Overview

Description

EPM7256AEFI256-7 is an Altera (now Intel) MAX 7000A family CPLD (EPLD). It provides 256 macrocells and is used for small to mid-size glue logic, state machines, decoders, and I/O interfacing.
Key points
- 256 macrocells; each macrocell includes a 4-input logic function and a D-type register.
- Flexible I/O: supports registered or combinational outputs; 5V-tolerant I/O in typical 5V designs.
- Architecture suited for simple, deterministic digital logic and glue logic between components.
- Speed grade “-7” indicates its performance class; package/other specifics shown by EFI256-7 suffix.
- Programmed with legacy tools (MAX+PLUS II or early Quartus software); relies on older design flows.
Notes
- This is an older CPLD device; for new designs consider newer families (e.g., MAX 10, Cyclone/MAX 10 equivalents).
- For exact pin count, package options, I/O count, voltage ranges, and timing, consult the EPM7256A datasheet and the Intel/Altera catalog.

Features

EPM7256AEFI256-7 is a MAX 7000A EPLD. Key features:
- 256 macrocells (high-density EPLD)
- 256-pin EFI256 package
- 3.3V operation; speed grade -7 (fast)
- EEPROM-based nonvolatile configuration with in-system reprogrammability
- JTAG boundary-scan/programming interface for in-system programming and debugging
- Flexible I/O with global clocks and data distribution resources
- Suitable for complex logic, state machines, and glue logic in embedded designs
Note: As a legacy device, supported tooling is from the MAX+PLUS II era (and similar).

Package

256‑pin FineLine Quad Flat Pack (FQFP) package.

Pinout

- Pin count: 256 pins.
- Function: Altera EPM7256AEFI256-7 is a 256-pin CPLD (Complex Programmable Logic Device) from the EPM7256A family, used to implement programmable logic (macrocells) and I/O for glue logic, FSMs, decoders, and other digital interface tasks.

Manufacturer

- Manufacturer: Altera Corporation (now part of Intel).
- Kind of company: A semiconductor company that designs and manufactures programmable logic devices, specifically CPLDs and FPGAs.

Application

Common application areas for EPM7256AEFI256-7 (MAX 7000A EPLD):
- Glue logic for microprocessors/microcontrollers
- Finite-state machines and control logic
- Address decoding and timing generation
- I/O expansion and peripheral interfaces (SPI, I2C, UART, parallel)
- Bus interfacing and protocol glue; clock-domain crossing
- Data routing for consumer/industrial electronics and instrumentation

Equivalent

Closest cross references (256-macrocell CPLDs):
- Xilinx XC2C256-7 (256 macrocells, 3.3V CPLD)
- Lattice MachXO2-256 (256-macro CPLD, 3.3V)
Note: pinout, package, I/O banks, and toolchains differ—verify footprint and timing/voltage requirements before replacement.
