EPM570GT144I5 Overview
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that bridges the gap between discrete glue logic (74-series gates) and high-density FPGAs. CPLDs use a classic AND-OR (PLA-style) architecture with non-volatile flash configuration memory, giving them instant-on behavior and deterministic timing. In the broader taxonomy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. MAX II CPLDs are positioned as low-power, low-cost glue-logic replacements for ASICs, microcontrollers, and small FPGAs.
Key features include a maximum pin-to-pin propagation delay (tPD) of 5.4 ns at industrial temperature, an internal oscillator, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels, and 8 Kbits of user flash memory. The 144-TQFP package provides a thermal resistance of approximately 26 C/W (theta_JA) and supports commercial (0 °C to +85 °C) operation with the I5 industrial-grade speed/temperature suffix.
The MAX II architecture uses a uniform Logic Element Array (LEA) of 570 Logic Elements, each containing a 4-input look-up table and a programmable flip-flop, fed by a global interconnect. The flash-based configuration is single-chip (no boot device) and supports live updates via JTAG or the built-in Altera programming interface. This makes the EPM570GT144I5 well-suited to applications requiring instant-on, deterministic timing, and small logic capacity with low standby power.
Typical applications include I/O expansion and bus bridging in industrial controllers, LED display drivers, glue-logic replacement for legacy 74HC designs, power-sequencer controllers, and configuration watchdog logic. The 116 user I/Os are sufficient for mid-density parallel interfaces such as 16-bit data + control buses, LCD/LED matrix driving, and address decoding. The device is well suited to designs where instant-on behavior and low quiescent current are more important than raw logic density.
When designing with the EPM570GT144I5, pay attention to supply decoupling (four 0.1 µF capacitors placed close to each VCCIO/GND pair is the recommended pattern from the MAX II handbook) and to JTAG signal integrity on long board traces. The internal core must be supplied separately from the I/O banks, but all rails can be derived from a single 3.3 V source through onboard regulation.

Typical Applications
EPM570GT144I5 is suitable for 7 applications: Industrial I/O Expansion and Bus Bridging, Power-Sequencer and Reset Controller, LED Display and Matrix Driving, Glue Logic Replacement, Configuration Watchdog for FPGAs, Motor Control Timing and PWM, Test and Measurement Front-End Logic.
Industrial I/O Expansion and Bus Bridging
The EPM570GT144I5 is well suited to industrial I/O expansion and bus bridging between microcontrollers, FPGAs, and peripheral ICs. Its 116 user I/Os and 5.4 ns pin-to-pin delay support fast address decoding for external memory and parallel buses such as 16-bit data plus control signals. The instant-on flash configuration ensures deterministic startup before the main MCU or FPGA is ready, which is critical in factory-automation controllers and PLC I/O modules. MultiVolt I/O banks allow direct interfacing with 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic on the same device.
Recommended
Power-Sequencer and Reset Controller
The EPM570GT144I5 is an excellent fit for power-sequencer and reset-controller ICs in multi-rail systems. The non-volatile flash configuration wakes the device in under 200 µs, allowing it to drive enable signals to DC-DC converters and LDO regulators before the main processor boots. The 570 LEs and 440 macro cells are sufficient for sequencing 6-12 rails with adjustable delays and watchdog logic. The deterministic 5.4 ns timing guarantees that reset pulses meet downstream processor timing requirements without metastability risk.
Recommended
LED Display and Matrix Driving
The EPM570GT144I5 serves as a row/column driver controller in LED display and matrix driving applications. The 116 user I/Os allow direct multiplexing of 8-row by 16-column monochrome panels or 8-row by 8-column RGB panels without external drivers. The MAX II architecture supports PWM generation in firmware, enabling per-LED brightness control at refresh rates above 1 kHz. The industrial temperature range allows operation in outdoor signage and transportation displays, while the in-system programmability simplifies firmware updates in the field.
Recommended
Glue Logic Replacement
The EPM570GT144I5 directly replaces legacy 74HC and 74LVC discrete glue-logic ICs, integrating dozens of AND, OR, NAND, flip-flop, multiplexer, and counter functions into a single package. The 570 LEs typically absorb 15-25 standard 74-series devices, reducing PCB area, BOM cost, and supply-chain complexity. The 144-TQFP package provides enough I/O to handle wide bus decoding and registered buffering, while the flash-based non-volatile configuration eliminates manual jumper setting or socket changes during prototype iterations.
Recommended
Configuration Watchdog for FPGAs
The EPM570GT144I5 is commonly used as a configuration watchdog for larger FPGAs such as Intel Cyclone or Stratix series. The MAX II CPLD boots before the main FPGA is configured, monitors the FPGA's CONFIG_DONE and nSTATUS pins, and triggers a reconfiguration cycle if the FPGA fails to complete startup within a defined window. The 8 Kbits of user flash can store a golden backup bitstream that the CPLD streams to the FPGA on watchdog timeout, providing a robust fault-recovery path in telecommunications and aerospace applications.
Recommended
Motor Control Timing and PWM
The EPM570GT144I5 generates deterministic PWM signals for stepper motor and BLDC motor control applications. With 116 user I/Os, the device can drive up to 8 half-bridges with complementary outputs, hardware dead-time insertion, and fault input handling. The 5.4 ns pin-to-pin delay ensures that commutation events are accurately timed relative to rotor position sensors, reducing torque ripple. The industrial temperature range and 1.8 V core supply suit robotics, CNC machinery, and small electric vehicle controllers where reliability is critical.
Recommended
Test and Measurement Front-End Logic
The EPM570GT144I5 is used in test and measurement instruments as front-end logic for signal routing, channel selection, and trigger conditioning. The 116 user I/Os handle multi-channel analog multiplexer control, range switching relays, and trigger gating at frequencies above 100 MHz when internal counters are cascaded. The instant-on behavior allows the test equipment to enter a known safe state immediately at power-up, protecting sensitive DUTs. The non-volatile configuration stores factory calibration state across power cycles without battery backup.

Design Notes
The EPM570GT144I5 requires a separate 1.8 V core rail (VCCINT, 1.71-1.89 V) derived from the system 3.3 V via a low-noise LDO such as the TI TPS7A4533 or equivalent. Each of the four VCCIO banks can be independently supplied at 1.5 V, 1.8 V, 2.5 V, or 3.3 V to support mixed-voltage interfacing. Decoupling: place one 0.1 µF X7R ceramic capacitor within 2 mm of each VCCINT and VCCIO pin, plus a single 10 µF bulk capacitor near the package. Inadequate decoupling causes VCCIO noise that can couple into JTAG signals and produce programming failures.
Estimated: at 30 mA quiescent current and 1.8 V core, the EPM570GT144I5 dissipates approximately 54 mW. The 144-TQFP package has a theta_JA of approximately 26 C/W (with standard JEDEC test board copper), giving a temperature rise of just 1.4 C above ambient - well below the 100 C industrial limit. The exposed-pad variant is not available for the 144-TQFP; rely on internal bond-wire and lead-frame paths. PCB layout should connect all GND pins to a continuous ground plane with at least four vias per GND cluster.
Do not leave JTAG pins (TDI, TMS, TCK, TDO) floating in production - tie TDI and TMS to VCCIO1 through 10 kohm pull-ups and TCK to GND through a 10 kohm pull-down to prevent spurious JTAG state transitions in noisy environments. The nCONFIG pin must be held high in user mode; if pulled low, the device erases and reconfigures, which can cause glitches on the I/O pins. The DEV_OE pin must also be tied high in user mode to enable user I/O outputs; leaving it floating risks high-Z states during power-up.
Long JTAG chains can suffer from signal integrity issues if the TCK frequency exceeds 16 MHz. Keep JTAG trace lengths under 75 mm and avoid routing them parallel to high-frequency switching signals. For multi-device JTAG chains, add a 33 ohm series-termination resistor near the TCK driver to dampen reflections. The Altera MAX II Device Handbook recommends keeping the JTAG signal reference plane (ground) continuous under the JTAG traces, with no splits or voids, to control impedance.
