EPM3128ATC100-10 جائزہ

The Intel / Altera (formerly Altera) EPM3128ATC100-10 is a member of the MAX 3000A family of CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs), delivering 128 macrocells, 80 user I/Os, and a 10 ns pin-to-pin propagation delay in a 100-pin TQFP package. It operates from a 3.3 V core supply with MultiVolt I/O that is compatible with 5.0 V, 3.3 V, and 2.5 V logic levels, enabling drop-in interfacing with mixed-voltage buses and legacy TTL parts.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip with a programmable interconnect matrix. CPLDs sit in the programmable logic hierarchy between simple PLDs (PAL/GAL) and FPGAs, offering instant-on behavior, deterministic timing, and EEPROM-based configuration that retains bitstream without external boot memory. The MAX 3000A family specifically targets glue-logic, bus-interface, and PCI-compliant bridge applications where low cost, predictable timing, and in-system programmability (ISP) outweigh the need for FPGA-class logic density.

Key features of the EPM3128ATC100-10 include in-system programmability compliant with IEEE Std. 1532 for concurrent ISP across vendors, MultiVolt I/O (5.0 V / 3.3 V / 2.5 V tolerant), PCI-SIG-compliant timing for local-bus interfacing, and a 100-pin TQFP footprint with 80 usable I/Os. The non-volatile EEPROM configuration cell eliminates the need for external configuration memory and provides instant-on operation at power-up.

Architecturally, the device uses Altera's classic MAX architecture with Logic Array Blocks (LABs), a programmable interconnect array (PIA), and per-macrocell flip-flops with selectable clear/preset and clock options. The 3.3 V core and 5 V-tolerant I/Os are fabricated on a CMOS EEPROM process that supports ISP through the JTAG (IEEE 1149.1 / IEEE 1532) interface. Counter frequencies reach 227.3 MHz, and the pin-to-pin delay of 10 ns in this speed grade suits state-machine and address-decoding tasks.

Typical applications include PCI bus interface glue logic, address decoding and chip-select generation in embedded systems, glue logic between microprocessors and peripherals, bus-width translation between 5 V MCUs and 3.3 V peripherals, and power-up sequencing logic in industrial controllers. The wide MultiVolt I/O range and PCI-compliant timing make it especially attractive for legacy industrial designs migrating between logic families.

When designing with this part, ensure that input signals conform to the I/O standard's VCCIO rail and observe the JTAG (IEEE 1149.1) tap connection requirements for ISP. Note that the EPM3128ATC100-10 is a mature, mature-lifecycle device suitable for long-life programs but typically sourced through authorized distributors due to limited active manufacturing.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single source for selection, replacement, and lifecycle context.
