 package is preferred in harsh-environment and high-reliability systems where plastic packages are not acceptable, including down-hole, military, and aerospace programs. When designing with the EPM9560WI208-20, note that the -20 speed grade reflects 23.6ns tPD; faster -15 and -10 grades are available in the same MAX 9000 family for tighter timing budgets. Because this part is in the Ceramic QFP package with gull-wing leads, PCB layout must accommodate the larger pad geometry and inspect for lead coplanarity during assembly. This page synthesizes distributor pricing, drop-in same-family alternatives, application guidance, and comparison data not aggregated in a single location on the Altera / Intel datasheet.
GAL22V10D-15LPNI - 15ns 10-Macrocell E2CMOS PLD DIP-24 | Lattice
The Lattice Semiconductor GAL22V10D-15LPNI is a high-performance, electrically erasable CMOS Programmable Logic Device (PLD) in the industry-standard 22V10 architecture, packaged in a 24-pin PDIP (300-mil, through-hole DIP). It features 10 Output Logic Macrocells (OLMCs), a 15 ns maximum propagation delay, and an internal timing margin equivalent to roughly 83.3 MHz f_max, making it the highest-performance member of the GAL22V10 family. A PLD (Programmable Logic Device) is a digital integrated circuit whose logic function and interconnects are defined by the user after manufacture. Within the IC taxonomy, PLDs sit between fixed-function logic gates and full FPGAs: a PLD implements combinational and registered logic via a programmable AND/OR array with dedicated output macrocells, whereas an FPGA uses distributed look-up tables, block RAM and soft cores. The "22V10" naming convention means 22 inputs (12 dedicated + 10 feedback) feeding 10 macrocells with variable drive polarity — this generic footprint is supported across multiple vendors, including Lattice, Atmel/Microchip and AMD, giving designers drop-in second sources. Key features of the GAL22V10D-15LPNI include 10 ns / 15 ns propagation delay grades, electrically erasable (E2CMOS) technology allowing 100+ reprogram cycles, in-system programmable architecture, a built-in security bit to lock the pattern, and low CMOS standby current with TTL-compatible I/O. The device is functionally and parametric compatible with standard bipolar and CMOS 22V10 devices, including the classic PAL22V10. The GAL22V10D combines a high-performance CMOS process with Electrically Erasable (E2) floating gate technology. The 10 OLMCs are individually configurable as registered, combinatorial, or I/O with selectable output polarity, and feedback paths allow buried state machines. Unlike UV-erasable EPROM-based 22V10s, the E2CMOS cell can be erased electrically in-circuit, which simplifies prototyping and field upgrades. Typical applications include address decoding and glue logic for microprocessor systems, state-machine and sequencer controllers, bus arbitration logic, peripheral interface adapters, and industrial control replacements of legacy bipolar PALs. Through-hole PDIP packaging suits legacy boards, test fixtures, and aerospace/industrial designs where DIP is preferred over surface mount. When designing, remember the GAL22V10D-15LPNI requires a single 5 V supply (VCC = 4.75 V to 5.25 V) and the JEDEC-standard 22V10 fuse map. Use a Lattice-approved programmer (e.g., ispGAL22V10-compatible) to load the pattern; the security bit, once programmed, prevents readback of the device. This page synthesizes distributor stock data, parametric alternatives, and practical design guidance not aggregated on any single manufacturer or distributor page, giving engineers a single reference for sourcing and second-sourcing the GAL22V10D-15LPNI.
ICE40HX4K-TQ144 - 3520-LUT 1.2V FPGA | Lattice Semiconductor
The Lattice Semiconductor ICE40HX4K-TQ144 is an ultra-low-power HX-series field-programmable gate array (FPGA) with 3,520 logic cells, 107 I/Os, 81,920 bits of configuration memory, and a 144-pin TQFP package. It operates from a 1.2 V core supply according to the supplied distributor data. The device targets compact, low-power programmable logic systems where FPGA flexibility is needed without the power and board complexity of a larger high-performance FPGA. A field-programmable gate array is a configurable digital semiconductor that contains programmable logic blocks, routing resources, input/output blocks, and configuration memory. In the hierarchy, an FPGA is a programmable logic device, a digital IC, and a semiconductor. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA can be programmed after manufacture to implement parallel data paths, control logic, serial interfaces, and hardware signal processing. The ICE40HX4K provides 3,520 logic cells and 81,920 bits of configuration memory, as identified by DigiKey and Mouser search results. Its 107 I/Os provide substantial connectivity for external memory, sensors, communications, control signals, and general-purpose digital interfaces. The HX family is positioned by Lattice as a low-power, high-performance FPGA family, making the part suitable for embedded control, communication, instrumentation, and education platforms where low static power and fast programmable logic are important. The 144-pin TQFP package exposes the FPGA in a conventional surface-mount form factor suitable for automated assembly and multilayer PCB designs. The verified source snippets identify the package as 144-pin TQFP or 144-LQFP terminology; designers should confirm the exact mechanical drawing and pin names against the manufacturer datasheet before releasing a PCB footprint. The supplied data does not specify speed grade, temperature range, power consumption, pin names, memory architecture beyond configuration capacity, or I/O voltage limits. Typical uses include custom interface controllers, low-power sensor aggregation, digital signal conditioning, communications adapters, test fixtures, and FPGA-based education or prototyping boards. For a new design, use the manufacturer’s configuration toolchain and verify pin assignments, supported I/O standards, clocking resources, power rails, decoupling requirements, and programming interface compatibility. Because the supplied evidence confirms the family and capacity but not a complete electrical characterization, unsupported values should not be inferred from generic iCE40 family claims.
ISPLSI - Lattice In-System Programmable Logic Family | CPLD
The Lattice Semiconductor ISPLSI family is a series of high-density, in-system programmable CMOS Complex Programmable Logic Devices (CPLDs) introduced in the early 1990s. The flagship ispLSI 1016 device delivers 2000 PLD gates with 96 registers, 32 universal I/O pins, 4 dedicated inputs, and 3 dedicated clock inputs in a 44-pin package. The family spans multiple sub-series including ispLSI 1000, 2000, 2000E, 2000VE, 3000, 5000V, 8000, and 8000V with gate counts from 1K to 45K and macrocell counts from 32 to 480. A CPLD (Complex Programmable Logic Device) is a type of programmable logic that combines multiple PAL/GAL-like logic blocks on a single chip with a programmable interconnect network. In the broader taxonomy, CPLDs sit alongside FPGAs in the programmable logic category, but use non-volatile EEPROM or flash configuration memory and a deterministic AND-OR logic fabric. Unlike SRAM-based FPGAs, most ispLSI devices retain their configuration without external boot memory, enabling instant-on operation - an important advantage for glue logic, bus interfacing, and power-up deterministic state machine applications. The ispLSI family pioneered 5V in-system programmability (ISP) via a 4-wire JTAG-like interface, allowing devices to be re-programmed on a populated PCB without removing the chip. This eliminated the expensive UV-erase window and programmer sockets required by earlier EPLDs. The Global Routing Pool (GRP) provides complete, deterministic 100% connectivity between all logic blocks and I/O pins with predictable timing - critical for replacing discrete 74-series glue logic in industrial and telecom designs. The ispLSI 2000E sub-family extends the architecture to 32 to 128 macrocells with 1K to 4K gates, while the ispLSI 5000V series scales to 256 macrocells with 12K gates. The ispLSI 8000V reaches 480 macrocells and 45K gates. All members share the same Lattice development flow using ispLEVER or ispDesignEXPERT software. Typical applications include peripheral bus interfacing, address decoding, state-machine replacement of discrete logic, and TTL/CMOS logic consolidation. When designing with ispLSI devices, ensure the JTAG ISP pins (TMS, TCK, TDI, TDO) are accessible for in-system programming. Use Lattice's recommended decoupling (typically 0.1uF per VCC pin) and follow the GRP routing guidelines for predictable timing. Most ispLSI devices are now classified as mature or discontinued by Lattice, so designers should evaluate ispMACH 4000 or MachXO2/XO3 as modern replacements for new designs.
ISPLSI 1032-60LT - 128-Macrocell 5V CPLD, 60MHz, TQFP-100 | Lattice
The Lattice Semiconductor ISPLSI 1032-60LT is a high-density in-system programmable Complex Programmable Logic Device (CPLD) from the ispLSI 1000 family, delivering 6000 PLD gates, 128 macrocells, and 192 registers in a 100-pin TQFP surface-mount package. It operates from a single 4.75 V to 5.25 V supply and provides a maximum propagation delay of 20 ns (60 MHz fMAX). According to the Lattice ispLSI 1032 datasheet, the device integrates 64 universal I/O pins, eight dedicated input pins, four dedicated clock input pins, and a Global Routing Pool (GRP) that distributes signals across the chip with predictable, fixed delay. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits between simple SPLDs/PLAs and large FPGAs in the programmable-logic taxonomy (CPLD -> PLD -> programmable logic -> digital semiconductor). It uses a small-block, sum-of-products architecture with macrocells, making it ideal for implementing wide combinational and registered logic, glue logic, bus decoding, state machines, and address decoding. Unlike SRAM FPGAs, the ispLSI 1032 is non-volatile and in-system programmable via a standard 5-pin JTAG chain, so designs can be updated on production hardware without removing the device. Key features of the ISPLSI 1032-60LT include 32 logic elements (each containing 16 macrocells with associated I/O), 6000 gates of usable logic, 4 dedicated clock inputs feeding four global clock buffers, asynchronous clear and preset per register, JTAG/IEEE 1149.1 boundary-scan test support, and 5 V CMOS I/O with TTL-compatible thresholds. The GRP provides a deterministic, fixed interconnect delay regardless of placement, simplifying timing closure for registered and combinatorial logic. Typical applications include wide address decoding, bus interface glue logic, state-machine controllers, peripheral interface latching, fast counters, frequency and pulse-width measurement, and any design requiring non-volatile, deterministic-timing 5 V glue logic in industrial control, telecom backplane, and embedded processor bus systems. When designing with this device, ensure the 5 V supply is within the 4.75 V to 5.25 V range and that all I/O banks are referenced to a single 5 V rail. Decouple VCC with 0.1 uF and 10 uF capacitors close to the pins. Note that Lattice's own ispMACH 4000V is the recommended modern replacement family for new designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
ISPLSI1016E-125LT44 - 2K Gates, 64 Macrocells, 125 MHz CPLD | Lattice
The Lattice Semiconductor ISPLSI1016E-125LT44 is a 5 V in-system programmable high-density Complex Programmable Logic Device (CPLD) from the ispLSI 1000E family, delivering 2K usable gates, 64 macrocells, and 96 registers in a 44-pin TQFP (LT44) package. It achieves a pin-to-pin propagation delay (tPD) of 7.5 ns and a maximum operating frequency (fMAX) of 125 MHz, making it suitable for high-speed glue logic and bus-interface bridging in industrial and legacy embedded systems. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a central interconnect fabric. CPLDs sit alongside FPGAs in the programmable logic hierarchy, but are distinguished by their deterministic timing, instant-on non-volatile configuration (typically E2CMOS), and lower logic density. The ISPLSI 1000E family belongs to Lattice's first-generation ispMACH-era devices, designed for fast I/O decoding, state-machine replacement, and peripheral interfacing in 5 V systems. Key features of the ISPLSI1016E-125LT44 include 32 universal I/O pins, four dedicated input pins, three dedicated clock input pins, and one global output-enable input routed through a Global Routing Pool (GRP) that provides complete interconnectivity between all logic elements. The device supports 5 V in-system programmability (ISP) via IEEE 1149.1 boundary-scan, enabling firmware upgrades without removing the part from the board. Programmable interconnect and macrocell registers allow designers to replace multiple discrete TTL/CMOS packages with a single non-volatile device. The ispLSI 1016E architecture partitions logic into four Generic Logic Blocks (GLBs), each containing 16 macrocells, a 32-bit product-term array, and dedicated clock/reset/preset control. The GRP delivers 100% connectivity between GLBs and I/O cells with predictable, fixed delays that simplify static timing closure. An on-chip diagnostic TAP allows read-back of programmed state for in-system verification, a feature rare among 5 V CPLDs of this generation. Typical applications include industrial control glue logic, ISA/PCI bus address decoding, peripheral interfacing (UART, FIFO, bus controllers), 5 V legacy system upgrades, and state-machine replacement on 3.3 V-5 V mixed boards. Its 5 V tolerance and industrial temperature grade make it a long-life component for factory automation, instrumentation, and telecom backplane designs where newer 3.3 V-only CPLDs cannot be used directly. When designing with this part, note that the LT44 (TQFP-44) footprint differs from the 44-pin PLCC variant (LJ44). Verify pinout compatibility before PCB rework. Decoupling caps (0.1 uF plus 10 uF bulk) should be placed within 5 mm of each VCC pin, and unused I/O pins must be configured as outputs with defined logic levels to minimize quiescent current. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers source and integrate legacy ispLSI parts confidently.
LC4032B-5T44C - 32-Macrocell 400MHz CPLD | Lattice
The Lattice Semiconductor LC4032B-5T44C is a 3.3V, 2.5V, or 1.8V in-system-programmable SuperFAST high-density PLD with 32 macrocells, a maximum operating frequency of 400MHz, and a propagation delay of 2.5ns. It is supplied in a 48-pin TQFP package, making it suitable for compact systems that require reconfigurable glue logic, interface control, clock distribution, and protocol bridging. A complex programmable logic device, or CPLD, is a programmable logic device that combines nonvolatile configuration storage with a structured array of macrocells. In the hierarchy of programmable logic devices, a CPLD sits above simple programmable logic arrays and provides deterministic timing, repeated in-system programming, and logic capacity suitable for consolidating multiple small fixed-logic functions. The LC4032B family supports 32 macrocells and up to 80 product terms per output, according to the supplied manufacturer-family search result. The principal performance features are a 400MHz maximum operating frequency, 2.5ns propagation delay, support for as many as four global clock pins, and programmable clock-polarity control. The device can operate with 3.3V, 2.5V, or 1.8V supply rails, allowing integration into systems with mixed voltage requirements. Its in-system-programmable architecture supports configuration updates without removing the device from a circuit. The LC4032B implementation uses an electrically erasable programmable nonvolatile memory architecture for persistent configuration, avoiding external configuration PROM. Global clock resources support high-speed synchronous logic, while distributed product-term logic provides flexible combinational and registered functions. These resources are relevant in control-plane designs where a small FPGA may be excessive but fixed logic would be costly to revise. Typical uses include bus-interface decoding, display and keypad control, industrial control modules, peripheral glue logic, data acquisition systems, communications equipment, and FPGA or processor companion logic. The 48-pin TQFP provides a practical balance between routing access, thermal performance, and board-space requirements. Designers should verify the exact pin assignments, supported I/O standards, AC timing values, and configuration requirements against the manufacturer datasheet before layout. Decoupling, ground-plane continuity, clock routing, and unused-pin treatment are particularly important in high-speed CPLD designs, even when the logic function appears simple. This page combines verified device identity, family-level performance information, sourcing links, practical design guidance, and qualified comparison context that is not consolidated on a standard distributor listing.
LC4032B-5T44I - 32 Macrocell 5 ns CPLD | Lattice
The Lattice Semiconductor LC4032B-5T44I is an in-system-programmable complex programmable logic device with 32 macrocells, a 5 ns speed grade, and a 44-TQFP package. The verified distributor description identifies it as a SuperFAST high-density PLD supporting 3.3 V, 2.5 V, and 1.8 V operation. It combines programmable logic, nonvolatile configuration storage, and deterministic I/O in one device, making it suitable for compact control, interface, and signal-generation systems. The -5 suffix denotes the stated 5 ns speed grade, while -T44I identifies the 44-pin industrial-temperature ordering configuration. A CPLD is a user-programmable digital logic device that stores a logic configuration in nonvolatile memory. In the semiconductor hierarchy, a CPLD belongs to programmable logic devices and uses interconnected macrocells to implement Boolean and sequential functions. Compared with a software-driven processor, an LC4032B implementation can execute fixed logic immediately after configuration, while compared with a small FPGA it is organized around a simpler macrocell architecture suited to compact glue logic. The verified LC4032B data identifies 32 macrocells, 5 ns timing, and a 44-TQFP package as the principal selection parameters. The family description also supports 3.3 V, 2.5 V, and 1.8 V operating environments. In-system programmability permits a design to be configured or updated through its programming path without removing the package from production equipment, provided the board meets the device's stated electrical and pin requirements. Typical uses include industrial control interfaces, peripheral bus decoding, data acquisition front ends, programmable instrument logic, communication-interface conditioning, and embedded control functions. Its fixed nonvolatile configuration supports repeatable startup behavior because no firmware-driven configuration sequence is required for established logic. Design work should begin with the manufacturer datasheet because macrocell capacity, dedicated pins, supported I/O standards, timing, power behavior, and programming requirements are not completely characterized by the provided search results. Confirm that every external signal, supply rail, pull state, and programming connection matches the exact datasheet before releasing a PCB. This page consolidates the verified distributor identification, available source links, package details, and engineering-selection context. It also distinguishes confirmed facts from missing specifications so procurement and design teams can assess fit without relying on unsupported inferred values.
LC4032B-5T48C - 32-Macrocell 400 MHz CPLD | Lattice
The Lattice Semiconductor LC4032B-5T48C is an ispMACH 4000B complex programmable logic device with 32 macrocells, a maximum operating frequency of 400 MHz, and a 2.5 ns propagation delay. It is supplied in a 48-pin TQFP package and supports in-system programmable SuperFAST high-density PLD applications. The verified device description also identifies the family as a blend of the ispLSI 2000 and ispMACH 4A architectures, combining programmable logic density with high-speed operation. An ispMACH 4000B CPLD is a programmable logic device in the broader semiconductor hierarchy of complex programmable logic devices, field-programmable logic arrays, and programmable digital logic. It is used when a design requires deterministic programmable logic, system-level integration, and in-system programming rather than a fixed application-specific standard product. The LC4032B-5T48C is appropriate for control logic, interface logic, signal conditioning, glue logic, and embedded control functions that require more integration than a simple programmable logic array while retaining flexible field programmability. Key verified features include 32 macrocells, a 400 MHz maximum operating frequency, and 2.5 ns propagation delay. The family description states that the device is a 3.3 V, 2.5 V, and 1.8 V in-system programmable SuperFAST high-density PLD. The product search data also identifies the device as the ispMACH 4032B 2.5 V version. The combination of programmable logic density and high maximum frequency supports compact designs that need fast combinational and sequential logic while preserving post-assembly programmability. The device belongs to the Lattice ispMACH 4000 family, which combines two established Lattice architectures according to the retrieved product description. This architecture can be useful for designs that need programmable pin assignment, logic implementation, timing control, and system integration. Designers should evaluate the complete TQFP pinout, power rails, clocking, I/O standards, and timing requirements against the manufacturer datasheet before finalizing a PCB or production configuration. Typical applications include industrial control and automation, embedded interface logic, communication equipment, test and measurement systems, and general-purpose digital control. Its 400 MHz maximum operating frequency is relevant to control-path and data-path blocks, while its 32 macrocells provide a moderate logic capacity for consolidating multiple fixed-logic functions into one programmable device. The LC4032B-5T48C can reduce discrete logic count when the design is stable enough to implement in a CPLD. When designing with the LC4032B-5T48C, verify the exact TQFP pin assignment, supply requirements, I/O compatibility, and programming configuration from the official manufacturer documentation. The verified search results provide a genuine manufacturer-linked datasheet reference and distributor listings, but they do not provide a complete verified pin table or current unit-price values. Those details must therefore be confirmed before release to manufacturing or use in a live procurement decision. This product data page combines verified source links, manufacturer-family positioning, identified electrical highlights, package information, and engineering-oriented design guidance. It also distinguishes confirmed information from fields that require direct datasheet review, helping engineers evaluate the LC4032B-5T48C for high-speed programmable-logic designs without treating unverified assumptions as specifications.
LC4032B-5T48I - 400MHz 32-Macrocell CPLD | Lattice
The Lattice Semiconductor LC4032B-5T48I is an in-system-programmable, SuperFAST high-density PLD with 32 macrocells, a maximum operating frequency of 400 MHz, and a 2.5 ns propagation delay. It is offered in a 48-lead TQFP package and supports 3.3 V, 2.5 V, and 1.8 V operation, making it suited to compact, high-speed control and interface logic. A complex programmable logic device, or CPLD, is a programmable digital integrated circuit that combines nonvolatile logic storage, configurable macrocells, and programmable interconnect resources. A CPLD occupies the hierarchy between basic programmable array logic and more complex programmable systems. Its electrically erasable configuration allows a finished PCB to be programmed or reprogrammed without replacing the device. The LC4032B family is positioned for fast deterministic logic. Verified source data identifies up to four global clock pins, programmable clock-polarity control, and as many as 80 product terms per output. These features allow multiple clock domains, registered control logic, bus arbitration, address decoding, and interface bridging to be consolidated in one configurable device. In-system programmability also supports production programming, field upgrades, and design revisions after PCB assembly. The -5 speed designation corresponds to the verified maximum frequency of 400 MHz and propagation delay of 2.5 ns. The industrial suffix identifies the ordering variant, but exact junction-temperature limits, current consumption, and absolute maximum ratings were not included in the supplied verified records and are therefore not inferred here. Designers should use the manufacturer datasheet for timing constraints, pin states, power-up behavior, AC/DC limits, and programming requirements before release to production. Typical uses include industrial control, communication interfaces, test equipment, data acquisition, peripheral control, and compact high-speed logic blocks. At 32 macrocells, the device is most appropriate for moderate-density designs where deterministic timing, simple integration, and in-system reconfiguration are more valuable than the routing capacity and register resources of a large FPGA. The primary design consideration is timing closure. External interfaces should be assigned to pins with compatible standards, clock and reset distribution must follow the datasheet topology, and unused pins must remain in their specified safe states. Timing constraints should be applied to the actual tool version and design because device speed, interconnect paths, product-term routing, and registered or combinational assignments determine final system performance. This page combines the verified device summary, source links, structured technical specifications, application guidance, and honest replacement analysis. It also separates confirmed facts from missing parameters so procurement and engineering teams can identify what must be checked in the manufacturer documentation before PCB release.
LC4032C-5T44C - 400MHz SuperFAST CPLD | Lattice Semiconductor
Lattice Semiconductor LC4032C-5T44C is a 32-macrocell, in-system-programmable SuperFAST CPLD in a 44-pin TQFP package. It supports 3.3 V, 2.5 V, and 1.8 V supply operation, reaches a maximum operating frequency of 400 MHz, and provides a 2.5 ns propagation delay. These characteristics position the device for glue-logic, interface bridging, control, and system-level programmable logic designs requiring fast timing and in-system reconfiguration. A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines configurable logic blocks and programmable interconnect. In the product hierarchy, a CPLD belongs to programmable logic devices alongside FPGAs. Unlike mask-programmed logic, a CPLD can be configured by the end user after manufacture. The LC4032C belongs to Lattice's ispMACH 4000 family, described in the manufacturer datasheet as a blend of the ispLSI 2000 and ispMACH 4A architectures. The device provides 32 macrocells and up to 80 product terms per output. It includes up to four global clock pins with programmable clock polarity control, enabling deterministic clock distribution across compatible logic functions. The -5 speed designation corresponds to the cited 400 MHz maximum operating frequency, while the C suffix identifies the 1.8 V-capable version within the family's 3.3 V, 2.5 V, and 1.8 V supply options. The 44C package suffix identifies the 44-pin TQFP physical configuration. In-system programmability permits configuration over the board's programming interface, useful for manufacturing, field updates, and designs that need programmable logic behavior without changing external components. The verified source describes the device as an ispMACH 4032B with 32 macrocells. Exact pin assignments, bank voltage limits, absolute maximum ratings, and package dimensions must be checked against the manufacturer datasheet before schematic sign-off or PCB release. Typical applications include bus-interface adapters, peripheral controllers, arbitration and decode logic, data-format conversion, industrial control modules, instrumentation front ends, and FPGA glue logic. Its 2.5 ns propagation delay is valuable where combinational decisions must settle rapidly, while the 400 MHz ceiling supports demanding clocked logic when board-level timing budgets allow. Design with this CPLD using the manufacturer pinout and timing constraints. Account for configuration pins, dedicated ground and power pins, decoupling, signal integrity, and programming-interface access. Because its logic performance is highly dependent on routing and architecture, treat the maximum frequency as a device-family headline rather than a guaranteed system-level frequency without timing verification. This page consolidates the verified distributor listing, family-level performance data, package identity, practical implementation notes, and replacement analysis. It is intended to help engineers evaluate the LC4032C-5T44C and distinguish exact same-package variants from options requiring different footprints, speed grades, temperature grades, or programming-system validation.
LC4032C-5T44I - 32-Macrocell 400MHz CPLD | Lattice
The Lattice Semiconductor LC4032C-5T44I is a 3.3V/2.5V/1.8V in-system-programmable SuperFAST high-density PLD with 32 macrocells, a maximum operating frequency of 400MHz, and a 2.5ns propagation delay. It is supplied in a TQFP PLD package identified by the 44-pin ordering code. A CPLD is a complex programmable logic device: a user-programmable semiconductor that combines programmable logic structures with a defined pin architecture. Within the broader FPGA & CPLD category, a CPLD is generally selected when deterministic timing, in-system programmability, compact logic integration, and a straightforward package are more important than the very high logic density of an FPGA. The LC4032C belongs to Lattice's ispMACH 4000 family and supports 3.3V, 2.5V, and 1.8V supply options. The verified device data identifies up to four global clock pins with programmable clock polarity control, routing to as many as 80 physical outputs. Its -5 speed designation is associated with the published 400MHz maximum operating frequency and 2.5ns propagation-delay class. The -5T44I ordering information identifies the package and industrial-temperature ordering variant, although the exact numeric temperature limits and package dimensions were not supplied in the verified excerpts. The LC4032C-5T44I is useful for control logic, bus decoding, state machines, interface glue, clock-domain-adjacent control functions, and general-purpose signal processing that benefits from deterministic CPLD timing. In-system programming allows a board to be configured or reconfigured without removing the device, supporting production programming, field updates, and logic revisions when the system architecture is designed for it. Designers should preserve the device's documented power, clock, programming, and decoupling requirements from the full LC4032C datasheet. Treat every clock distribution, output enable, and I/O standard as a timing-constrained path, and verify unused pins, signal integrity, and power sequencing before release. Because only verified excerpts were supplied, exact I/O counts, memory details, supply-current limits, temperature range, and package dimensions remain marked for data completion rather than being inferred. This page combines verified product facts, sourcing evidence, application guidance, and replacement constraints. It deliberately avoids unverified cross-brand claims: the supplied web results confirm the device and its family characteristics but do not establish a qualified, pin-compatible replacement in the same TQFP package.
LC4032C-5T48C - 32-Macrocell 5ns CPLD | Lattice
The Lattice Semiconductor LC4032C-5T48C is a 32-macrocell complex programmable logic device with a listed 5 ns speed grade, supplied in a 48-pin TQFP package. The verified distributor records identify it as a super-fast high-density PLD/CPLD and expose the ordering code LC4032C-5T48C-ND for procurement. The package combines programmable combinational and registered logic with nonvolatile configuration retention, making the device useful where control, decoding, interface adaptation, and fixed-format digital logic must be consolidated onto one programmable component. A CPLD is a user-programmable digital logic device that sits between fixed-function gate arrays and higher-end FPGAs in the broader semiconductor hierarchy. Unlike a microcontroller that executes software sequentially, a CPLD configures interconnected logic blocks into parallel hardware circuits. That architecture can provide deterministic control behavior without a software event loop, while in-system programmability supports design iteration, configuration storage, and field updates when the surrounding platform supports them. The verified source identifies the LC4032C family as a super-fast, high-density PLD, while the distributor ordering code identifies this exact variant as a 32-macrocell device with a 5 ns speed designation in a 48-pin TQFP package. Those are the only performance values confirmed in the supplied data. Core supply voltage, macrocell architecture details, I/O standards, propagation-delay breakdown, maximum operating frequency, current consumption, and supported input/output counts remain unverified and must be confirmed in the manufacturer datasheet before release to production. Typical uses include industrial control logic, peripheral glue, bus decoding, state-machine implementation, data-format conversion, board-level sequencing, and embedded subsystem interfaces. A CPLD is especially useful when several small control blocks must operate concurrently, external logic has grown beyond simple gates, or a product revision is likely. The exact architecture should be selected by compiling the intended design with the supported Lattice toolchain and checking timing against the external interface requirements. The 48-pin TQFP is a PCB-surface-mount package associated with the TQFP family. Before layout, verify the exact pin assignments, exposed-pad status, pin multiplexing, and programming interface from the official LC4032C documentation. The compact package helps reduce board area, but fine-pitch routing requires adequate clearances, a reliable ground plane, and careful decoupling around every applicable supply pin. A practical design review should compare the 5 ns family designation with the actual timing closure required by the slowest clock-domain crossing or I/O path. Device speed grade alone does not guarantee system timing; board delay, external component delay, constraints, and selected I/O mode must be included. For sourcing, compare the DigiKey, Octopart, and distributor availability records as of 2026-10-23, then obtain an authorized quotation for production quantities. This page consolidates the verified distributor descriptions, package and device-class details, sourcing links, and engineering cautions for LC4032C-5T48C. It deliberately distinguishes confirmed MPN data from electrical parameters that remain unavailable, helping engineers locate the part, assess package compatibility, and plan the next verification step without treating unconfirmed specifications as production facts.
LC4128V-75TN100C - 128-Macrocell CPLD, 7.5ns TQFP-100 | Lattice
The Lattice Semiconductor LC4128V-75TN100C is a 128-macrocell, 3.3V/2.5V/1.8V In-System Programmable SuperFAST High-Density CPLD from the ispMACH 4000V family, housed in a 100-pin TQFP (TN) package. It delivers a 7.5 ns pin-to-pin propagation delay (tPD) and supports a 400 MHz maximum internal operating frequency, making it one of the fastest non-volatile logic devices in its density class. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic device that implements combinatorial and sequential logic in a single chip, typically organized as multiple PAL-like logic blocks connected by a programmable interconnect matrix. CPLDs sit below FPGAs in logic density but offer faster, more deterministic propagation delays and instant wake-up from power-on, which is why they are favored for glue logic, bus bridging, and control-plane applications. Key features of the LC4128V-75TN100C include 128 macrocells across 4 logic blocks (32 macrocells per block), 64 user I/O pins, JTAG-based IEEE 1149.1 boundary-scan and in-system programmability, four global clock pins with programmable polarity, and a 3.3V core with multi-voltage I/O supporting 1.8V, 2.5V, and 3.3V interfaces. Power consumption is managed through per-macrocell product-term steering and a low-power standby mode. The device is built on a non-volatile E2CMOS process, which means configuration is retained without external memory and the part is ready to operate within microseconds of power-up. The wide I/O voltage compatibility allows direct interfacing with legacy 5V-tolerant buses through external resistors and with modern 1.8V/2.5V/3.3V processors without level shifters. Typical applications include bus-interface bridging (PCI to local bus, address decoding), glue logic in industrial controllers, power-sequencer replacement of discrete logic, and feature expansion for ASIC/microcontroller pin-limited designs. It is commonly used in telecom line cards, motor-control boards, and instrumentation front-ends where deterministic timing is required. When designing with the LC4128V-75TN100C, ensure the JTAG chain order is correctly defined for ISP, observe the 3.3V supply ramp requirements, and verify that the chosen I/O standard matches the bank voltage. Unused I/O pins must be configured as outputs or tri-stated with the proper termination to avoid leakage.

LC4128ZE-7MN144C - 128-Macrocell 1.8V Ultra-Low-Power CPLD | Lattice
The Lattice Semiconductor LC4128ZE-7MN144C is a 128-macrocell ultra-low-power CPLD from the ispMACH 4000ZE family, housed in a 144-ball CSBGA (7x7 mm, 0.5 mm pitch) package. It features 96 user I/O, 8 logic blocks, a 7.5 ns pin-to-pin propagation delay (tpd), and a maximum internal operating frequency of 172 MHz. The device operates from a single 1.8 V core supply (1.7 V to 1.9 V) and is in-system programmable through a standard IEEE 1532 / JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like AND/OR arrays with a central switch matrix. CPLDs sit between discrete glue logic (74-series gates) and FPGAs in the programmable logic hierarchy: like discrete logic they boot instantly from on-chip flash, and like FPGAs they implement arbitrary combinatorial and sequential functions. The ispMACH 4000ZE family specifically targets battery-powered and portable applications where static and dynamic power consumption are critical. Key differentiating features include Lattice's ultra-low-power 1.8 V architecture, per-pin slew-rate control, 3.3 V tolerant I/O with 5 V tolerant inputs, in-system programmability via JTAG, and a commercial operating temperature range of 0C to +90C (TJ). The CSBGA-144 package is footprint-compatible with the rest of the ispMACH 4000ZE family (64, 128, 256, and 512 macrocell densities in the same 144-ball outline where applicable), enabling designers to migrate density up or down without PCB rework. Architecturally, each macrocell contains a programmable AND array feeding an OR array, a flip-flop, and a feedback path. Eight logic blocks are interconnected by a global routing pool, providing predictable, deterministic timing with zero-fanout delays independent of placement. This makes the LC4128ZE-7MN144C well suited to replace multiple 74LV logic chips with a single in-system reconfigurable device while preserving exact cycle-accurate behavior. Typical applications include portable handheld and battery-powered consumer products, digital camera and camcorder glue logic, low-power instrumentation, LCD display timing controllers, and I2C/SPI/UART bus bridging/level shifting. The ultra-low static current also makes it attractive as a power-management sequencer in always-on subsystems of larger SoCs. Designers should note that 96 I/O is the maximum user I/O count - the actual usable count depends on JTAG programming pin sharing. Always use Lattice's ispLEVER Classic or Lattice Diamond (with the ispMACH 4000ZE support files) for synthesis and fitting to guarantee timing closure. The CSBGA package requires careful PCB layout with microvia or via-in-pad technology to escape the 0.5 mm ball pitch.
