Typical Applications
EPM7128AET1100-7 is suitable for 6 applications: Legacy Industrial 5V Glue Logic, Address Decoding & Bus Interfacing, Peripheral Controllers in Telecom & Test Equipment, State Machine & Protocol Bridging, 5V-Tolerant I/O Expansion, Power Sequencing & Reset Logic.
Legacy Industrial 5V Glue Logic
The EPM7128AET1100-7 is a drop-in for legacy 74-series glue logic on 5V industrial control boards, where its 128 macrocells and 84 user I/Os replace dozens of discrete 74HC/74FCT gates. The device runs natively on a 5.0V VCC rail with 3.3V-5V tolerant I/O, eliminating the need for level shifters when interfacing with legacy 5V microcontrollers, bus transceivers, and ASICs. Its EEPROM-based non-volatile configuration gives instant-on behaviour at power-up with no external boot PROM, simplifying board design and reducing BOM cost. The -7 speed grade provides 5ns pin-to-pin delay, well within typical address decoding and bus arbitration windows. Industrial temperature rating (-40C to +85C) makes it suitable for factory automation, motor control, and process control environments.
Recommended
Address Decoding & Bus Interfacing
The EPM7128AET1100-7 is widely used for address decoding and bus interfacing on 5V microcontroller and microprocessor boards. Its 128 macrocells can generate multiple chip-select windows across a 16- or 24-bit address bus with 5ns propagation delay, suitable for synchronous memories, peripherals, and dual-port RAM. The 84 user I/Os accommodate simultaneous data bus steering, chip-select generation, and interrupt prioritization. Each macrocell supports both combinatorial and registered outputs, enabling registered chip-select signals with predictable timing. JTAG in-system programming allows late-stage board customization and field firmware upgrades without removing the device, ideal for industrial controls and test equipment with evolving peripheral sets.
Recommended
Peripheral Controllers in Telecom & Test Equipment
In telecom and test equipment designs, the EPM7128AET1100-7 serves as a peripheral controller handling time-critical I/O expansion, watchdog logic, and protocol glue between processors and ASICs. Its 5V tolerance matches legacy line-card designs, while JTAG boundary-scan (IEEE 1149.1) enables board-level interconnect test. The non-volatile EEPROM eliminates the need for a separate boot device, and the four dedicated global clock/clear inputs simplify synchronous state machine design. The TQFP-100 package supports reflow-compatible lead-free assembly per JEDEC J-STD-020 MSL-3, meeting modern manufacturing requirements. With 128 macrocells, designers can integrate multiple peripheral interfaces (UART glue, SPI/I2C bridging, custom timing) into a single device.
Recommended
State Machine & Protocol Bridging
The EPM7128AET1100-7 implements custom state machines and protocol bridges (e.g., parallel-to-serial converters, I2C/SPI muxing, custom peripheral controllers) with deterministic 5ns timing. Each of its 128 macrocells can be configured as a D/T/JK flip-flop with separate clear and clock, enabling complex FSMs without external glue. The PIA interconnect routes signals across LABs with uniform delay, simplifying timing closure. Per-macrocell power reduction is available for unused sections, useful in battery-backed industrial instrumentation. Designers targeting 5V rails can preserve legacy ASIC compatibility while consolidating multiple SSI/MSI packages into one CPLD, reducing board area and improving reliability.
Recommended
5V-Tolerant I/O Expansion
Modern 3.3V ASICs and FPGAs often lack sufficient 5V-tolerant I/O for legacy peripherals; the EPM7128AET1100-7 fills this gap by providing 84 5V-tolerant I/Os that level-shift and isolate signals between modern 3.3V cores and 5V peripheral devices. Its JTAG interface allows easy field reprogramming to adapt to evolving peripheral mixes without board respins. The 5ns pin-to-pin delay is fast enough to interpose transparently in most peripheral buses. The industrial temperature rating and 5V supply make it ideal for retrofitting 5V I/O into modern 3.3V-centric designs in industrial automation, automotive test equipment, and instrumentation.
Recommended
Power Sequencing & Reset Logic
The EPM7128AET1100-7 provides deterministic power-sequencing logic for multi-rail systems by generating delayed reset, power-good, and enable signals with precise timing. Its four dedicated global clock/clear inputs can be driven from external supervisory rails, allowing clean synchronization to system events. The EEPROM configuration ensures the same sequence at every power-up - critical for FPGAs, ASICs, and DSPs that require specific rail order. With 128 macrocells, designers can implement watchdog timers, brown-out detectors, and fault-handling logic alongside simple sequencing. The TQFP-100 package fits standard 5V industrial layouts.

Key Differentiators
- Native 5V supply voltage (vs EPM570T100C5N (MAX II family))
- Larger macrocell count for higher density designs (vs EPM7128AELC84-10N (84-pin PLCC, same die))
- Faster -7 speed grade than the L (low-cost) variants (vs EPM7128AELC84-10N (-10N speed grade))
- Cross-vendor CPLD alternative with 128 macrocells (vs XC2C128-7VQG100C (Xilinx CoolRunner-II))
Design Notes
Estimated: The EPM7128AET1100-7 draws up to 300 mA (typical ICC ~80-150 mA depending on logic utilization and toggle rate) from a 5.0V VCC rail. Place one 0.1 uF X7R ceramic decoupling capacitor within 5mm of every VCC/GND pair on the TQFP-100 package, plus a bulk 10 uF tantalum or aluminum-polymer capacitor near the supply entry point. Use a star-ground topology tying GND pins directly to a low-impedance ground plane to minimize SSO noise.
TQFP-100 has 0.5 mm pitch leads - use 0.15 mm/0.20 mm trace-and-space rules and a 4-layer PCB with continuous ground plane for signal integrity. Fan out from the package perimeter, not under the body. Keep JTAG TCK/TMS/TDO/TDI traces short (<50 mm) and away from switching I/O. Match clock trace lengths to within 5 mm if multiple clock domains are used. Exposed thermal pad (if present on the package variant) must be soldered to the ground plane for thermal dissipation.
Do not confuse EPM7128AET (industrial, -40C to +85C) with EPM7128AETC (commercial, 0C to +70C) - they share part number prefix but differ in temperature grade. Ensure the JTAG chain order matches the BSDL file pin order; misordered chains cause programming failures. Do not exceed 5.5V on any VCC pin or 5.5V on any I/O pin (VCCIO absolute maximum). Observe MSL-3 floor life of 168 hours at <30C/60% RH after bag opening before reflow. For new designs, prefer the active MAX V 5M240ZE64C5N over the last-time-buy EPM7128AET1100-7.
When interfacing the EPM7128AET1100-7 with 3.3V logic, confirm VCCIO is in the 3.3V-5V tolerance range. Use series resistors (22-33 ohm) on high-speed clock outputs to dampen reflections, and keep stub lengths under 5 mm. Avoid running I/O traces parallel to clock traces for more than 25 mm; use orthogonal crossings or ground-plane shielding for critical signals. The PIA interconnect imposes uniform routing delay across LABs - register outputs at the macrocell flip-flop for predictable timing closure at high toggle rates.
Place the JTAG connector or test header at the board edge for probe access. Route TCK with a 10 kohm pull-up to VCC at the device end to prevent floating-clock programming glitches. If the design uses in-system programming (ISP), include the ByteBlaster II header footprint even if programming is performed once at production - field firmware updates are common. Reserve a 4-pin header (TCK, TMS, TDO, TDI plus GND) and keep it unpopulated in volume builds if not used.
Compliance Information
