EPM3128ATI144-5N Ringkasan

The Altera (now Intel Programmable Solutions Group) EPM3128ATI144-5N is a 128-macrocell, 2,500-gate Complex Programmable Logic Device (CPLD) from the MAX 3000A family, packaged in a 144-pin TQFP and qualified for industrial temperature operation. It delivers 192.3 MHz maximum operating frequency with a 5.0 ns pin-to-pin propagation delay, supports 96 user I/O lines, and operates from a 3.3 V core supply with 3.0 V to 3.6 V tolerance. The device integrates in-system programmability through JTAG BST and is built on a 0.30 um CMOS EEPROM process.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-on programmable logic IC that combines multiple PAL-style macrocell arrays on a single die with a central interconnect matrix. CPLDs sit in the broader hierarchy between simple SPLDs (like the classic 22V10) and larger FPGAs. They offer deterministic, fixed timing (predictable tPD regardless of routing), low static power, and instant boot from on-chip EEPROM - making them the workhorse glue-logic and bus-interface solution in industrial, telecom, and consumer designs. The MAX 3000A family is Altera's classic 3.3 V EEPROM-based CPLD line.

Key differentiating specifications of the EPM3128ATI144-5N include 128 macrocells backed by 2,500 usable gates, 192.3 MHz fMAX with 5.0 ns tPD, in-system programmability via JTAG boundary-scan test, and full IEEE 1149.1 boundary-scan support. Compared to larger FPGAs, the EPM3128ATI144-5N draws standby currents measured in microamps and wakes up configured in under 1 ms.

Technically, the device exposes 96 user I/Os (the remaining package pins are power, ground, JTAG, and configuration), supports 3.3 V LVCMOS/LVTTL I/O with 5.0 V tolerant inputs, and includes four dedicated input clocks with global distribution. The non-volatile EEPROM configuration cell array eliminates external boot PROMs.

Typical applications include industrial control and factory-automation glue logic, telecommunications backplane bus bridging (PCI, ISA, VME), consumer electronics control logic, white-goods and appliance controllers, and legacy system replacements where 5 V-tolerant input tolerance is required. Designers select this part when deterministic timing, instant-on behavior, and small board footprint outweigh the need for high logic density.

When designing with the EPM3128ATI144-5N, observe the 3.0 V to 3.6 V supply rail tolerance and decouple each VCCIO/VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin. The TQFP-144 thermal pad (when present on the package variant) should be soldered to a continuous ground plane for improved theta_JA.
