Overview

Description

The EPM7160ELI84-20 is an Altera MAX 7000S family EPLD (electrically programmable logic device). It provides a dense array of macrocells interconnected by programmable routing to implement glue logic, simple state machines, decoders, and control logic. The device comes in an 84-pin ELI package and uses a -20 speed grade (slower variant). It operates at 5V and is programmed with Altera design tools (MAX+PLUS II originally, later Quartus), typically from an external PROM or in-system programmer. Applications include interfacing microprocessors to peripherals, address decoding, timing/control logic, and other mid‑density logic functions. While powerful for its era, it is largely obsolete today and has been superseded by newer CPLDs and FPGAs. It remains relevant for legacy designs needing fixed, low-to-mid density programmable logic with relatively quick development.
