EPM3032ALC44-4N 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile, flash/EEPROM-backed programmable logic device used to implement glue logic, interface bridging, bus decoding, and state-machine control in digital systems. The MAX 3000A family sits in the hierarchy below FPGAs in terms of logic density but above discrete 74-series logic in terms of integration and design flexibility, making it ideal for low-density, deterministic logic replacement where instant-on non-volatile configuration is required.
Key features of the EPM3032ALC44-4N include 600 usable gates, 2 Logic Array Blocks (LABs), in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, and ISP compliance with IEEE Std. 1532 for multi-vendor concurrent programming. The MultiVolt I/O architecture uses separate VCCINT (internal/3.3 V) and VCCIO (I/O driver) pins, allowing mixed-voltage interfacing with 5.0-V, 3.3-V, or 2.5-V peripherals on the same die without external level shifters.
The MAX 3000A architecture combines a programmable interconnect array with EEPROM-backed macrocells, providing non-volatile configuration that retains state across power cycles without an external boot PROM. The 4.5-ns tPD (pin-to-pin delay) and 227.3 MHz fCNT translate to deterministic timing suitable for asynchronous logic replacement, address decoding, and high-speed control plane tasks in telecom, industrial, and computing systems.
Typical applications include peripheral bus interfacing (PCI, ISA, and proprietary buses), address decoding for memory and I/O subsystems, state-machine implementation for ASIC/FPGA replacement, power-up sequencing control, and JTAG-based board-level testing. Designers frequently select the EPM3032ALC44-4N when a small, deterministic, non-volatile logic block is needed in a legacy 44-pin PLCC footprint.
When designing with this device, ensure proper decoupling on VCCINT and VCCIO rails and confirm JTAG chain termination per IEEE 1149.1. The 4.5-ns speed grade is best chosen when the design requires maximum counter frequency; the slower -7, -10, or -15 grades in the same package offer cost savings for less timing-critical logic.

主な用途
EPM3032ALC44-4N の用途: 6 件s: Address Decoding & Bus Interface Logic, ASIC/FPGA Glue Logic Replacement, State Machine & Control Plane Implementation, Peripheral Chip Select & Memory Interleaving, JTAG Chain & Boundary-Scan Controller, Industrial Control & Legacy System Modernization.
Address Decoding & Bus Interface Logic
The EPM3032ALC44-4N is well suited for address decoding and bus-interface glue logic in legacy microprocessor and microcontroller systems. Its 32 macrocells can implement multiple chip-select decoders, wait-state generators, and interrupt controllers in a single non-volatile device, replacing dozens of 74-series TTL gates. The 4.5-ns pin-to-pin delay and 227.3 MHz counter frequency give designers comfortable timing margin for 33 MHz PCI, ISA bus, or 50 MHz local-bus applications. Unlike an FPGA, the EEPROM-backed configuration retains state across power cycles, so no external boot PROM is needed. The MultiVolt I/O (2.5/3.3/5.0 V on VCCIO) lets the part drive 5-V TTL peripherals directly while the core runs at 3.3 V - ideal for mixed-voltage retrofits of legacy designs that still use 44-PLCC sockets.
おすすめ
ASIC/FPGA Glue Logic Replacement
The EPM3032ALC44-4N is frequently used as glue logic around ASICs, ASSPs, microprocessors, and FPGAs that need deterministic, non-volatile control signals. Typical uses include power-up sequencing, reset distribution, clock-divider generation, and chip-select steering. The 32-macrocell capacity is enough to absorb 5-10 small state machines plus several decode blocks, while the 4.5-ns tPD ensures setup/hold margins are met even with skewed backplane traces. Because the device programs over JTAG (IEEE 1149.1) and is IEEE 1532 compliant, design revisions can be field-upgraded without removing the part from the board. The 44-PLCC J-lead package is also socket-compatible with legacy 44-PLCC footprints, allowing drop-in upgrade of older programmable-logic sockets.
おすすめ
State Machine & Control Plane Implementation
The EPM3032ALC44-4N implements complex state machines for control-plane tasks in industrial, telecom, and embedded systems. With 32 macrocells split across 2 LABs and 34 user I/Os, it can host multiple concurrent FSMs handling protocol conversion, handshaking, and watchdog logic. The 227.3 MHz fCNT rating supports fast timer/counter peripherals, while the deterministic 4.5-ns tPD makes timing closure tractable without complex static-timing-analysis flows. Designers benefit from EEPROM non-volatility: state survives brown-outs and cold boots without an external configuration memory, simplifying board layout. The IEEE 1149.1 JTAG and IEEE 1532 ISP also enable boundary-scan testing at the board level, improving manufacturability for volume production.
おすすめ
Peripheral Chip Select & Memory Interleaving
The EPM3032ALC44-4N is a strong fit for generating peripheral chip-selects and memory-interleave control signals in microcontroller- or DSP-based boards. Its 32 macrocells comfortably implement multi-bank memory decoding, byte-enable steering, and bank-switch logic for SRAM, DRAM, or flash arrays. The 4.5-ns tPD keeps decode latency below one 33 MHz PCI clock or two 50 MHz bus clocks, and the 34 I/O pins can drive up to 17 chip-select lines with complementary enables. The MultiVolt I/O interface means the part can drive 5-V peripheral logic directly from a 3.3-V VCCINT core, eliminating external level shifters on legacy expansion buses. EEPROM non-volatility also lets designs retain boot-time chip-select maps without a configuration ROM.
おすすめ
JTAG Chain & Boundary-Scan Controller
The EPM3032ALC44-4N can act as a simple JTAG chain manager or boundary-scan controller in multi-device boards, leveraging its built-in IEEE 1149.1 TAP and IEEE 1532 ISP compliance. The device's 34 I/O pins can be assigned to TCK, TMS, TDI, TDO routing, plus auxiliary TAP control signals, allowing it to coordinate programming and test access for downstream CPLDs, FPGAs, or boundary-scanable peripherals. The 4.5-ns tPD supports TCK frequencies above 50 MHz for production programming throughput, and the non-volatile EEPROM configuration means the JTAG topology is locked at power-up with no boot sequence. The 44-PLCC footprint also suits legacy board designs that already allocate a small PLCC site for a test-access controller.
おすすめ
Industrial Control & Legacy System Modernization
The EPM3032ALC44-4N supports industrial control and legacy system modernization by replacing obsolete discrete TTL or bipolar PLD logic with a single non-volatile CPLD. Its 600 usable gates and 34 I/Os can absorb entire decoder/sequencer sub-systems from retired 74F/74AS designs, reducing PCB area, BOM count, and power consumption. The 3.3-V core with MultiVolt 5-V-tolerant I/O allows direct interface to legacy 5-V industrial busses without glue logic, and the J-lead 44-PLCC package is footprint-compatible with older 44-PLCC sockets for retrofit boards. Combined with IEEE 1149.1 JTAG and IEEE 1532 ISP, field upgrades can be performed without desoldering, minimizing downtime in installed industrial equipment.

設計ノート
The EPM3032ALC44-4N requires two separate supply rails: VCCINT at 3.3 V for the core and logic, and VCCIO at 2.5 V, 3.3 V, or 5.0 V for the I/O drivers. Estimated: typical ICCINT at 227 MHz fCNT is on the order of tens of mA; place a 0.1 uF decoupling capacitor within 5 mm of each VCCINT/VCCIO pin and a bulk 10 uF tantalum or ceramic near the package to suppress switching transients during ISP programming cycles. Never leave VCCIO floating - the I/O pins default to undefined behavior without a valid VCCIO.
The 44-pin PLCC J-lead package has 1.27 mm (50 mil) lead pitch and a 16.6 mm x 16.6 mm body. Use a socket (e.g., 3M 8444-21B1-RK-TD) if field reprogrammability or quick swap-out is needed; otherwise solder directly to a PCB land pattern matching JEDEC PLCC-44. Keep JTAG traces (TCK, TMS, TDI, TDO) short and matched within 25 mm to preserve signal integrity at high TCK frequencies - Estimated: trace length mismatch above ~50 ps can cause TAP state-machine errors above 25 MHz TCK.
Do not confuse speed-grade suffixes: '-4' is the fastest (4.5 ns tPD), followed by '-7', '-10', '-12', and '-15'. The 'A' prefix (e.g., EPM3032A-TC44-10N) denotes the MAX 3000A revision, not a different family - it is still pin-compatible with EPM3032-prefix parts in the same package. Do not connect any user I/O pin directly to VCCINT or VCCIO without a series resistor if the pin will be configured as an input during ISP, as the JTAG ISP engine drives those pins momentarily. Always verify the Quartus/MAX+PLUS II BSDL file matches the package suffix before generating boundary-scan tests.
Place the EPM3032ALC44-4N close to the devices it glues together - keep decode outputs under 50 mm to avoid reflections, and route clock inputs with a 22-33 ohm series-termination resistor if fCNT approaches 200 MHz. The GND pins (10, 22, 31) should each connect to a low-impedance ground plane via short vias; do not daisy-chain GND. For JTAG chain designs, place a 10 kohm pull-up on TCK, TMS, and TDI to keep the TAP in a benign state during board power-up per IEEE 1149.1 recommendations.
コンプライアンス情報
RoHS/REACH/lead-free status not stated in the provided datasheet excerpt. The 'N' suffix in Altera/Intel ordering nomenclature historically indicates Pb-free termination, but this must be confirmed against the latest Intel material declaration (MDDS) before production use.
