EPM240T100I5

EPM240T100I5 - 240-LE MAX II CPLD, TQFP-100, 3.3V | Intel / Altera

The Intel / Altera EPM240T100I5 is a 240-logic-element MAX II family Complex Programmable Logic Device (CPLD) housed in a 100-pin TQFP package with industrial temperature grade (-40C to +100C junction). It integrates non-volatile flash configuration storage of 8 Kbits, supports MultiVolt I/O from 1.5V to 3.3V, and delivers typical pin-to-pin propagation delays in the 4-7 ns range. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy (CPLD -> programmable logic -> digital logic IC -> semiconductor). Unlike SRAM-based FPGAs that require external boot flash, MAX II CPLDs store configuration in on-chip flash, so they power up instantly into a known state - ideal for control-plane glue logic that must be live before any processor boots. Key features include 192 macrocells (equivalent), 240 logic elements, a MultiVolt core allowing 3.3V operation, an integrated User Flash Memory (UFM) block of 8 Kbits, JTAG-based in-system programmability (ISP), and support for the IEEE 1149.1 boundary-scan standard. The device supports I/O standards including LVCMOS, LVTTL, and PCI. The MAX II architecture uses a 6-layer-metal flash process with a uniform interconnect fabric, providing deterministic timing that simplifies static timing closure versus FPGA architectures. Vertical migration within the same TQFP-100 package is supported with the EPM570 and EPM1270, enabling density upgrades without PCB rework. Typical applications include I/O expansion and bus bridging in industrial controllers, power-sequencing logic, address decoding for memory subsystems, and LED/display driving in consumer electronics. The instant-on nature of flash storage also suits safety and fault-response circuits where deterministic startup timing is required. When designing with this device, derate the I/O current per the datasheet's DC characteristics table and confirm that the chosen Quartus II / Intel Quartus Prime device library matches the I5 speed grade. Always use the JTAG chain for production programming to support field updates.

EPM240T100I5N - 240 LE MAX II CPLD, 100-pin TQFP | Intel
EPM240T100I5N

EPM240T100I5N - 240 LE MAX II CPLD, 100-pin TQFP | Intel

The Intel (formerly Altera) EPM240T100I5N is a non-volatile, instant-on Complex Programmable Logic Device (CPLD) from the MAX II family, delivering 240 logic elements (LEs) and 192 macrocells in a 100-pin TQFP package. It is built on a 0.18-µm, 6-layer-metal flash process and integrates 8 Kbits of on-chip user flash memory (UFM), with MultiVolt I/O supporting output levels compatible with 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V systems. The industrial temperature grade (-40 °C to +100 °C ambient) and flash-backed configuration make it suitable for harsh-environment embedded designs. What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-configurable digital logic IC that replaces discrete glue-logic gates, muxes, and small state machines. CPLDs sit below FPGAs in the programmable-logic taxonomy (CPLD -> programmable logic -> digital IC -> semiconductor), offering deterministic timing, single-chip boot, and lower static power than equivalent FPGA implementations. The MAX II architecture moves the configuration storage into flash so the device behaves like an ASIC at power-up with no external PROM required. Key features of the EPM240T100I5N include 80 user I/O pins, four I/O banks with independent VCCIO rails, a JTAG-based IEEE 1149.1 boundary-scan / ISP interface, and a MultiVolt core that operates from a single 3.3 V supply while interfacing to mixed-voltage rails. Typical pin-to-pin propagation delays sit around 7 ns and the device supports in-system programmability through the Quartus II / Quartus Prime toolchain. From an architecture standpoint, the 240 LEs are organized into Logic Array Blocks (LABs), each containing 10 LEs, with interconnect driven by the MultiTrack interconnect fabric. The embedded UFM (8 Kbits) can store user data such as serial numbers, calibration constants, or boot parameters, eliminating a small EEPROM in many designs. The non-volatile flash also removes the boot-time configuration delay common to SRAM-based FPGAs. Typical applications include I/O expansion and bus bridging between microcontrollers and peripherals, power-sequencer and supervisory logic, glue-logic replacement on industrial PCBs, LED-control drivers, and protocol-bridging glue for I2C/SPI/UART multiplexing. Its flash-backed instant-on behavior is also valued in motor-control and safety-critical industrial systems where deterministic startup is required. Designers should note that the MAX II family is in mature, long-life supply status; verify long-term availability with the vendor before committing to new high-volume designs, and consider the MAX V family (5M240ZT100C5N) as the pin-compatible next-generation option with a 1.8 V core. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond the manufacturer datasheet, organized for engineers sourcing the EPM240T100I5N today.

EPM240T1OOC5N

EPM240T1OOC5N - MAX II CPLD, 192 Macro Cells, 100-TQFP | Intel

The Intel (Altera) EPM240T1OOC5N is a MAX II instant-on, non-volatile CPLD from the MAX II Device Family featuring 192 macro cells (240 logic elements) at up to 201.1 MHz internal performance, fabricated on a 0.18 µm, six-layer-metal flash process in a 100-pin TQFP package with 2.5 V/3.3 V operation. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix. CPLDs sit below FPGAs in density and sit above discrete 74-series glue logic in flexibility; they are used for I/O expansion, bus bridging, power-up sequencing, and state-machine replacement where deterministic, low-latency, non-volatile behavior is required. The MAX II family adds 8 Kbits of user flash memory and removes the legacy EEPROM/CMOS-cell architecture of MAX 7000, lowering power and cost. Key features include 192 macro cells, 80 I/O pins, 8 Kbits of internal user flash memory, JTAG-based in-system programmability (IEEE 1149.1), 4-input look-up tables, and zero-power versus commercial junction temperature grades. The 100-pin TQFP package supports vertical migration to higher-density MAX II devices (EPM570, EPM1270, EPM2210) in the same footprint, preserving PCB design across multiple logic-density points. Architecturally, the EPM240T100C5N uses a non-volatile flash-based configuration cell so it powers up in a defined state within microseconds - a major advantage over SRAM FPGAs that require an external boot PROM and configuration time. MultiVolt I/O supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces from a single 3.3 V core supply, simplifying mixed-voltage board designs. Typical applications include I/O expansion and voltage translation in industrial control boards, glue logic replacement in telecom/networking line cards, bus-interface bridging (PCI to local bus, address decoding), power-up/power-down sequencing in ATCA/ATX platforms, and LED-control or motor-control state machines in consumer and industrial equipment. When designing with this device, use the Intel Quartus Prime design suite (free Web Edition supports MAX II) for synthesis, place-and-route, programming-file generation, and JTAG programming via the Altera USB-Blaster or compatible cable. Decouple all VCCINT/VCCIO pins with 0.1 µF capacitors placed within 100 mils of the package pins.

EPM240ZM100C6N

EPM240ZM100C6N - 192-Macrocell CPLD, 100-MBGA, Zero-Power | Intel

The Intel (formerly Altera) EPM240ZM100C6N is a 192-macrocell MAX II zero-power CPLD housed in a 100-pin Micro FineLine BGA (MBGA) package, fabricated on a 0.18-µm 6-layer-metal flash process. It provides 240 logic elements (LEs), 80 user I/Os, a 7.5 ns pin-to-pin propagation delay, and an internal clock network supporting up to 184.1 MHz. The instant-on, non-volatile flash-based architecture delivers the deterministic power-on behavior of an ASIC with the design flexibility of a programmable logic device, eliminating the external configuration PROM required by SRAM-based FPGAs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with a central interconnect matrix. CPLDs sit in the programmable logic hierarchy alongside FPGAs, but are distinguished by their non-volatile (instant-on) configuration, deterministic timing, and suitability for glue-logic, interface bridging, and control-plane applications. MAX II belongs to the broader programmable logic device (PLD) family, branching from simple PLDs (SPLDs) through CPLDs and FPGAs into system-on-chip (SoC) FPGAs. Key features include MultiVolt core support, allowing the device to interface with 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic without level shifters; an integrated User Flash Memory (UFM) block of up to 8 Kbits for non-volatile data storage; four global clocks with two clocks per logic array block; and standby current as low as 25 µA. The Z-suffix device provides the lowest-power variant of the MAX II family, well suited to battery-backed and energy-conscious designs. Typical applications include bus interface bridging (e.g., 8-bit MCU to 32-bit bus), power-up sequencing logic, I/O expansion for low-pin-count microcontrollers, configuration control for FPGAs and memories, and digital signal conditioning. Its compact 6 × 6 mm footprint makes it attractive for space-constrained PCBs in industrial control, consumer electronics, and portable instrumentation. Designers should note that the MBGA package requires careful PCB layout - micro-via fan-outs and controlled-impedance routing are recommended. The device operates over a 1.8 V core supply with MultiVolt I/O, and supports JTAG-based in-system programmability (ISP) for field updates.

EPM240ZM100C7N - MAX II Z CPLD 192MC 7.5ns 100-MBGA | Altera/Intel
EPM240ZM100C7N

EPM240ZM100C7N - MAX II Z CPLD 192MC 7.5ns 100-MBGA | Altera/Intel

The Altera (Intel) EPM240ZM100C7N is a low-power, non-volatile CPLD from the MAX II Z family with 240 logic elements (192 macrocells), 7.5 ns pin-to-pin logic delay, and 80 user I/Os housed in a 100-ball Micro FineLine BGA (MBGA) package. It is fabricated on a 0.18-µm 6-layer-metal flash process that integrates configuration storage on-die, eliminating the need for an external boot PROM. The device operates from a single 1.8 V core supply and supports MultiVolt I/O banks at 1.5 V, 1.8 V, 2.5 V, 3.3 V, and is pin-compatible with the corresponding MAX II G device in the same 100-pin MBGA. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that provides instant-on operation, deterministic timing, and flexible glue-logic integration between microcontrollers, ASICs, and standard bus interfaces. CPLDs sit below FPGAs in the programmable logic hierarchy: they typically offer lower density but faster, fully deterministic propagation delays, making them ideal for address decoding, bus interfacing, power-up sequencing, and peripheral control rather than high-throughput data-path or DSP workloads. The MAX II family is the lowest-power instant-on CPLD family in the Altera/Intel portfolio. Key features include 8 Kbits of on-chip user flash memory (UFM) for storing constants, serial numbers, or calibration data; a JTAG (IEEE 1149.1) interface for in-system programming and boundary-scan test; support for I/O standards including LVCMOS, LVTTL, PCI, and differential LVDS; and a typical standby current under 2 mA at 1.8 V core. The Z sub-family variant is engineered specifically for ultra-low static power dissipation, making it well suited to battery-powered and energy-harvesting designs where the device must idle for long intervals without draining the source. Architecturally, the EPM240ZM100C7N is built around the Logic Array Block (LAB) interconnect fabric, with each LAB containing 10 logic elements and each LE implementing a 4-input look-up table, a programmable register, and a carry chain. The MultiVolt I/O architecture lets each bank be powered independently from the core, allowing direct interfacing to legacy 5 V-tolerant buses through external series resistors or level shifters. The device retains all configuration in on-chip flash, so power-up time is governed only by the I/O ramp-up sequence rather than by a PROM load cycle. Typical applications include I/O expansion and address decoding for microcontrollers and microprocessors, power-up sequencing in multi-rail systems, glue logic in industrial control and factory automation boards, low-power portable and battery-backed instrumentation, LED display multiplexing, and consumer-electronics control boards. The 100-ball MBGA package has a footprint of approximately 6 x 6 mm, making it one of the smallest footprints available in the MAX II family. When designing with the EPM240ZM100C7N, plan the MultiVolt bank assignments carefully because each I/O bank shares a VCCIO rail and mixing 1.5 V and 3.3 V signals requires at least two banks. Use Quartus II Web Edition (or the latest supported Intel Quartus Prime release) for design entry, fitting, and in-system programming via the JTAG port.

EPM240ZM100I8N

EPM240ZM100I8N - MAX II CPLD, 192 Macro Cells, 100-MBGA | Intel

The Intel EPM240ZM100I8N is a low-power MAX II complex programmable logic device (CPLD) with 192 macro cells, 80 user I/Os, and a 7.5 ns pin-to-pin logic delay, housed in a 100-ball Micro FBGA (MBGA, 6x6 mm, 0.5 mm pitch) package. The 'Z' speed grade and 'I8' industrial temperature suffix confirm operation from -40C to +100C junction with sub-7.5 ns timing, while the device is fabricated on a 0.18 µm CMOS process and operates from a 1.8 V core supply. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy: CPLD -> programmable logic -> logic IC -> semiconductor. Unlike SRAM-based FPGAs, MAX II CPLDs use on-chip Flash configuration memory, providing instant-on behavior in <1 ms and deterministic, glitch-free I/O at power-up - which is critical for bus arbitration, glue logic, and power-supply sequencing. Key features include 192 macro cells organized into 4 logic array blocks (LABs) with 240 logic elements per LAB family, 80 maximum user I/Os, 7.5 ns tPD (pin-to-pin delay), 118.3 MHz internal performance, 1.8 V VCCINT core supply, 1.5 V to 3.3 V VCCIO multi-voltage I/O support, and built-in IEEE Std. 1149.1 JTAG boundary-scan. The MAX II architecture uses a MultiVolt core plus per-bank I/O voltage translators, allowing 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces from a single 1.8 V rail. Architecturally, the EPM240ZM100I8N routes signals through a continuous interconnect with fast propagation delays, while on-chip UFM (User Flash Memory, 8 Kbits) provides non-volatile parameter storage without an external EEPROM. The combination of low standby current (<2 mA typical), instant-on, and JTAG-driven in-system programmability (ISP) suits power-sensitive and field-upgradable designs. Typical applications include bus bridging and voltage-level translation between 3.3 V MCUs and 1.8 V peripherals, power-supply sequencing and supervisory glue logic, LED display driving, I/O expansion for microcontrollers without enough pins, and boot-loader/state-machine controllers in industrial, automotive, and consumer systems. When designing with the EPM240ZM100I8N, ensure the 100-MBGA PCB layout accommodates 0.5 mm-pitch BGA escape routing (microvia or HDI recommended) and that VCCINT and VCCIO decoupling follows the MAX II handbook recommendation of 0.1 µF + 1 µF ceramic capacitors within 3 mm of each supply pin.

EPM240ZM68C6N

EPM240ZM68C6N - 192 Macrocell CPLD 7.5ns 68-MBGA | Intel / Altera

The Intel / Altera EPM240ZM68C6N is a non-volatile, flash-based Complex Programmable Logic Device (CPLD) from the MAX II family, delivering 192 macrocells with a 7.5 ns pin-to-pin propagation delay in a 68-ball Micro FBGA package. It is fabricated on a 0.18 µm process, operates from a 1.8 V core supply, and supports user I/O at multiple voltage standards through banked VCCIO rails, providing a flexible glue-logic and bus-bridging platform for cost-sensitive designs. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on digital IC that combines multiple PAL-like logic blocks on a single die, with a programmable interconnect matrix routing signals between them. Architecturally, a CPLD sits between small glue-logic gate arrays (a few dozen gates) and full FPGAs (tens of thousands of LUTs with soft cores and SERDES). The MAX II family — to which the EPM240Z belongs — is Altera's (now Intel) zero-power CPLD line: it replaces the classic EEPROM or antifuse cell with on-chip flash configuration memory, eliminating the external boot PROM that legacy MAX devices needed and giving instant-on behavior similar to an FPGA with bitstream pre-loaded into flash. Key features of the EPM240ZM68C6N include 192 macrocells (~240 logic elements in legacy Altera nomenclature, hence the '240' prefix), 184.1 MHz internal performance, 80 user I/O pins broken into I/O banks, multi-voltage support (1.5 V, 1.8 V, 2.5 V, 3.3 V I/O standards) via banked VCCIO, in-system programmability through JTAG, and low standby current characteristic of the MAX II Z-series. The Micro FBGA-68 package is a chip-scale BGA suited to high-density PCB designs where board area is constrained. The architecture combines Look-Up Table (LUT) based logic array blocks (LABs) with a global interconnect that fans out across the die. Each macrocell contains a programmable flip-flop, product-term logic, and a configurable output buffer. Compared to discrete 74-series glue logic, the EPM240Z replaces dozens of packages with a single device while adding reconfigurability for late-stage design changes, BOM consolidation, and obsolescence management. Typical applications include bus-bridging between processors operating at different voltages, glue-logic replacement for 74HC/74LVC series gates, address decoding in microcontroller systems, LED driving and PWM generation, I/O expansion for FPGAs or microcontrollers with insufficient pins, and board-level power sequencing. Designers also use the device in industrial control, motor drive signal conditioning, and portable instrumentation where low standby current matters. When designing with the EPM240ZM68C6N, mind that the 68-ball Micro FBGA requires X-ray or careful hot-air rework for prototyping and that JTAG chain sharing must be planned if the board already contains an FPGA or another programmable device. The Intel Quartus II (or Quartus Prime Lite) toolchain supports this part with full synthesis, place-and-route, and timing analysis. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes — including JTAG chain sharing and decoupling strategy — to give an engineer a complete view beyond what the manufacturer datasheet alone provides.

The Z-series variant used here emphasizes zero-power standby consumption, suiting battery-aware systems. Key differentiating features of the EPM240ZM68C7N include its instant-on architecture (configuration time below 0.5 ms thanks to internal flash), zero standby current in shutdown mode, and MultiVolt I/O supporting mixed-voltage buses. The device provides 240 logic elements (192 equivalent macrocells), 8 Kbits of user flash, up to 123.5 MHz internal performance, and JTAG-based in-system programmability through IEEE 1149.1 boundary scan. The architecture uses a uniform logic element array interconnected by a continuous FastTrack routing fabric, with each LE containing a 4-input look-up table, a programmable register, and a carry chain for arithmetic operations. The non-volatile flash configuration bit cells eliminate external boot PROMs and provide design security, while the global clock network supports up to four dedicated clock pins with glitch-free MUX switching. Typical applications include I/O expansion and bus bridging in industrial control, power-up sequencing for FPGAs and processors, address decoding in networking equipment, peripheral glue logic in embedded systems, and LED display multiplexing. Its zero standby current and small Micro BGA footprint also suit portable and handheld designs. When designing with the EPM240ZM68C7N, note that the MBGA package requires careful PCB layout with microvia or via-in-pad technology, and that I/O banks must share a single VCCIO voltage. JTAG pins should be reserved for programming access, and unused pins must be left floating per the device handbook recommendation.

EPM240ZXXAA

EPM240ZXXAA - MAX II CPLD, 240 LE, 0.18um Flash | Intel

The Intel EPM240ZXXAA is a member of the MAX II family of instant-on, non-volatile Complex Programmable Logic Devices (CPLDs) built on a 0.18-micrometer flash-based process. The MAX II Z variant integrates 240 Logic Elements (LEs), non-volatile flash configuration memory, and an 8-Kbit user flash block, delivering instant-on single-chip logic in a compact BGA/MBGA package footprint. According to the Intel MAX II device handbook, the Z-series targets low-cost, low-power glue-logic applications where deterministic startup is required without external configuration memory. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy: CPLD -> programmable logic -> digital IC -> semiconductor. CPLDs typically use a macrocell-based AND/OR fabric with non-volatile configuration storage, which makes them instant-on (configuration is retained even when power is removed) and deterministic (no boot sequence or external flash PROM required). Compared to FPGAs, CPLDs offer lower logic density but simpler timing models, predictable I/O behavior, and better fit for glue logic, interface bridging, and power-up sequencing tasks. Key features of the EPM240ZXXAA include 240 Logic Elements, up to 80 user I/O pins, an internal oscillator, 8-Kbit user flash, JTAG boundary-scan support, and 3.3/2.5/1.8/1.5-V LVCMOS/LVTTL multi-voltage I/O capability. The device supports the Quartus II design software (legacy) and the Quartus Prime Lite edition for design entry, synthesis, and place-and-route. Each macrocell provides a flip-flop, product-term logic, and a programmable I/O buffer, allowing efficient implementation of state machines, decoders, and bus interface logic. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up sequencing for multi-rail systems, LED driving and display multiplexing, glue logic for microcontroller-based designs, and configuration of companion devices. The instant-on characteristic also suits automotive and consumer subsystems where deterministic startup is mandatory. When designing with the EPM240ZXXAA, confirm pin compatibility against the package variant (the XXAA suffix denotes a specific speed/package grade; consult the ordering information for the exact pin count and BGA ball map). Designers migrating from MAX II to MAX V may reuse the same JTAG and Quartus Prime flow without board rework when packages match.

EPM3032A-TC44-10 - 32-Macrocell 3.3V CPLD, TQFP-44 | Altera
EPM3032A-TC44-10

EPM3032A-TC44-10 - 32-Macrocell 3.3V CPLD, TQFP-44 | Altera

The Altera EPM3032A-TC44-10 is a member of the MAX 3000A family of high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs) built on the MAX architecture. It integrates 32 macrocells across 2 Logic Array Blocks (LABs) and provides 34 user I/O pins in a 44-pin Thin Quad Flat Pack (TQFP) package. Propagation delay is 10 ns with a maximum internal operating frequency of 227.3 MHz, and the device operates from a single 3.3 V supply (3.0 V to 3.6 V). A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single chip with a programmable interconnect matrix. Within the digital logic hierarchy, CPLDs sit between simple SPLDs (PALs/GALs) and FPGAs: they offer faster deterministic pin-to-pin timing than FPGAs, non-volatile on-chip storage unlike SRAM-based FPGAs, and higher density than legacy 22V10-style SPLDs. The MAX 3000A family targets glue-logic, bus-interface, and state-machine replacement tasks that previously required discrete 74LS/74HC logic or ASIC redesigns. Key features of the EPM3032A include 3.3 V in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface, six output enables for bus-oriented multiplexing, programmable power-saving mode per macrocell, and JTAG boundary-scan test support. The EEPROM configuration cell provides instant-on operation with no external boot PROM. Commercial operating temperature is 0 °C to 70 °C. The MAX architecture implements each macrocell with a programmable AND/OR array plus a configurable flip-flop, supporting combinatorial or registered outputs. The LAB interconnect uses a fast uniform delay matrix so any pin-to-pin path can be predicted by adding the routing delay to the macrocell delay, simplifying static timing analysis for critical control paths. Typical applications include JTAG-based board-level glue logic, address decoding and bus-interface bridges for 8/16-bit microcontrollers, I/O expansion for low-density FPGAs, and industrial control state machines. Its 34 I/Os comfortably support 32-bit datapath multiplexing plus control signals. When designing, observe 3.3 V I/O compatibility — the EPM3032A inputs are not 5 V tolerant, so external level translation is required when interfacing with 5 V logic. Use the Altera MAX+PLUS II or Quartus II design tools for compilation, fitting, and ISP programming.

The Altera (Intel) EPM3032A-TC44-10N is a 32-macrocell MAX 3000A family CPLD fabricated in advanced CMOS EEPROM technology, offering 600 usable gates, 34 user I/O pins, and a 10 ns pin-to-pin propagation delay in a 44-pin TQFP surface-mount package. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocells with a central programmable interconnect matrix. CPLDs sit between simple PLDs and FPGAs in the programmable logic hierarchy: PAL/GAL < PLD < CPLD < FPGA. The MAX 3000A family is Altera's classic low-cost, 3.3 V CPLD family targeting glue-logic, interface bridging, and state-machine consolidation in cost-sensitive industrial and consumer designs. Key specifications include 32 macrocells, 600 usable gates, 34 user I/O pins, a 4.5 ns pin-to-pin delay, a 227.3 MHz internal counter frequency, in-system programmability via JTAG (IEEE 1532), and 3.3 V single-supply operation. The device includes six global output enables and supports multi-voltage I/O through Altera's MAX architecture, making it suitable for bridging 5 V and 3.3 V logic domains. EEPROM-based configuration means the design retains its pattern after power-down without external boot memory. Architecturally, the EPM3032A uses Altera's classic Logic Array Block (LAB) structure with 16 macrocells per LAB and a continuous programmable interconnect array (PIA). Each macrocell contains a programmable AND/OR array, a flip-flop with configurable polarity, and a tri-state output buffer. This structure delivers predictable, deterministic timing that is critical for control-path logic, bus interfaces, and decoder/encoder replacement. Typical applications include address decoding and bus-interface glue logic in industrial controllers, power-supply sequencing and supervisory state machines, I/O expansion and protocol bridging (for example UART-to-parallel), LED-display drivers, and legacy ASIC/emulator replacement. The 44-pin TQFP package provides 34 usable I/O, well-suited to mid-complexity glue logic with moderate I/O requirements. When designing with this device, ensure your I/O assignments fit within the 34-pin budget and respect the JTAG programming-pin requirements (TMS, TDI, TDO, TCK). Use Altera's legacy MAX+PLUS II or Quartus II design software for synthesis, fitting, and ISP programming. The 3.3 V core and I/O simplify integration with modern low-voltage MCUs and ASICs.

EPM3032ALC-44-10N - MAX 3000A CPLD, 32MC, 10ns, 44-PLCC | Altera

The Altera (Intel) EPM3032ALC-44-10N is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, providing 32 macrocells and 34 user I/O pins in a 44-pin Plastic Leaded Chip Carrier (PLCC) package. It features 4.5 ns pin-to-pin logic delays with counter frequencies up to 227.3 MHz, delivering 600 usable gates of combinational and sequential logic. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that sits in the system hierarchy between simple SPLDs (PALs/GALs) and high-density FPGAs. CPLDs use EEPROM or flash configuration cells, providing instant-on behavior without external boot memory, and they are well-suited to glue-logic, bus-interface, and state-machine replacement tasks. The MAX 3000A family is one of the longest-running CPLD architectures, valued for its deterministic timing, low power, and ease of ISP (in-system programming). Key features of the EPM3032ALC-44-10N include 3.3 V core operation with the MultiVolt I/O interface, which allows I/O pins to interface with 5.0 V, 3.3 V, and 2.5 V logic levels without external level shifters. ISP conforms to IEEE Std. 1532 and is accessed via the built-in IEEE Std. 1149.1 (JTAG) interface. The device provides 4.5 ns tPD, a 10 ns tSU, and operates over the commercial 0C to +70C temperature range. Programming is performed through the JTAG chain using the Quartus II / MAX+PLUS II toolchain. Architecturally, the EPM3032ALC-44-10N organizes its 32 macrocells into 2 Logic Array Blocks (LABs), each fed by a programmable interconnect array. Each macrocell contains a programmable AND/OR array with a configurable flip-flop that can operate in D, T, JK, or SR modes. The 3.3 V core is paired with a flexible I/O ring that supports per-pin voltage tolerance and PCI-compliant drive strengths in the A-grade variant. Typical applications include bus-interface bridging, address decoding, glue logic for ASIC/FPGA designs, power-up sequencing controllers, and legacy 5V system integration. The PLCC-44 footprint also makes it attractive for industrial control boards and retrofits where through-hole or socketed programmable logic is preferred over fine-pitch BGAs. Compared with microcontrollers, the EPM3032A executes combinational decisions in a single 4.5 ns propagation delay, eliminating firmware overhead and the latency of interrupt-driven code. When designing with this part, allocate JTAG pins (TDI, TDO, TMS, TCK) for in-system programming and boundary-scan test. Reserve the dedicated input pin GCLK1 for high-fanout global clock distribution, and use the GCLRn pin for asynchronous global clear. The PLCC socket allows easy firmware updates during prototyping; in production, choose the -10N speed grade (commercial 0C to +70C) or migrate to the -10I industrial grade for -40C to +85C operation.

The Intel / Altera EPM3032ALC44-10 is a member of the MAX 3000A family of high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs) built on the Altera MAX architecture. The device provides 32 macrocells, 2 logic array blocks (LABs), 34 user I/O pins, a 10 ns pin-to-pin propagation delay, and is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC, J-Lead) package. The EPM3032ALC44-10 operates from a 3.3 V supply and offers in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and FPGAs in the programmable logic hierarchy: PAL/GAL -> CPLD -> FPGA. CPLDs use EEPROM or flash configuration memory, providing instant-on behavior at power-up with no external boot PROM, and offer deterministic timing with predictable pin-to-pin delays - making them ideal for glue-logic, interface bridging, and control-plane functions rather than high-density data-path processing. Key features of the EPM3032ALC44-10 include 600 usable gates, an internal counter frequency of up to 227.3 MHz, 3.3 V ISP via JTAG compliant with IEEE Std. 1532, multi-vendor concurrent programming support, and built-in JTAG boundary-scan test. The device operates across the commercial 0C to +70C temperature range and is offered in a surface-mount 44-PLCC J-lead package for socketed or hand-soldered prototype applications. The MAX 3000A architecture implements a classic AND-OR plane feeding a programmable macrocell array, where each macrocell contains a flip-flop with configurable clock/clear options. Logic is implemented through a programmable interconnect array (PIA) that provides deterministic, fixed-delay routing - this is why CPLD timing is specified as a simple pin-to-pin number (10 ns here) rather than the statistical Fmax used for FPGAs. Typical applications include bus-interface bridging (e.g., 8-bit MCU to 16-bit peripheral), address decoding, power-up sequencing logic, configurable peripheral glue logic in industrial controllers, and JTAG-driven board-level test infrastructure. The 44-PLCC package is also socket-friendly, which simplifies laboratory prototyping and field replacement. Design consideration: a single 3.3 V rail is sufficient - no separate core/IO supply is required. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of each VCC pin, and provide a JTAG header for in-system programming. Compared with the EPM3032ATC44-10 variant, this -10 speed grade offers the slowest timing margin, which is acceptable for control-plane logic running below 50 MHz.

The Altera EPM3032ALC44-10N is a 32-macrocell, 600-gate CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with a 10 ns pin-to-pin propagation delay. It operates from a 3.3 V core supply and supports in-system programmability (ISP) via the built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface, while the ISP circuitry itself complies with the IEEE Std. 1532 concurrent-programming specification. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PAL/GAL-style macrocell arrays on a single chip with a programmable interconnect matrix. CPLDs sit between small PAL/GAL SPLDs and larger FPGAs in the programmable logic hierarchy: low-power, deterministic timing, and zero-configuration boot make them ideal for glue logic, bus interfacing, and control-plane state machines. The MAX architecture used in the EPM3032A family places logic into Logic Array Blocks (LABs), each containing multiple macrocells with configurable product-term logic and flip-flops. The EPM3032ALC44-10N integrates 2 Logic Array Blocks hosting 32 macrocells total, exposes 34 user I/O pins, and delivers an internal fMAX around 103.1 MHz at the 10 ns speed grade. MultiVolt I/O allows the I/O bank to interface with 1.8 V, 2.5 V, 3.3 V and 5.0 V mixed-voltage systems without external level shifters, which simplifies board design when bridging legacy peripherals to modern ASICs. Built-in boundary-scan (BST) circuitry supports IEEE 1149.1 manufacturing test and on-board JTAG programming. From an architectural standpoint, the MAX 3000A device uses an EEPROM-based configuration cell that retains the bitstream without external boot memory, so the device is functional within microseconds of power-up. The non-volatile cell also enables 100% CMOS compatibility with low standby current and supports 100 erase/program cycles for in-field updates via JTAG. Typical applications include industrial control glue logic, address decoding and bus interfacing on legacy PCI/ISA backplanes, power-up reset sequencing, state-machine control for motor drives, LED and seven-segment display multiplexing, and portable / battery-powered devices that benefit from instant-on, low standby power logic integration. Designers should consider the 3.3 V VCCINT requirement and ensure bulk decoupling (typically 0.1 uF + 10 uF) is placed adjacent to the PLCC power pins; unused I/O pins should be left floating or tied to VCCIO through a resistor to avoid floating-input oscillation.

The Altera EPM3032ALC44-7 is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, delivering 600 usable system gates, 32 macrocells, and 34 user I/O pins in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with J-lead surface-mount terminations. It operates from a single 3.3 V supply and provides in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, enabling board-level configuration and boundary-scan test without removing the device from the circuit. The "-7" speed grade corresponds to a 7.5 ns pin-to-pin logic delay (tPD1) and a maximum operating frequency of 138.9 MHz, which makes it suitable for glue-logic, interface bridging, and state-machine applications that require deterministic sub-10 ns response. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/PLAs and large FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA. Unlike SRAM-based FPGAs, CPLDs use on-chip EEPROM or flash to store configuration, so they power up instantly without an external boot PROM. The MAX 3000A architecture is organized into Logic Array Blocks (LABs) interconnected by a programmable interconnect array (PIA); each macrocell contains a product-term AND/OR array plus a programmable flip-flop. This product-term architecture gives CPLDs their signature deterministic timing and predictable fan-out delay, which is why CPLDs remain preferred for address decoding, bus arbitration, and reset distribution. Key features of the EPM3032ALC44-7 include 32 macrocells across 2 LABs, 34 usable I/O pins, 2 global clock networks, 3.3 V core and I/O supply with 5.0 V tolerant I/O pins, JTAG (IEEE 1149.1) ISP, open-drain or programmable pull-up I/O options, and a commercial 0 to 70 °C operating temperature grade. The MAX 3000A family supports MultiVolt I/O that can interface with 5.0 V, 3.3 V, and 2.5 V logic without level shifters, simplifying mixed-voltage designs. Typical applications include address decoding and chip-select generation in microprocessor and microcontroller systems, bus arbitration logic for PCI, ISA, and VME backplanes, glue-logic consolidation that replaces multiple 74-series TTL/CMOS gates, state-machine controllers for peripherals and motor drives, and reset / watchdog sequencing for multi-rail power systems. The 7.5 ns propagation delay supports synchronous designs up to roughly 60 MHz externally and 138.9 MHz fMAX internally. When designing with this part, reserve one of the four JTAG pins (TDI, TDO, TMS, TCK) in your schematic even if in-system programming is not used in production - these pins must not be left floating, or the JTAG state machine may latch into an undefined state. Place a 0.1 µF decoupling capacitor within 5 mm of each VCC pin and a bulk 10 µF tantalum capacitor near the supply entry point. Unused I/O pins should be left floating; do not externally pull them up or down, as this can conflict with the JTAG boundary-scan pull-ups during programming.

The Altera (Intel) EPM3032ALC44-7N is a 32-macrocell, 7.5 ns pin-to-pin delay member of the MAX 3000A family of Complex Programmable Logic Devices (CPLDs), housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. It provides 600 usable gates, in-system programmability via IEEE 1149.1 JTAG, and operates from a 3.0 V to 3.6 V single supply. The -7 speed grade corresponds to a 7.5 ns maximum propagation delay (tPD1) and a 227.3 MHz maximum internal counter frequency (fCNT), making it suitable for glue-logic, address decoding, bus interfacing, and state-machine replacement tasks in 3.3 V digital systems. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a programmable interconnect matrix. CPLDs sit in the programmable logic hierarchy between simple SPLDs (PALs/GALs) and higher-density FPGAs; they offer deterministic timing, instant-on operation from on-chip EEPROM/Flash, and typically 32 to 512 macrocells. The MAX 3000A family is one of Altera's classic 3.3 V CPLD lines, predating the later MAX II/MAX V families, and is widely used as a low-density "glue logic" replacement for multiple discrete 74LS/74HC TTL parts. Key features include 32 macrocells, 34 usable I/O pins (out of 44 total package pins), 4 dedicated inputs, in-system programmability through the built-in JTAG (IEEE Std 1149.1) interface, and a MultiVolt core that allows the I/O banks to interface with 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage devices. The device is fabricated on a CMOS EEPROM process, ensuring 100 program/erase cycles of reprogrammability and zero standby power retention. The 44-pin J-lead PLCC package gives a robust through-hole-style socket mount compatible with production programming sockets. The MAX 3000A architecture uses a Logic Array Block (LAB) of 16 macrocells with a Programmable Interconnect Array (PIA) that provides deterministic, predictable timing — a 7.5 ns tPD is guaranteed regardless of routing density. Each macrocell contains a programmable AND/OR array with a configurable flip-flop that can emulate D, T, JK, or SR flip-flops. This deterministic timing and instant-on non-volatile configuration distinguish CPLDs from SRAM-based FPGAs in applications where boot-time predictability is critical. Typical applications include 3.3 V glue-logic replacement for multiple 74-series TTL gates, address decoding for microprocessors and DSPs, bus arbitration logic in microcontroller systems, power-up sequencing controllers, LED display multiplexing drivers, and state-machine controllers in industrial control boards. The wide MultiVolt I/O also makes the EPM3032ALC44-7N useful as a level shifter between 5 V peripherals and 3.3 V cores. When designing with this device, plan for one JTAG chain entry point (TCK/TMS/TDI/TDO plus TRST) for ISP, and connect all unused I/O pins to defined logic levels (GND or VCCIO) to minimize quiescent current. Use Altera's Quartus II design software (or MAX+PLUS II for legacy projects) for design entry, fitting, and JEDEC file generation.

The device operates from a 3.3 V core supply and supports MultiVolt I/O, allowing the I/O banks to interface with 5.0 V, 3.3 V, and 2.5 V logic levels. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single chip with a central interconnect, providing glue-logic, interface-bridging, and bus-decoding functions in digital systems. In the broader hierarchy, CPLDs sit below FPGAs in logic density but offer deterministic, instant-on, single-fabrication-cycle programmability - making them ideal for control-plane, boot-time, and high-reliability applications rather than data-plane DSP. The MAX 3000A family was one of the most widely adopted 3.3 V CPLD lines of its era. Key features include 3.3 V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, full PCI-SIG compliance (Revision 2.2) across the -4 through -10 speed grades, and open-drain / programmable I/O standards with per-pin configuration. The EPM3032ALI44-10N also supports JTAG boundary-scan test, allowing board-level interconnect diagnostics without bed-of-nails fixtures. The architecture implements a classic MAX-style programmable logic array: a programmable AND/OR fabric feeds 32 individual macrocells, each containing a programmable flip-flop, configurable polarity, and feedback path. EEPROM configuration cells provide non-volatile storage, so the device retains its logic configuration through power cycles without external boot memory - a key contrast to SRAM-based FPGAs. Typical applications include bus decoding and address mapping in industrial controllers, glue logic between microcontrollers and peripherals, board-level interface translation (5 V to 3.3 V / 2.5 V), and PCI bridge designs. Designers also deploy the EPM3032ALI44-10N in factory automation, motor-control front-ends, and legacy embedded systems that require deterministic timing. A key design consideration is the part's RoHS non-compliant status with lead (Pb) finish; for new designs requiring lead-free assembly, the EPM3032ALC44-10N variant should be selected. Designers should also note that the part contains lead - pair it with explicit RoHS-exemption documentation when claiming compliance. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing an actionable reference for both new designs and legacy system maintenance.

EPM3032ATC-44-10N - MAX 3000A CPLD, 32 Macrocells, 44-TQFP | Intel

The Intel (formerly Altera) EPM3032ATC-44-10N is a member of the MAX 3000A family of Complex Programmable Logic Devices (CPLDs), delivering 600 usable gates, 32 macrocells, and 34 user I/O pins in a 44-pin TQFP package. It operates from a 3.3 V supply and provides pin-to-pin delays as fast as 10 ns with counter frequencies reaching 103.1 MHz, making it suitable for glue-logic, interface bridging, and state-machine replacement tasks in cost-sensitive designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip with a programmable interconnect matrix. Architecturally, CPLDs sit between simple SPLDs (like 22V10 PALs) and larger FPGAs, offering deterministic timing, instant-on operation, and high-drive I/O without external configuration memory. The MAX 3000A family is part of the broader programmable logic IC hierarchy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Key features include In-System Programmability (ISP) compliant with IEEE Std. 1532, MultiVolt I/O supporting 1.8 V, 2.5 V, and 3.3 V interfaces, bus-friendly architecture with programmable slew-rate control, and an open-drain output option per pin for wired-OR control signaling. A programmable security bit protects proprietary designs, and a power-saving mode reduces macrocell current by more than 50% during idle periods. The device is fabricated on EEPROM-based CMOS technology, giving it instant-on behavior without external boot memory. Each macrocell contains a programmable AND/OR array with a configurable flip-flop, and the interconnect fabric provides uniform, deterministic delays across all 32 logic blocks - a key advantage over FPGAs for control-plane applications where timing predictability matters more than raw logic density. Typical applications include address decoding and bus interfacing in microcontroller systems, glue logic between ASICs and processors, configuration registers for FPGAs, motor control state machines, and general-purpose I/O expansion. The commercial (0C to +70C) operating range suits indoor and consumer electronics, while the 44-pin TQFP package enables compact PCB layouts with standard surface-mount assembly. When designing with this device, note that the -10 speed bin is the slower commercial offering; if you need higher performance, the -7 or -4 bins exist within the same family and are pin-compatible drop-in upgrades. Ensure your JTAG chain includes the 4-wire ISP header (TCK, TMS, TDI, TDO plus VCC/GND) for in-field reprogrammability.

EPM3032ATC44-10

EPM3032ATC44-10 - 32-Macrocell 10ns CPLD 3.3V TQFP-44 | Altera

The Altera (now Intel) EPM3032ATC44-10 is a 32-macrocell, 600-gate CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, supplied in a 44-pin TQFP (Thin Quad Flat Pack) package with a 10 ns pin-to-pin propagation delay. The 'TC' suffix denotes the commercial operating temperature range, and the '-10' speed grade specifies the 10 ns tPD. The device is fabricated on advanced CMOS EEPROM technology and operates from a single 3.3 V supply (3.0 V to 3.6 V), delivering counter frequencies up to 227.3 MHz and supporting in-system programmability (ISP) through the built-in IEEE 1149.1 JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays interconnected by a programmable switch matrix. The MAX 3000A family sits between simple SPLDs/GALs and larger FPGAs, offering deterministic 10 ns timing, instant-on EEPROM configuration, and 100% tested fixed propagation delays. The 32 macrocells are organized into 2 Logic Array Blocks (LABs), each providing 16 macrocells with product-term logic, a programmable flip-flop, and fast I/O feedback. Key features include 34 user I/O pins, 600 usable gates, 10 ns maximum propagation delay, 4.5 ns global setup time, 227.3 MHz maximum internal frequency, JTAG boundary-scan test support, and multiVolt I/O for interfacing with 2.5 V, 3.3 V, or 5.0 V logic. The CMOS EEPROM process provides 100 erase/program cycles per reprogrammable cell, and the IEEE 1149.1 (JTAG) port enables in-system programming without removing the device from the PCB. The MAX architecture uses a uniform interconnect scheme in which every LAB connects to every other LAB through a single global FastTrack interconnect, eliminating routing bottlenecks and delivering the predictable 10 ns timing regardless of design placement. The 2.5 V internal core voltage (derived from an internal regulator) reduces dynamic power compared with 5 V CPLDs, while the multiVolt I/O pins can be driven from 1.8 V to 5.0 V sources. Typical applications include bus interface glue logic, address decoding, state-machine controllers, power-up sequencing, peripheral chip-select generation in 8051/ARM-based embedded boards, industrial control boards requiring instant-on non-volatile logic, JTAG-driven boundary-scan test chains, and pin-compatible logic replacement for legacy 22V10/16V8 SPLDs in upgrade paths. The 0 to 70°C commercial temperature range suits consumer, office, and industrial-instrumentation equipment. Design consideration: use the Altera MAX+PLUS II or Quartus II design tools to compile VHDL/Verilog/Schematic designs; verify that pin assignments respect the JTAG TMS/TCK/TDI/TDO dedicated pins (typically 27/30/28/29 on the 44-pin TQFP). Note that the MAX 3000A family has been moved to NRND/EOL status by Intel PSG — verify long-term availability before new designs.

EPM3032ATC44-10AA - 32-Macrocell 3.3V CPLD, 10ns, 44-TQFP | Intel

The Intel (formerly Altera) EPM3032ATC44-10AA is a 32-macrocell, 34-I/O Complex Programmable Logic Device (CPLD) from the MAX 3000A family, offering 600 usable gates, 10 ns pin-to-pin propagation delay, and 3.3 V in-system programmability through the IEEE Std. 1149.1 JTAG interface in a 44-pin TQFP package. The -10 speed grade provides a maximum propagation delay of 10 ns and counter frequencies up to 227.3 MHz, while the 'A' suffix denotes the 3.3 V core supply and the 'C' denotes the commercial 0C to +70C operating temperature range. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks with a centralized interconnect matrix. CPLDs sit in the programmable logic hierarchy between simple SPLDs (PAL/GAL) and large FPGAs; they offer instant-on (zero-configuration) behavior, deterministic timing, and high-drive I/O. The MAX 3000A family uses EEPROM configuration cells, eliminating the need for external boot memory and supporting multi-vendor ISP per IEEE Std. 1532. Key features include 32 macrocells across 2 logic array blocks (LABs), 34 user I/O pins, 3.3 V core supply (VCCINT) with selectable 2.5 V/3.3 V/5.0 V I/O supply (VCCIO), an IEEE Std. 1149.1 JTAG boundary-scan test interface, and built-in ISP compliance per IEEE Std. 1532. The MAX architecture delivers predictable timing because routing paths through the programmable interconnect array (PIA) have fixed delays that do not depend on user logic placement. The MAX 3000A architecture employs a classic AND-OR-XOR macrocell with a product-term allocator, shared logic expanders, and a per-macrocell flip-flop with programmable clear, preset, and clock options. The EEPROM-based configuration is one-time programmable per logic cell, with ISP re-programmability through JTAG. The I/O structure is split: VCCINT powers the core and input buffers, VCCIO powers the output drivers, allowing mixed-voltage interfacing without external level shifters. The 44-pin TQFP package provides a compact 10 mm x 10 mm footprint for surface-mount designs. Typical applications include glue-logic integration in industrial controllers, address decoding and bus interfacing in embedded systems, state-machine replacement in motor control, I/O expansion for legacy microcontrollers, and JTAG-configured bus bridges. The instant-on behavior is valuable in safety-critical and deterministic-latency paths where FPGA configuration time is unacceptable. When designing with this part, observe the dual-supply requirement: VCCINT must be 3.3 V, while VCCIO can be tied to 2.5 V, 3.3 V, or 5.0 V depending on the interface voltage of the connected devices. Decouple both rails locally with 0.1 F and 10 F capacitors.

EPM3032ATC44-10N

EPM3032ATC44-10N - MAX 3000A CPLD, 32 Macro, 10ns | Intel

The Intel (formerly Altera) EPM3032ATC44-10N is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, packaged in a 44-pin TQFP. It integrates 600 usable gates, 32 macrocells, 2 Logic Array Blocks (LABs), and 34 user I/O pins, with a pin-to-pin logic delay of 10 ns and internal counter frequencies up to 138.9 MHz at a 3.3 V core supply. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the programmable logic hierarchy between simple SPLDs (PAL/GAL) and FPGAs. CPLDs use a classic AND/OR macrocell fabric backed by EEPROM or flash configuration memory, providing instant-on behavior, deterministic timing, and excellent pin-to-pin delay guarantees that make them ideal for glue logic, bus interfacing, and control-plane decoding where FPGAs are over-specified and discrete logic is too large. Key features of the EPM3032ATC44-10N include 3.3-V in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface, MultiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V logic levels, optional open-drain outputs on every I/O for wired-OR control signaling, and IEEE Std. 1532 compliant ISP for concurrent multi-vendor programming. The device operates over the commercial 0 C to +70 C range (the trailing -10 speed grade corresponds to 10 ns tPD). Internally, the MAX 3000A architecture uses the Logic Element (LE) as its fundamental building block, organized into LABs that share a programmable interconnect array (PIA). Each macrocell contains a programmable AND/OR array, a flipflop, and configurable output enable, giving designers deterministic combinatorial plus registered logic with predictable 10 ns timing regardless of routing complexity. Typical applications include address decoding and bus interface bridging, power-up and power-sequencing controllers, state-machine controllers for industrial and consumer peripherals, peripheral chip select generation for microprocessors, and high-speed glue logic on PC/104, VME, and PCI add-in boards where instant-on EEPROM-based logic avoids the configuration delay of an FPGA. Designers should ensure that all I/O banks are powered within the supported MultiVolt range and that the JTAG chain (TCK, TMS, TDI, TDO) is correctly terminated for in-system programming. Decoupling the 3.3 V VCCINT pin with 0.1 uF and 10 uF capacitors close to the package minimizes core-noise-induced timing jitter on high-frequency paths.
