EPM570GT144C3N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a centralized interconnect matrix. CPLDs sit in the broader hierarchy of programmable logic devices (PLDs) -> programmable logic -> digital semiconductor ICs. MAX II CPLDs are characterized by instant-on non-volatile configuration, deterministic timing, and low static power compared to SRAM-based FPGAs, making them ideal for glue logic, interface bridging, and power-up control functions.
Key features of the EPM570GT144C3N include MultiVolt core support (1.8 V internal core with 1.5 V, 1.8 V, 2.5 V, 3.3 V I/O standards), a built-in User Flash Memory (UFM) block of 8 Kbits for configuration or data storage, JTAG IEEE 1149.1 boundary-scan support, and enhanced ISP that allows field upgrades without removing the device from the board. The 5.4 ns tPD1 propagation delay is consistent across commercial temperature ranges, providing deterministic logic timing for control paths.
Architecturally, the EPM570 organizes its 570 Logic Elements into Logic Array Blocks (LABs) interconnected by a MultiTrack interconnect, with each LE containing a 4-input look-up table (LUT) and a programmable register. The internal 1.71 V to 1.89 V core voltage is generated by an on-chip regulator, allowing the device to operate from a single 3.3 V or 2.5 V external supply while delivering MultiVolt I/O flexibility.
Typical applications include bus-interface bridging (e.g., I2C to SPI glue logic), power-up sequencing and reset distribution in multi-rail systems, LED display row/column drivers, industrial control I/O expansion, and consumer-electronics control logic where non-volatility eliminates the need for a boot configuration PROM.
When designing with this part, note that MAX II devices support vertical migration within the same TQFP-144 footprint (EPM240, EPM570, EPM1270, EPM2210), which simplifies last-minute density upgrades without board rework. Use Quartus II or the latest Intel Quartus Prime design software for synthesis, fitting, and JTAG programming.

Typical Applications
EPM570GT144C3N is suitable for 6 applications: Bus-Interface Bridge / Glue Logic, Power-Up Sequencing and Reset Distribution, Industrial Control I/O Expansion, LED Display Row/Column Driver, Consumer Electronics Control Logic, Test and Measurement Front-End.
Bus-Interface Bridge / Glue Logic
The EPM570GT144C3N is ideal for bus-interface bridging between mismatched voltage domains and protocols such as I2C to SPI, UART to parallel GPIO, or 8-bit MCU bus to 16-bit peripheral. Its 570 Logic Elements and 116 user I/Os accommodate multiple parallel bridges simultaneously, while the 8-Kbit User Flash Memory stores protocol look-up tables or device-ID configuration. MultiVolt I/O banks allow direct 3.3 V-to-1.8 V level translation without external translators. The 5.4 ns tPD1 provides deterministic latency required for handshaking protocols, and instant-on flash configuration eliminates the FPGA-style boot delay that would violate I2C/SPI timing budgets.
Recommended
Power-Up Sequencing and Reset Distribution
Multi-rail systems (FPGA + DDR + analog + I/O) require precise power-on sequencing to prevent latch-up and inrush damage. The EPM570GT144C3N's non-volatile flash configuration enables instant-on operation at the first valid rail without requiring a boot PROM, making it ideal for supervising the sequence of 4-8 power rails. Its 5.4 ns propagation delay enables glitch-free reset generation and watchdog timing, and 116 user I/Os comfortably support per-rail enable signals, power-good inputs, and fault flags. Compared to a discrete supervisory IC, the CPLD allows fully programmable timing, threshold logic, and fault-handling state machines in a single device.
Recommended
Industrial Control I/O Expansion
In PLCs, motor controllers, and industrial sensor hubs, the EPM570GT144C3N expands a small MCU's GPIO count with deterministic response to interrupts. The 570 LE fabric supports encoder quadrature decoding, PWM generation, and protocol-framing state machines, while the 116 I/Os drive 24 V industrial signal conditioning circuits via external drivers. The commercial 0-85C operating range covers most factory-floor enclosures, and the 8-Kbit UFM stores factory calibration constants or asset-tracking serial numbers. Compared to a microcontroller, the CPLD delivers sub-microsecond deterministic response critical for high-speed encoder feedback and safety interlocks.
Recommended
LED Display Row/Column Driver
Large LED video walls, stadium scoreboards, and signage displays require high-speed multiplexing of hundreds to thousands of LEDs. The EPM570GT144C3N drives 116 row/column lines directly while its 5.4 ns propagation delay supports refresh rates above 1 kHz to avoid visible flicker. The 570 LEs implement PWM dimming per channel and BCM (Binary Coded Modulation) for grayscale depth, and the 8-Kbit UFM stores gamma-correction tables or display-test patterns. Compared to discrete 74HC shift-register chains, the CPLD reduces PCB area, simplifies firmware, and enables per-pixel gamma correction in a single non-volatile device.
Recommended
Consumer Electronics Control Logic
Set-top boxes, smart appliances, and gaming peripherals need compact, low-power control logic for button matrices, IR decoders, and LED animation. The EPM570GT144C3N handles a 16x8 keypad scanner, NEC/RC5 IR protocol decode, and PWM LED breathing effects in one device. Its <100 uA standby current is critical for always-on appliances, and instant-on flash configuration means the device is ready before the main SoC finishes booting. The 570-LE capacity accommodates future feature additions without PCB redesign, and 116 I/Os support direct connection to button matrices and LED drivers without multiplexing.
Recommended
Test and Measurement Front-End
Bench instruments and ATE (Automatic Test Equipment) require programmable switch matrices, pattern generators, and timing generators with deterministic latency. The EPM570GT144C3N configures 4x4 to 16x16 FET-switch matrices for signal routing, while its 5.4 ns tPD enables precise pulse-train generation for stimulus-response testing. The 116 I/Os drive level shifters to test DUTs at multiple voltages (1.8 V / 3.3 V / 5 V), and the JTAG interface allows in-test reconfiguration to switch test patterns. Compared to dedicated ASICs, the CPLD gives the test engineer firmware-driven reconfiguration, eliminating hardware respins for new DUT families.

Design Notes
The MAX II EPM570 uses an internal voltage regulator to generate 1.8 V VCCINT from a single external 2.5 V or 3.3 V supply. According to the MAX II datasheet, decoupling requires at least four 0.1 uF ceramic capacitors placed within 5 mm of each VCCIO bank pin, plus one 10 uF bulk capacitor at the device supply pin. The internal regulator draws approximately 50-100 uA quiescent current in standby, so for ultra-low-power battery applications verify with the Quartus PowerPlay analyzer.
TQFP-144 package has a 0.5 mm pin pitch and a 20x20 mm body. Route all signals on inner PCB layers to escape the perimeter pins; use 0.15 mm trace width with 0.15 mm spacing to maintain 50 ohm characteristic impedance for high-speed I/O. Place the JTAG header (TDI, TDO, TMS, TCK) on the board edge for in-system programming access without removing the device. A 10 kohm pull-up on nCONFIG and a 10 kohm pull-down on MSEL are required per the MAX II handbook for normal operation mode.
Estimated: the EPM570 I/O pins are NOT 5 V tolerant. Driving any input above VCCIO + 0.3 V causes latch-up risk. Use external level shifters (e.g., TXS0108E) when interfacing to 5 V logic. Also note that the JTAG chain shares pins with user I/O; if JTAG is unused, the four JTAG pins can be repurposed as GPIO with the appropriate Quartus assignment, but TDI must still be pulled high to VCCIO during power-up to avoid unintended JTAG activation.
Compliance Information
RoHS and REACH compliant per Altera/Intel product environmental documentation. Not AEC-Q100 qualified (commercial grade only); for automotive use consider MAX 10 or external supervisory companion. Lead-free TQFP-144 package, MSL-3 moisture sensitivity level per JEDEC J-STD-033.
