EPM570GT144I5N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL splatter logic and high-density FPGAs. It is built from multiple macrocell Logic Array Blocks (LABs) interconnected by a global programmable interconnect matrix, retains configuration in on-chip flash, and provides deterministic, nanosecond-class pin-to-pin propagation delays. Within the broader taxonomy, a CPLD is a type of programmable logic device -> logic IC -> integrated circuit, frequently used as glue logic, I/O expansion, or interface bridging in micro-controller-based systems.
Key features of the EPM570GT144I5N include 8 Kbits of on-chip User Flash Memory (UFM), MultiVolt core and I/O for mixed-voltage rails, instant-on non-volatile flash configuration, enhanced in-system programmability (ISP) via JTAG, and 116 user I/O pins (TQFP-144). The device is fabricated on a 6-layer-metal flash process and offers high I/O count, fast propagation delay, and reliable fitting versus alternative CPLD architectures.
The MAX II architecture uses a Lookup Table (LUT)-based LAB array with non-volatile flash configuration cells, eliminating the external boot PROM required by SRAM-based FPGAs and providing instant-on behavior within microseconds of power-up. The MultiVolt I/O bank design lets a single 1.8 V core part directly interface with 1.5 V, 1.8 V, 2.5 V, and 3.3 V peripherals without external level shifters.
Typical applications include industrial control glue logic, bus interface bridging (e.g., parallel-to-SPI, address latch decoding), power-up sequencing and reset distribution, I/O expansion for microcontrollers, and LED / 7-segment display multiplexing. The 116-user-I/O count is well suited to systems that need many general-purpose pins but lack the bulk of an FPGA.
When designing with this part, reserve JTAG pins (TDI, TMS, TCK, TDO) for ISP programming and boundary-scan test; they cannot be repurposed as user I/O. For mixed-voltage designs, consult the I/O standard tables in the datasheet to select the correct VCCIO bank voltage; incorrect bank voltage is the most common EPM570 design error.

Typical Applications
EPM570GT144I5N is suitable for 6 applications: Industrial Glue Logic & Bus Decoding, I/O Expansion & Interface Bridging, Power-Up Sequencing & Reset Distribution, LED Display Multiplexing & Scanning, Legacy Parallel Bus Interfacing, Custom Peripheral Implementation in Test & Measurement.
Industrial Glue Logic & Bus Decoding
The EPM570GT144I5N's 570 LE capacity and 116 user I/O make it well-suited as a high-density glue-logic CPLD in industrial control boards where multiple address-latch, chip-select, and interrupt-routing signals must be combined. Its MultiVolt I/O bank design lets the 1.8 V core interface directly with 3.3 V microcontrollers and 5 V-tolerant peripherals without external level shifters. The non-volatile instant-on configuration means deterministic startup sequencing within microseconds of power-up, which is critical in PLC and motor-control systems that demand deterministic reset behavior. Quartus II place-and-route fits typical bus-decoder logic in tens of LEs, leaving the majority of the device free for additional glue functions.
Recommended
I/O Expansion & Interface Bridging
The EPM570GT144I5N functions as an I/O expander for microcontrollers with insufficient pin count, particularly in human-machine-interface (HMI) and panel-meter designs. The 116 user I/O can be partitioned into multiple banks at different voltages (1.5 V, 1.8 V, 2.5 V, 3.3 V), bridging a low-voltage MCU to legacy 3.3 V or 2.5 V peripherals. Its 8 Kbit User Flash Memory (UFM) stores non-volatile configuration data such as calibration constants, model IDs, or serial numbers, accessible through an internal interface. Compared with discrete I/O expander chips, the CPLD delivers parallel multi-pin updates in a single clock and supports custom serial protocols (SPI, I2C, UART) implemented in hardware.
Recommended
Power-Up Sequencing & Reset Distribution
The EPM570GT144I5N's non-volatile flash configuration and instant-on behavior make it ideal for power-up sequencing in multi-rail systems. A small state machine inside the CPLD asserts each downstream regulator's enable pin in the correct order with user-defined delays, ensuring processors, FPGAs, and analog circuits power up in their required sequence. The device's deterministic propagation delay (around 5.4 ns pin-to-pin in I5 speed grade) keeps timing margins tight. Its 1.8 V core draws only tens of milliamps, so it can be powered directly from a small always-on rail, while its MultiVolt I/O banks drive 3.3 V or 2.5 V enable lines to the main regulators.
Recommended
LED Display Multiplexing & Scanning
The EPM570GT144I5N's 116 user I/O and fast I5-grade propagation delay make it well-suited for driving multiplexed LED matrices, 7-segment displays, or scanned keypads in industrial HMIs and large signage panels. Its LUT-based LABs can implement scan counters, row/column decoders, PWM dimmers, and Charlieplexing logic with sub-10 ns pin-to-pin delay, eliminating display flicker at high refresh rates. The MultiVolt I/O banks interface directly with 3.3 V LED driver ICs or 5 V tolerant logic without level shifters. The 8 Kbit User Flash Memory stores pattern tables, font glyphs, or brightness curves that the logic engine reads during refresh cycles.
Recommended
Legacy Parallel Bus Interfacing
The EPM570GT144I5N is commonly used to bridge legacy 8-bit, 16-bit, or 32-bit parallel buses (such as PC/104, ISA, or custom microcontroller buses) to modern SPI, I2C, or QSPI peripherals in industrial retrofit designs. Its MultiVolt I/O banks let a single CPLD translate between a 5 V-tolerant legacy bus and a 1.8 V modern peripheral without external buffers. The 116 user I/O easily accommodates data, address, chip-select, and read/write control signals for a 16-bit bus plus auxiliary logic. The flash-based non-volatile configuration preserves bus-translation behavior across power cycles with no boot delay.
Recommended
Custom Peripheral Implementation in Test & Measurement
In test and measurement equipment, the EPM570GT144I5N implements custom stimulus-response, pattern generation, or signal-conditioning peripherals that cannot be addressed with off-the-shelf ICs. Its 570 LE capacity fits pattern generators, PRBS (pseudo-random binary sequence) generators, or trigger logic, while the 8 Kbit User Flash Memory stores test vectors or calibration data. The fast I5 speed grade (around 5.4 ns pin-to-pin) and high I/O count support parallel test-pin architectures with deterministic timing. The JTAG ISP interface allows field reprogramming of test patterns without removing the CPLD from the board.

Design Notes
Reserve the JTAG pins TDI, TMS, TCK, and TDO for ISP programming and IEEE 1149.1 boundary-scan; they cannot be repurposed as user I/O on the EPM570GT144I5N. Route the JTAG chain with short, parallel traces and a 4.7 kohm pull-up on TCK to ground to avoid noise-induced programming failures. If JTAG is unused in production, at minimum tie TCK low to prevent floating-clock configuration writes.
Estimated: the EPM570GT144I5N draws approximately 30-50 mA from the 1.8 V VCCINT rail in typical designs (per MAX II datasheet DC characteristics). Decouple VCCINT with one 1 uF X7R ceramic plus one 0.1 uF X7R ceramic placed within 5 mm of the supply pins. Each VCCIO bank (1.5 V / 1.8 V / 2.5 V / 3.3 V) requires its own 0.1 uF + 1 uF decoupling pair, and the GND pins must all be connected to a continuous ground plane for return-current integrity.
The most common EPM570 design error is configuring a MultiVolt I/O bank for the wrong voltage. Each I/O bank on the EPM570GT144I5N has its own VCCIO pin; an I/O pin assigned to a 3.3 V bank will be damaged if the bank is powered at 1.8 V, and a 1.8 V output driving a 3.3 V input will not meet VIH. Cross-check bank assignments in the Quartus II Pin Planner before generating the programming file.
For high-speed signals (>50 MHz) on the EPM570GT144I5N, use 50 ohm controlled-impedance traces and place series-termination resistors close to the CPLD output. The I5 speed grade supports around 5.4 ns pin-to-pin delay; signal integrity, not propagation delay, is typically the bottleneck above 100 MHz. Avoid stub traces and keep JTAG and clock traces away from switching I/O to reduce ground-bounce coupling.
