EPM3128ATC100-10NS نمای کلی

The Intel EPM3128ATC100-10NS is a member of the MAX 3000A family of Complex Programmable Logic Devices (CPLDs), offering 128 macro cells and 80 user I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package with 10 ns pin-to-pin logic delay. It operates from a 3.3 V core supply and supports MultiVolt I/O, which allows its I/O banks to interface with 5.0 V, 3.3 V, or 2.5 V logic levels by powering VCCIO at the appropriate rail. The device provides in-system programmability (ISP) compliant with IEEE Std. 1532, enabling concurrent programming across multiple PLD vendors.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macro-cell arrays with a programmable interconnect matrix. It sits between simple logic gates and FPGAs in the programmable logic hierarchy and is widely used for glue logic, bus interfacing, state-machine control, and power-up sequencing in digital systems. The MAX 3000A family belongs to Intel's (formerly Altera's) classic CPLD portfolio, providing instant-on, deterministic timing, and high pin-to-pin speed that FPGAs cannot match for small, fast, fixed-function blocks.

Key features of the EPM3128ATC100-10NS include 4.5 ns pin-to-pin logic delays with counter frequencies up to 227.3 MHz, programmable interconnect that allows any pin to drive any macro cell or I/O, and JTAG-based boundary-scan testing per IEEE 1149.1. The 80 available I/O pins (out of 100 total package pins) share 4 dedicated input clocks and a global clear network, while 3.3 V core operation keeps power dissipation low for industrial and consumer applications.

Architecturally, the device uses EEPROM-based configuration cells, providing non-volatile storage that retains the logic design without external memory. The MAX 3000A macro cells implement sum-of-products logic with configurable flip-flops and a wide fan-in AND-OR structure, while the interconnect matrix (the so-called "Programmable Interconnect Array" or PIA) routes signals between logic array blocks with predictable timing.

Typical applications include bus-interface bridging, address decoding and chip-select generation, state-machine and sequencer implementation, power-up and reset sequencing, peripheral I/O expansion, and glue-logic replacement of discrete 74-series TTL. Its 5 V-tolerant I/O and fast propagation delay also suit industrial control and motor-drive front ends.

When designing with this device, ensure VCCINT is a regulated 3.3 V and VCCIO is set according to the I/O logic level. Decoupling must include 0.1 uF and 1 uF capacitors placed within 5 mm of each supply pin. JTAG chain order should be planned before PCB layout to avoid re-spinning the board for testability.
