The "-15" speed grade provides a 15 ns pin-to-pin propagation delay with an internal frequency up to 145 MHz, and the device supports configurable I/O standards at 3.3 V or 5.0 V operation. It is built on a high-performance CMOS EEPROM-based process using Altera's third-generation Multiple Array MatriX (MAX) architecture. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PLA-like logic array blocks (LABs) connected through a programmable interconnect matrix (PIA). Within the broader taxonomy, the EPM9560RI240-15 sits in this hierarchy: programmable logic device -> CPLD -> EEPROM-based CPLD -> MAX architecture CPLD -> high-density (>500 macrocell) CPLD. Compared to FPGAs, CPLDs offer deterministic timing, no configuration load time, and superior pin-locking and I/O count for glue-logic, bus-interface, and state-machine applications. The EPM9560RI240-15 provides 191 user I/O pins (industrial version) with 4 dedicated inputs, JTAG-compliant in-system programmability via IEEE Std 1149.1, and a 5.0 V core with multi-voltage I/O. Each macrocell supports combinatorial or registered logic with programmable polarity, a D/T/JK/SR flip-flop, and a product-term-based local feedback path. The 240-pin RQFP package is a surface-mount gull-wing variant with a 0.500 mm terminal pitch. Typical applications include industrial automation controllers, telecommunications line cards, peripheral bus interface bridges, legacy peripheral glue logic, and consumer electronics requiring deterministic sub-25 ns logic response. Designers favor the MAX 9000 series for power-up instant-on behavior (no external boot PROM required), making it ideal for systems that must begin operation immediately after VCC is applied. When designing, ensure monotonic VCC rise per Altera's Operating Requirements; during transitions I/O pins may undershoot to -2.0 V or overshoot to 7.0 V for periods shorter than 20 ns under no-load conditions. A robust decoupling network (one 0.1 uF per VCC/ground pair, plus bulk) is required to keep internal frequency up to 145 MHz. Industrial-grade operation is supported from -40 C to +85 C.

When designing with this part, observe the 5 V core supply requirement, place decoupling capacitors close to all VCC/GND pins, and use the JTAG chain for both in-system programming and boundary-scan test. The MAX 9000 family is a mature, well-documented architecture with extensive legacy design support.
EPM9560RI240-20N - MAX 9000 CPLD, 560 Macro, 191 I/O | Intel
The Intel EPM9560RI240-20N is a high-density, 5.0-V in-system programmable Complex Programmable Logic Device (CPLD) from the MAX 9000 family, providing 560 macrocells and 191 user I/Os in a 240-pin BGA-style power-enhanced package. It is built on a third-generation Multiple Array MatriX (MAX) architecture that combines the density of FPGAs with the predictability and non-volatility of classic PLDs, and is fabricated with a CMOS EEPROM process that supports 5.0-V in-system programmability through the IEEE 1149.1 JTAG interface. The device delivers an internal frequency up to 145 MHz with a pin-to-pin propagation delay of 11.4 ns, making it suitable for high-performance glue logic, bus interfacing, and state-machine heavy designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses on-chip EEPROM or flash memory to store the configuration. CPLDs sit in the programmable logic hierarchy between simple PLDs (PALs/GALs) and FPGAs: they offer deterministic timing (fixed propagation delay), instant-on operation (no external boot memory), high drive strength, and a Logic Array Block (LAB) structure connected by a programmable interconnect matrix (PIA). The MAX architecture extends classic CPLD concepts with finer-grained logic elements (macrocells), more flexible I/O, and higher usable density, and the 9000 series is positioned as the high-density tier of that family tree. Key features of the EPM9560RI240-20N include 560 dedicated macrocells (12 Logic Array Blocks), a maximum internal operating frequency of 145 MHz, 11.4 ns propagation delay through the PIA, multiVolt I/O supporting 5.0-V and 3.3-V mixed-voltage interfaces, and a 5.0-V core supply. The die supports user-configurable I/O standards, in-system programmability via JTAG, and is supported by the legacy Altera MAX+PLUS II and Quartus II design environments. Device power is estimated using Altera's PowerPlay power estimation methodology integrated into those tools. The MAX architecture uses each macrocell to implement a sum-of-products combinatorial function plus an optional flip-flop, with fast feedback paths to the PIA. Global routing is deterministic, which means designers can compute worst-case timing paths analytically - useful for asynchronous bus bridges, interrupt controllers, and other latency-critical glue logic. The 5.0-V tolerant I/O and strong drive capability allow direct interface to TTL/CMOS buses without external transceivers. Typical applications include high-performance bus interfacing (PCI, VME, ISA bridges), address decoding and wait-state generation in microprocessor systems, state-machine controllers for industrial and telecom equipment, glue logic for ASIC/FPGA-based designs, and high-pin-count glue logic on VME/cPCI backplanes. The 191 user I/O pins enable direct fan-out to wide memory buses and peripheral banks without additional buffering. When designing with this device, allocate global clocks carefully - the MAX 9000 has a finite number of global clock pins and LAB-local clock resources. Use the MAX+PLUS II fitter report or Quartus compilation report to verify pin assignments and resource utilization, and respect the 5.0-V VCCIO requirements if mixing with 3.3-V peripherals through level-shifting I/O standards. Decoupling bulk 0.1 uF and 10 uF capacitors should be placed as close as possible to every VCC/VCCIO pin to meet in-system programming noise margins.

Typical applications include industrial control backplanes, telecom line-card glue logic, legacy system maintenance, test equipment, and military/aerospace programs where 5 V logic and non-volatile configuration are mandatory. The industrial temperature grade (-40C to +85C) supports deployment in factory-floor and outdoor equipment. When designing with the EPM9560RI304, note that the device is configured via the JTAG interface and requires a 5.0 V supply with careful decoupling on every VCC pin. Because the part is a legacy MAX 9000 device, designers should confirm lifecycle status and consider MAX II or MAX V migration for new designs.

The device is implemented in 0.5 µm CMOS EEPROM technology with on-chip charge pumps for in-system programming, eliminating the need for external boot memory. The MAX architecture uses a uniform interconnect that lets every macrocell drive every I/O pin, simplifying place-and-route while preserving fixed, application-independent timing. Typical applications include 32-bit and 64-bit bus decoding, peripheral glue logic in telecom and industrial controllers, address mapping and chip-select generation, and high-density state machines. The 304-pin package provides ample I/O for parallel interfaces, while the 560-macrocell capacity supports logic equivalent to several thousand gates. When designing with this part, ensure that the JTAG chain is correctly terminated (TCK pulled low, TMS pulled high at reset) and that I/O banks are powered within the 3.3 V or 5 V rail specifications. Decoupling of each VCC pin with 0.1 µF ceramics placed within 5 mm of the pin is essential for reliable ISP operation.

The Altera EPM9560RI304-15N is a high-density CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 family, delivering 560 macrocells and 772 flip-flops in a 304-pin RQFP package. It features a maximum internal frequency of 145 MHz, a propagation delay of 15 ns through the worst-case interconnect, and supports configurable I/O operation at 3.3 V or 5.0 V. The device is implemented in 5.0-V in-system programmable EEPROM technology built on the third-generation Multiple Array MatriX (MAX) architecture. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that sits between small-scale discrete logic (74-series gates) and large FPGAs in the programmable logic hierarchy. CPLDs use a classic AND-OR programmable plane feeding a fixed number of macrocells, giving them deterministic, fast, pin-to-pin propagation delays and instant-on behavior from non-volatile EEPROM configuration memory. They are commonly used for glue logic, bus interface bridging, address decoding, and state-machine control where predictable timing matters more than raw logic density. Key features of the EPM9560RI304-15N include 16 Logic Array Blocks (LABs) interconnected by the Programmable Interconnect Array (PIA), 216 user I/O pins, JTAG-based IEEE 1532 in-system programmability, and pin-compatibility across the MAX 9000 family. The RQFP-304 (also referenced as HFQFP-304 in distributor data) provides a 1.27 mm gull-wing pitch for surface-mount assembly. Per the Altera MAX 9000 datasheet, the device supports multi-volt I/O and operates across the commercial 0 C to 70 C range. Architecturally, the EPM9560RI304-15N combines the predictable timing of EEPROM-based macrocells with the density and routability of a structured interconnect, making it well suited to mid-complexity logic replacement (hundreds to a few thousand gates) and peripheral expansion. The 15 ns speed grade is the mid-tier timing bin, balanced between pin-to-pin delay and static power consumption. Designers use MAX 9000 CPLDs for I/O expansion, bus decoding, address mapping, and as glue logic between microprocessors, microcontrollers, and FPGAs. Typical applications include legacy peripheral replacement, glue logic in industrial controllers, bus address decoding for PowerPC/MIPS/ARM boards, JTAG-controlled I/O expansion, and rapid prototyping of state machines. The combination of non-volatile instant-on configuration, JTAG programming, and deterministic timing also makes it attractive in safety-related industrial equipment where predictable behavior at power-on is required. When designing with the EPM9560RI304-15N, ensure the supply voltage and I/O bank voltages match the JTAG chain order and other boundary-scan devices. Decoupling follows standard high-pin-count CMOS practice: 0.1 uF ceramic bypass on every VCC/VCCIO pin pair and a single bulk 10-47 uF tantalum or ceramic near the package. Because the device is 5-V core with multi-volt I/O, level translation is handled on-chip but input over-voltage on 3.3 V banks must be respected. The Altera MAX+PLUS II or Quartus MAX device support file is required for synthesis.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that retains configuration without external memory and offers deterministic, near-zero propagation delay suitable for glue logic, bus interfacing, address decoding, and state-machine replacement. Within the broader programmable logic hierarchy, CPLDs sit between simple SPLDs (PAL/GAL) and high-density FPGAs, offering predictable timing, instant-on operation, and high I/O counts that FPGAs in the same cost class cannot match. Key features include 5.0 V in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface, 304 user I/O pins, 212 inputs with fast input logic, a 100 MHz internal performance grade, and CMOS-compatible I/O. The EPM9560RI304-20N variant carries the -20 speed grade (20 ns tPD), making it the slowest but most cost-optimized option in the EPM9560RI304 family versus the -15 and -10 grades. Architecturally, the device partitions logic across LABs of 16 macrocells each, with each macrocell supporting product-term allocation, D/T/JK flip-flop configuration, and global/array clock selection.

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.

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.

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.

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.

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.

The device includes on-chip oscillator, PLL, and configuration logic, reducing external component count. Its non-volatile nature ensures the FPGA is ready immediately at power-up, a critical feature for system control and boot sequencing. Typical applications include system management, I/O expansion, motor control, and display interfaces. The low power consumption and instant-on capability make it ideal for portable and battery-powered devices. In industrial settings, it can serve as a bridge between different voltage domains or as a flexible glue logic solution. When designing with this FPGA, pay attention to power supply decoupling and I/O bank voltage requirements. The device supports multiple I/O standards, and proper termination may be needed for high-speed signals. Also, consider using Lattice's free design software, Diamond, for synthesis and implementation.
M1AFS1500-1FG256 - Fusion FPGA 1.5M Gates ARM Cortex-M1 | Microchip
The Microchip Technology M1AFS1500-1FG256 is a Fusion mixed-signal FPGA with 1.5 million system gates, 38,400 logic cells, 119 user I/Os, and 276,480 bits of flash memory, housed in a 256-ball LBGA (FG256) package with an embedded ARM Cortex-M1 processor. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. The Fusion family extends this concept by integrating configurable analog blocks, large flash memory, clock management circuitry, and flash-based programmable logic in a single monolithic die - placing it in the device hierarchy: FPGA -> programmable logic device -> programmable SoC -> mixed-signal IC. Key features include the embedded ARM Cortex-M1 soft processor core implemented in the fabric, integrated analog-to-digital conversion for mixed-signal sensing, flash-based configuration that is instant-on and highly secure, and comprehensive on-chip clock generation and management. The 276,480-bit flash memory block can store firmware or configuration data, reducing external component count. Architecturally, the device uses Microsemi (now Microchip) flash-based VersTiles with fine-grained logic, delivering non-volatile configuration without external boot PROM - a significant security and bill-of-materials advantage over SRAM FPGAs. Typical applications include industrial control and motor drives, aerospace and defense systems, medical instrumentation, and embedded mixed-signal monitoring where single-chip integration of analog, digital logic, and a processor is valuable. Design consideration: the 256-ball BGA requires controlled-impedance PCB layout and X-ray inspection capability for assembly rework; verify flash programming via the JTAG/FlashPro interface early in development.

M1AFS1500-1FG256I - Fusion FPGA 1.5M Gates 256-LBGA | Microchip
The Microchip Technology (formerly Microsemi/Actel) M1AFS1500-1FG256I is a Fusion mixed-signal FPGA delivering 1.5 million system gates with 119 user I/O and an embedded ARM Cortex-M1 hard processor core, housed in a 256-ball LBGA (FG256) package in industrial temperature grade. A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks, routing resources, and I/O cells that designers program to implement custom digital circuits. Unlike ASICs, FPGAs are reprogrammable in the field. The Fusion family extends this concept by integrating configurable analog blocks, flash memory, and clock management on a single monolithic die, positioning it as a complete programmable system-on-chip within the broader power-management and embedded-processing hierarchy. Key differentiating features of the M1AFS1500-1FG256I include flash-based nonvolatile configuration that retains the program when powered off, Live at Power-Up (LAPU) operation that eliminates the need for external boot configuration, and single-chip integration that removes external configuration PROMs. The 130-nm, 7-layer metal flash-based CMOS process supports up to 350 MHz system performance. The industrial (I) grade supports operation from -40C to +85C. Technically, the die integrates the programmable fabric, large flash memory blocks (the part listing shows 276480 bits of associated memory resource), comprehensive clock generation and management circuitry, and configurable analog peripherals in a monolithic device. The M1 prefix denotes the Fusion variant with the ARM Cortex-M1 processor embedded, enabling a soft-to-hard migration path for embedded firmware alongside programmable logic in one die. Typical applications include industrial automation and control, motor drive and power-supply supervision leveraging the mixed-signal analog blocks, embedded systems needing an ARM Cortex-M1 plus FPGA fabric combination, and single-chip designs where nonvolatile, instant-on configuration is required. A key design consideration is compliance: per distributor data this specific device is RoHS non-compliant and contains lead, so it must not be substituted casually for lead-free (FGG) variants in RoHS-restricted products; verify the appropriate suffix for your regulatory environment.
