EPM3128ATC144-5 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell arrays on a single die, connected through a programmable interconnect matrix. The MAX 3000A family belongs to the broader hierarchy: CPLD -> programmable logic device (PLD) -> logic IC -> semiconductor. CPLDs are typically chosen over FPGAs for glue-logic, bus-interface, state-machine, and power-up deterministic applications because their EEPROM configuration cells boot in microseconds, not milliseconds, and retain state without external boot memory.
Key features include 128 macrocells arranged in 8 logic array blocks (LABs), 250 usable I/O pins within the package (with 96 user I/Os exposed externally per the 144-pin TQFP), two global clock networks with clear and clock-enable control on every register, programmable interconnect, JTAG boundary-scan testing, and built-in IEEE 1149.1 (JTAG) support. The -5 speed grade corresponds to a 7.5 ns pin-to-pin propagation delay (tPD), supporting designs with up to 192.3 MHz internal counter performance. Power consumption is typically 130 mA at 3.3 V, with standby current as low as 5 mA.
The architecture is built on 0.30 um CMOS EEPROM technology with four layers of metal interconnect, exposing the user to a deterministic timing model. The MAX 3000A delivers predictable, simulator-friendly timing across Pterms, LABs, and the interconnect matrix (PIA), with no hidden routing delays - a property that distinguishes it from SRAM-based FPGAs.
Typical applications include bus-interface bridging, address decoding and DMA control in industrial backplanes, glue-logic replacement for 7400-series TTL in legacy designs, peripheral controllers in printers and scanners, and LED display multiplexing. Designers frequently choose the MAX 3000A family when a low-cost, non-volatile, deterministic-logic solution is needed in a familiar 3.3 V ecosystem.
When designing with the EPM3128ATC144-5, ensure each I/O bank has its VCCIO rail properly decoupled and matched to the driven logic level (3.3 V or 2.5 V), because mixing I/O standards in the same bank can damage the device. Provide a minimum of 0.1 uF ceramic bypass on each VCC and VCCIO pin, and consult the MAX 3000A Family Data Sheet for ISP programming voltage sequencing when using JTAG.

主な用途
EPM3128ATC144-5 の用途: 6 件s: Industrial Bus Interface Bridging, Glue-Logic Replacement for 7400-Series TTL, Printer and Scanner Peripheral Controllers, LED Display Multiplexing and Panel Drivers, Legacy Industrial Control Boards, Address Decoding and DMA Arbitration.
Industrial Bus Interface Bridging
The EPM3128ATC144-5 bridges legacy 5 V TTL peripherals to a 3.3 V microcontroller or FPGA bus, with its multi-volt I/O handling 5.0 V, 3.3 V, and 2.5 V logic on the same die. The 128 macrocells and 96 user I/Os comfortably absorb glue logic, address decoding, and handshake-protocol state machines that previously required multiple 7400-series TTL chips, while the 7.5 ns tPD keeps bus-to-bus latency negligible. Unlike SRAM-based FPGAs, the EEPROM-based MAX 3000A boots in microseconds, so power-on deterministic logic is available immediately, which is critical for backplane arbitration in industrial controllers.
おすすめ
Glue-Logic Replacement for 7400-Series TTL
Engineers use the EPM3128ATC144-5 to consolidate 7400-series discrete logic - such as 74LS138 decoders, 74LS245 transceivers, and 74LS374 registers - into a single non-volatile CPLD. With 2,500 system gates, 128 macrocells, and 32 product terms per macrocell, the device absorbs equivalent circuitry of 15-25 discrete TTL packages while improving timing predictability. The 3.3 V core with multi-volt I/O allows direct interface to both 5 V and 3.3 V devices on the same board, and the IEEE Std. 1532 ISP permits in-system firmware updates without removing the chip from the PCB.
おすすめ
Printer and Scanner Peripheral Controllers
The EPM3128ATC144-5 serves as a peripheral controller in legacy printers and document scanners, handling stepper-motor sequencing, sensor-multiplexing, and high-speed parallel-data routing between the imaging ASIC and the main processor. Its 7.5 ns tPD and 192.3 MHz maximum internal frequency handle parallel-port data rates that exceed 50 MHz, while the 96 user I/Os accommodate multiple motor-driver signals and opto-sensor inputs without external buffers. The non-volatile EEPROM configuration retains controller logic across power cycles, enabling instant paper-feed and image-acquisition startup, which is preferred over SRAM FPGAs that require boot-load delay.
おすすめ
LED Display Multiplexing and Panel Drivers
The EPM3128ATC144-5 drives large LED dot-matrix panels by time-multiplexing row/column lines and generating per-frame refresh logic, taking advantage of its 96 user I/Os and 7.5 ns tPD for flicker-free scanning rates up to 1 kHz. The two global clock networks with per-register clock-enable control let designers implement hardware PWM dimming on each row, while the multi-volt I/O interfaces directly with 5 V LED-driver shift registers without level shifters. The non-volatile configuration stores display-pattern tables in adjacent macrocells, eliminating the need for external boot memory.
おすすめ
Legacy Industrial Control Boards
The EPM3128ATC144-5 is widely deployed in legacy industrial control boards where 25-year design lifecycle support is critical, including PLC backplanes, motor-drive signal conditioning, and SCADA interface cards. Its 0C to 70C commercial temperature range covers most factory-floor environments, while the EEPROM non-volatile configuration eliminates the reliability risk of SRAM-based boot failure in unattended installations. Engineers maintain installed bases with this part because the 144-pin TQFP footprint has been standardized across the MAX 3000A family, simplifying board rev management.
おすすめ
Address Decoding and DMA Arbitration
The EPM3128ATC144-5 is used for high-speed address decoding and DMA arbitration in embedded systems, where its 7.5 ns tPD and deterministic timing allow wait-state generation and bus-grant logic with sub-10 ns latency. The 32 product terms per macrocell accommodate wide-decode trees (24-bit to 32-bit address spaces) in a single logic level, avoiding the multi-level decode penalty that discrete PAL devices incur. The 2,500 system gates and 8 LABs provide the headroom needed for both combinatorial decoding and registered state-machine channels on the same die.

主な差別化要因
- Same-die, lead-free RoHS variant for EU and global production （vs EPM3128ATC144-5 (this part, non-RoHS))
- Slower speed grade allows cost savings in non-timing-critical designs （vs EPM3128ATC144-10)
- Non-volatile EEPROM configuration boots in microseconds vs milliseconds for SRAM FPGAs （vs Cyclone-series SRAM FPGAs)
設計ノート
The EPM3128ATC144-5 requires both a 3.3 V VCC (core) rail and a separate VCCIO (I/O) rail for multi-volt I/O operation. Decouple each VCC and VCCIO pin with a 0.1 uF ceramic capacitor placed as close to the package as possible, and add a 10 uF bulk tantalum or ceramic capacitor near the device to handle ISP-induced transients. Mis-wiring VCCIO to 5 V while VCC is at 3.3 V is a common failure mode - verify bank voltages against the MAX 3000A datasheet before power-on.
Route JTAG signals (TCK, TMS, TDI, TDO) with controlled impedance and keep them away from high-speed clocks and switching I/O to avoid ISP programming failures. Place the JTAG header or connector at the edge of the PCB for production-line programming access. For 144-pin TQFP, use 0.25 mm trace width with 0.5 mm pitch escape routing to break out the inner I/O pins, and provide at least 4 ground pads on the inner ring for return-current continuity.
Do not assume that any 144-pin TQFP from the MAX 3000A family has the same pinout; the EPM3128ATC144-X, EPM3256ATC144-X, and EPM3512ATC144-X differ in pin assignments because internal LAB organization changes between density points. Also, the EPM3128ATC144-5 is not RoHS compliant per the Arrow distributor listing - do not place it on RoHS-only PCBs. Use the lead-free EPM3128ATC144-5N for EU-market products, and verify pinout against the specific device datasheet before laying out the PCB footprint.
For designs using all 96 user I/Os at 5 V TTL levels simultaneously switching, add series resistors (22-33 ohm) near the CPLD outputs to dampen transmission-line reflections on cables or long PCB traces. The MAX 3000A output drive strength is approximately 8-12 mA per pin - adequate for TTL but marginal for long cables. Use a ground-reference trace alongside each clock signal and keep clock traces under 50 mm to avoid skew.
コンプライアンス情報
