EPM570T100C4N Ringkasan

The Intel (formerly Altera) EPM570T100C4N is a MAX II family Complex Programmable Logic Device (CPLD) delivering 570 logic elements and 440 macrocells in a 100-pin TQFP (14x14 mm) package. Built on a 0.18 µm non-volatile flash process, it offers up to 76 user I/O, 247.5 MHz internal performance, and 5.4 ns pin-to-pin propagation delay, providing instant-on non-volatile configuration with single-chip glue-logic density well above legacy 5V CPLDs.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single die with a global interconnect fabric. It sits in the programmable logic hierarchy between simple SPLDs (like GAL/PAL) and high-density FPGAs (like MAX 10 or Cyclone), making it ideal for I/O expansion, bus bridging, power-sequencing logic, and high-drive control where deterministic timing and instant-on boot are mandatory. The MAX II family specifically targets low-power, low-cost glue-logic replacement with on-chip flash storage that eliminates an external configuration PROM.

Key features include 8 Kbits of user flash memory, an on-chip voltage regulator (single 3.3 V supply with internal generation of 1.8 V core), JTAG-based IEEE 1149.1 in-system programmability, 4-input look-up tables, and a MultiVolt I/O bank that supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces on the same die. The flash-based configuration memory removes the boot-delay penalty of SRAM FPGAs and is fully re-programmable in-circuit.

Technically, the EPM570T100C4N implements a Logic Array Block (LAB) architecture of 570 LEs distributed across 19 LABs, with each macrocell containing a programmable register, product-term logic, and I/O control. The non-volatile flash cell array achieves zero boot latency, enabling the device to drive outputs within microseconds of power-up. The 100-pin TQFP (T4 suffix = commercial 0 °C to 85 °C, speed grade 4 = 5.4 ns tpd) variant exposes 76 user I/Os and is footprint-compatible with EPM570T100C3N/C5N speed and density siblings.

Typical applications include I/O expansion and bus bridging in industrial controllers, power-sequencing and supervisory logic in networking equipment, glue logic in telecom backplanes, motor-control and LED-driving interfaces, and legacy 5V CPLD replacement in telecom/medical designs. The instant-on non-volatile configuration is particularly valued in deterministic boot systems such as automotive clusters, building automation, and safety-critical industrial controls.

Design considerations include placing the 0.1 µF + 1 µF decoupling capacitors as close as possible to every VCCINT/VCCIO pin pair, providing a clean 3.3 V rail (the internal regulator rejects to 1.8 V core), and verifying the MultiVolt bank voltage (VCCIO) matches the driven interface before any configuration bitstream is loaded. Designers should also confirm the 100-pin TQFP thermal envelope supports their continuous-junction loading before relying on it in enclosed industrial housings.
