EPM3128ATC100-5 개요
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks interconnected by a programmable switch matrix. CPLDs sit between simple SPLDs and FPGAs in the programmable logic hierarchy - they offer deterministic timing (fixed pin-to-pin delays), instant-on operation from EEPROM configuration memory, and higher logic density than discrete PAL/GAL devices while consuming less power and providing more predictable timing than most FPGAs. The MAX architecture integrates logic array blocks (LABs), an interconnect matrix, I/O control blocks, and the in-system programming engine into a single CMOS die.
Key features of the EPM3128ATC100-5 include 2,500 usable gates, 80 programmable I/O pins (each configurable as input, output, or bidirectional), four dedicated input pins, a global clear signal, and output drivers programmable for 2.5 V or 3.3 V while all inputs are 2.5 V, 3.3 V, and 5.0 V tolerant. The device supports JTAG boundary-scan testing per IEEE Std. 1149.1, has programmable security bits for design protection, and provides a typical counter frequency of 192.3 MHz. The commercial temperature grade spans 0 °C to 70 °C, and the TQFP-100 package offers a low-profile surface-mount footprint suited to high-density PCB designs.
Typical applications for the EPM3128ATC100-5 include bus interface bridging (e.g., PCI-to-ISA glue logic), address decoding and chip-select generation, state-machine and sequencer implementation, I/O expansion and level translation between 5 V and 3.3 V domains, and glue-logic replacement of discrete 74-series TTL parts. It is widely used in industrial controllers, telecom base-station control boards, and legacy design refreshes where deterministic timing, instant-on behavior, and in-field reprogrammability are required.
When designing with this device, allocate sufficient decoupling (0.1 µF per supply pin), observe the IEEE 1149.1 JTAG chain if multiple devices share the bus, and confirm Quartus II / MAX+PLUS II software support for the -5 speed grade. The 'A' suffix denotes the enhanced MAX 3000A family; the -5 suffix indicates the 7.5 ns (or 5 ns commercial) speed grade, which is the slowest of the MAX 3000A speed grades.

일반적인 애플리케이션
EPM3128ATC100-5 적합 용도: 6 애플리케이션s: Bus Interface Bridging and Glue Logic, Address Decoding and Chip-Select Generation, State Machines and Sequencer Implementation, Mixed-Voltage Level Translation (5 V to 3.3 V), Legacy 74-Series TTL Replacement, Industrial Control and Factory Automation.
Bus Interface Bridging and Glue Logic
The EPM3128ATC100-5 is widely used as glue logic between microprocessors, memory, and peripheral buses in industrial and embedded designs. With 128 macrocells and 80 user I/Os, the device can implement address decoders, chip-select generators, wait-state controllers, and bus mux/demux functions in a single chip. Its 5 ns pin-to-pin delay meets the timing budget for PCI, ISA, and VMEbus bridges, where deterministic timing is essential. Compared to discrete 74-series TTL parts, it consumes less board area, reduces BOM cost, and is in-system reprogrammable for late-stage design changes.
추천
Address Decoding and Chip-Select Generation
The MAX 3000A architecture is optimized for wide AND-OR decode trees, making the EPM3128ATC100-5 ideal for address decoding in memory-mapped systems. The 128 macrocells can implement dozens of independent chip-select signals with full address-range decoding, even across 32-bit address buses. The 5 ns tPD ensures the chip-select assertion occurs well within one memory-access cycle. Designers typically program the device once via JTAG, then store the configuration in non-volatile EEPROM that loads instantly on power-up, with no boot delay.
추천
State Machines and Sequencer Implementation
Each EPM3128ATC100-5 macrocell contains a flip-flop programmable as D, T, JK, or SR with independent clock, clear, and preset controls. This makes the device excellent for implementing complex multi-state controllers such as motor-control state machines, communication protocol sequencers, and FPGA configuration controllers. With 192.3 MHz counter frequency and deterministic timing, the CPLD can drive high-bandwidth sequencing logic at full system clock rates. Designers can iterate state diagrams in MAX+PLUS II or Quartus II and reprogram in-circuit via JTAG.
추천
Mixed-Voltage Level Translation (5 V to 3.3 V)
The EPM3128ATC100-5 input pins accept 2.5 V, 3.3 V, and 5.0 V signals, while outputs are programmable to 2.5 V or 3.3 V. This allows the device to act as a bidirectional level translator between legacy 5 V peripherals and modern 3.3 V ASICs, microcontrollers, or FPGAs without external level-shifters. Up to 80 channels of translation can be implemented in a single device. The 5 ns propagation delay preserves timing margins in high-speed interfaces such as parallel ADC/DAC links, GPIO expansion buses, and legacy peripheral interconnects.
추천
Legacy 74-Series TTL Replacement
The EPM3128ATC100-5 can absorb the function of dozens of 74LS, 74HC, and 74FTC logic gates into a single device, dramatically reducing PCB area, power consumption, and assembly cost. With 128 macrocells, the device typically replaces 20-50 equivalent discrete SSI/MSI packages. Designers can drop in the CPLD with no changes to the board's signal routing - the same TQFP-100 footprint replaces a forest of SOIC packages. JTAG programming lets engineering teams refine logic without board respins.
추천
Industrial Control and Factory Automation
With its 80 user I/Os, deterministic 5 ns timing, and proven MAX 3000A architecture, the EPM3128ATC100-5 is found in PLC digital I/O modules, motor-drive interface boards, and process-control instruments. While the commercial-temperature grade (0 °C to 70 °C) limits it to controlled environments, the pin-compatible EPM3128ATC100-10N extends operation to industrial -40 °C to +85 °C. The CPLD handles encoder decoding, PWM generation, optocoupler interface, and emergency-stop logic in a single reprogrammable device, simplifying compliance with IEC 61131-2 industrial control standards.

설계 노트
Estimated: the EPM3128ATC100-5 draws approximately 35-55 mA quiescent ICC at 3.3 V on VCCINT plus additional I/O VCCIO current proportional to switching frequency and load. Decouple each VCCINT and VCCIO pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the supply pin. Add a bulk 10 µF tantalum or low-ESR ceramic near the device. The MAX 3000A family does not require power sequencing between VCCINT and VCCIO, but simultaneous ramp-up is recommended. In standby (no switching), the device draws under 5 mA - useful for battery-backed designs.
Use a 4-layer PCB with dedicated ground and power planes for designs exceeding 50 MHz internal frequencies. Route JTAG signals (TDI, TDO, TMS, TCK) with 4-6 mil traces and keep them away from fast-switching I/O. Add 4.7 kΩ pull-ups on TMS and TDI to keep the JTAG state machine in a known state during power-up. Locate the device close to the JTAG header to minimize stub length; chained JTAG devices should share a common TCK with TDI/TDO daisy-chained. Keep I/O traces short (under 50 mm) for signals above 50 MHz to avoid reflections.
Three pitfalls are common when migrating the MAX 3000A design: (1) Quartus II dropped MAX 3000A support after v13.0 SP1 - if the original design file is unavailable, a fresh MAX+PLUS II license and legacy toolchain are required; (2) the ISP programming voltage is generated internally from VCC - external 12 V VPP is NOT required (unlike older MAX 5000/7000 devices); (3) the 'A' suffix (MAX 3000A) is NOT pin-compatible with the original MAX 3000 - the older MAX 3000 outputs were 5 V TTL, while MAX 3000A outputs are 2.5 V/3.3 V CMOS - replacing one with the other requires recompilation. Always verify the BSDL file matches the exact part number before JTAG boundary-scan testing.
Estimated: the TQFP-100 package has a typical θJA of approximately 45-55 °C/W (exact value depends on PCB copper area and airflow). With commercial 0-70 °C ambient and worst-case ICC of 150 mA, internal dissipation is roughly 0.5 W, giving a junction temperature rise of 22-28 °C above ambient - well within the 125 °C maximum. For industrial temperature variants (EPM3128ATC100-10N), ambient up to 85 °C is acceptable with similar copper area. No heatsink is required under any normal operating condition; however, the thermal performance improves dramatically with larger ground-plane copper on the top and bottom layers under the package.
규정 준수 정보
EPM3128ATC100-5 (non-N suffix) is the standard lead-bearing variant - NOT RoHS compliant. The EPM3128ATC100-5N suffix variant is the lead-free RoHS-compliant assembly of the same silicon. REACH, halogen-free, and conflict-mineral declarations are not present in the verified web data - all marked unknown.
