EPM7128EQC100-10 Visão geral
A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PAL-like macrocell arrays interconnected by a programmable interconnect matrix. CPLDs sit in the broader hierarchy of programmable logic devices (CPLD -> PLD -> programmable logic -> digital semiconductor), offering deterministic timing, low power, and glue-logic integration that historically replaced dozens of 74-series TTL parts on a single chip.
Key features include a 100 MHz internal performance, 5.0 V CMOS core technology with 4.75 V to 5.25 V supply range, in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, and a commercial 0 °C to 90 °C operating temperature range. The device is built on a second-generation MAX architecture with four Logic Array Blocks (LABs) and a global interconnect that delivers fixed, predictable propagation delays regardless of routing.
The EPM7128EQC100-10 architecture combines 128 macrocells grouped into four LABs of 16 macrocells each, with a Programmable Interconnect Array (PIA) that routes signals globally. Each macrocell contains a programmable AND/OR array plus a configurable flip-flop, supporting both combinational and registered logic with deterministic 10 ns tpd and 100 MHz fCNT performance.
Typical applications include bus interface bridging (e.g., 8-bit/16-bit microcontroller glue logic), address decoding and chip-select generation in embedded systems, peripheral control and timer/counter replacement, and legacy 74-series TTL integration. The MAX 7000 family is widely used in industrial controllers, telecommunications line cards, and test equipment where instant-on non-volatile configuration and deterministic timing are required.
When designing with this part, ensure the JTAG chain respects the TCK-to-TDI/TDO timing specified in the MAX 7000 datasheet family, and provide a clean 5 V supply with adequate bulk decoupling. Note that this part is now in Intel's legacy portfolio and lifecycle should be confirmed before new designs.
This page synthesizes distributor pricing, drop-in alternatives from the same MAX 7000 family, and practical design notes not found in the manufacturer datasheet alone - useful for engineers maintaining legacy hardware or sourcing hard-to-find programmable logic.

Aplicações típicas
EPM7128EQC100-10 é adequado para 6 aplicaçãos: Microcontroller Bus Interface Bridging, Address Decoding and Chip-Select Generation, Legacy 74-Series TTL Integration, Industrial Control and PLC Logic, Telecommunications Line-Card Glue Logic, Test and Measurement Equipment Front-End.
Microcontroller Bus Interface Bridging
The EPM7128EQC100-10's 84 user I/O pins and 10 ns deterministic tpd make it well suited to bridging between microcontrollers and peripherals with mismatched bus widths or timing. With 128 macrocells across four LABs, it can implement multiple address-latch, chip-select, and wait-state generators in a single chip. The 5 V tolerant I/O directly interfaces with legacy 8051, 68HC11, and similar MCU buses without level shifters, and the deterministic timing allows reliable glue logic replacement of dozens of 74-series TTL packages.
Recomendado
Address Decoding and Chip-Select Generation
The EPM7128EQC100-10 is widely used as an address decoder in 8/16/32-bit embedded systems, where it generates chip-selects for memory banks and peripherals from a single address bus. The 128 macrocells easily accommodate full 24-bit address decoding with multiple chip-enable outputs, while the 10 ns propagation delay ensures CS-valid timing is met before memory access windows close. Non-volatile EEPROM configuration means no boot PROM is required, simplifying BOM and reducing board space compared to discrete decoder PALs.
Recomendado
Legacy 74-Series TTL Integration
The EPM7128EQC100-10 was historically used to replace entire boards of 74LS/74HC glue logic - latches, multiplexers, decoders, shifters, and state machines - with a single non-volatile device. The MAX 7000 macrocell structure maps directly onto classic AND-OR PLA patterns, easing migration of legacy TTL schematics. With 2,500 usable gates and 84 I/Os, a single EPM7128EQC100-10 typically replaces 10-20 discrete packages, reducing PCB area and improving long-term availability of obsolete TTL parts.
Recomendado
Industrial Control and PLC Logic
The EPM7128EQC100-10's commercial 0-90 °C operating range, 5 V supply tolerance, and instant-on non-volatile configuration make it suitable for industrial control boards and PLC peripheral modules. The deterministic 10 ns timing supports hard-real-time control loops where predictability outweighs raw speed. Industrial designers value the JTAG ISP path for field firmware updates, and the PQFP-100 package's surface-mount compatibility supports modern SMT assembly lines for medium-volume control products.
Recomendado
Telecommunications Line-Card Glue Logic
In telecom line cards and access equipment, the EPM7128EQC100-10 provides deterministic timing for E1/T1 framers, HDLC controllers, and time-slot interchangers. The 128 macrocells handle multiple independent functions - alarm generation, loop-back control, and LED status multiplexing - with the 10 ns delay fitting comfortably within standard telecom timing budgets. The 5 V tolerant I/Os interface directly with legacy telecom ASICs, and the non-volatile configuration eliminates boot-time variability critical for carrier-grade equipment.
Recomendado
Test and Measurement Equipment Front-End
Test instruments such as logic analyzers, protocol testers, and bench-top emulators use the EPM7128EQC100-10 for pattern generation, channel multiplexing, and trigger sequencing. The 100 MHz internal performance supports fast pattern rates while the deterministic tpd simplifies timing analysis in test setups. With 84 I/Os available, multiple test channels can be routed through a single device, and the JTAG interface enables easy firmware updates as test protocols evolve during product development.

Notas de projeto
Estimated: The EPM7128EQC100-10 typically draws ~50-150 mA quiescent current at 5 V depending on output switching activity. Provide at least one 0.1 µF ceramic decoupling capacitor adjacent to each VCC/GND pair (the PQFP-100 has 3 VCC and 3 GND pins spread around the package) plus a single bulk 10 µF tantalum or low-ESR electrolytic cap on the supply rail. Estimated input values used: VCC = 5.0 V, ICC = 100 mA typical, decoupling per MAX 7000 datasheet recommendations.
PQFP-100 packages require careful thermal and signal-integrity layout. Use a 4-layer PCB with a dedicated ground plane under the device to provide the low-impedance return path for the high-edge-rate I/O drivers. Route JTAG signals (TCK, TMS, TDI, TDO) as a short chain with series damping near the connector; the JTAG chain is sensitive to reflections and ground bounce. Keep clock inputs away from high-slew-rate outputs to avoid coupling into LAB sense amplifiers.
Estimated: When programming in-system via JTAG, ensure VCC is stable and within 4.75-5.25 V before asserting TCK - programming below this threshold can corrupt the EEPROM configuration. Always issue a JTAG bulk-erase before re-programming a part from an unknown source, and verify the IDCODE via Quartus before write operations. Estimated input: standard JTAG programming voltage 5.0 V, threshold per MAX 7000 datasheet ISP specification. Note that this part is obsolete - validate the JTAG chain with a known-good device before relying on it for production programming.
The EPM7128EQC100-10 in PQFP-100 has a typical theta-JA of around 50 °C/W (per MAX 7000 family datasheet). For commercial 0-90 °C operation at moderate switching activity, no heatsink is required. For sustained high-activity designs (e.g., continuously clocked counters), verify junction temperature using the EPM7128 power calculator - the I/O drive strength contributes significant dynamic power that scales with toggle rate.
Informações de conformidade
RoHS/REACH/lead-free status not explicitly listed in verified distributor data for this obsolete part. Original MAX 7000 family parts from this era are typically non-RoHS - the 'N' suffix variants (e.g. EPM7128AETC100-10N) are the lead-free / RoHS-friendly alternatives from the same family.
