EPM3512AQC208-10NS Ringkasan

The Altera (now Intel) EPM3512AQC208-10NS is a 512-macro-cell, 172-I/O CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, housed in a 208-pin PQFP (Plastic Quad Flat Pack) package and specified at the -10 (10 ns) speed grade. Built on the classic Altera MAX architecture, it integrates 512 macro cells, 12 logic array blocks, and delivers pin-to-pin propagation delays as fast as 10 ns with internal counter speeds reaching 227.3 MHz. Operating from a single 3.3 V core supply with selectable 2.5 V/3.3 V/5.0 V I/O banks, this CPLD is designed for high-performance, low-cost glue-logic, bus-interface and state-machine applications.

A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PAL-like macro-cell blocks with a central interconnect matrix. Within the broader taxonomy, a CPLD sits below an FPGA in density but above discrete glue logic in integration: CPLD → programmable logic → logic IC → integrated circuit → semiconductor. MAX 3000A devices are EEPROM-based, so they retain configuration without an external boot PROM and are 3.3 V in-system programmable via the IEEE Std. 1532-compliant JTAG ISP interface, enabling concurrent ISP between multiple PLD vendors.

Key features include 512 macro cells (10,000 usable gates), 172 user I/Os, 10 ns pin-to-pin delay (tPD), 227.3 MHz internal counter frequency, MultiVolt I/O supporting 2.5 V/3.3 V/5.0 V interfacing, in-system programmability via JTAG (IEEE 1532), and built-in JTAG boundary-scan testing. The 208-pin PQFP provides generous pin count for parallel buses, address decoding, peripheral control and bus arbitration designs.

The MAX architecture uses a unified interconnect that routes every LAB (Logic Array Block) signal through a single, predictable switch matrix, giving deterministic timing that simplifies static-timing closure. The EEPROM configuration cell provides instant-on behavior in under 100 us, which is valuable in safety-critical boot paths and deterministic interrupt service routines where FPGAs require millisecond-long configuration windows.

Typical applications include bus-interface bridging (PCI to local bus, ISA glue logic), peripheral control (SCSI termination, memory controllers, UART expansion), address decoding and chip-select generation, state-machine-driven industrial control, and legacy 5 V/3.3 V system logic replacement. Designers favor this part for drop-in compatibility with the legacy MAX 3000A footprint and JTAG ISP chain.

When designing with this device, observe the VCCINT/VCCIO separation (3.3 V core, optional 2.5 V/3.3 V/5.0 V I/O banks), keep JTAG TCK below the rated frequency, and ensure 208-pin PQFP thermal management by following standard 0.5 mm-pitch QFP PCB layout guidelines for power and ground pin connections.
