EPM570T144I5N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with on-chip EEPROM or flash configuration memory, providing instant-on behavior at power-up with no external boot PROM. Within the broader taxonomy, the EPM570T144I5N sits at: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. MAX II devices use 0.18 um CMOS process technology with internal 3.3 V core supply and 1.5 V/1.8 V/2.5 V/3.3 V user-selectable I/O bank supplies (VCCIO), enabling mixed-voltage interfacing to legacy 5 V-tolerant buses through level shifters.
Key features include MultiVolt I/O support, in-system programmability (ISP) via JTAG (IEEE 1149.1), IEEE 1149.1 boundary-scan test, 4-input look-up tables, expansion via the chainable Lab/CLR chain, and 100% non-volatile configuration storage. Per the MAX II Family datasheet, the EPM570T144I5N targets power-sensitive glue-logic tasks such as bus decoding, interface bridging, and power-up sequencing. RealMAX II devices also integrate a user flash memory block that engineers use for serial number storage or trim calibration.
Typical applications include I/O expansion and decoding for microcontrollers without sufficient native I/O, bus interface bridging between 3.3 V and 1.8 V logic families, LED display row/column drivers, power-supply sequencing controllers, and FPGA/CPLD configuration supervision. The non-volatile, instant-on architecture eliminates external configuration memory and reduces BOM cost versus SRAM-based FPGAs in fixed-function designs.
A key design consideration is thermal and I/O budgeting - although the TQFP-144 package exposes all four sides for trace fan-out, the industrial -40C to +100C ambient range (TJ +100C max for I5N speed grade) requires derating for systems housed in enclosed enclosures without airflow. When designing, leave at least two ground pins on every TQFP side as return paths and connect all VCCINT/VCCIO pairs.

Typical Applications
EPM570T144I5N is suitable for 6 applications: Microcontroller I/O Expansion and Bus Decoding, Mixed-Voltage Logic Family Bridging, Power Supply Sequencing Controller, LED Display Row/Column Driver, FPGA Configuration Supervisor / Watchdog, Industrial Control Glue Logic (EOL Migration).
Microcontroller I/O Expansion and Bus Decoding
The EPM570T144I5N adds 116 user I/O pins and 570 logic elements to an MCU that has insufficient native GPIO, offloading bus decoding, chip-select generation, and address-latch duties from software to hardware. With 8.7 ns tPD and 304 MHz internal performance per the MAX II datasheet, it generates glue-logic signals faster than any Cortex-M firmware loop, freeing the MCU for application code. Typical insertion: place the EPM570 between the MCU FSMC bus and peripheral devices (SRAM, NAND flash, LCD), with 3.3 V VCCINT and mixed 1.8 V/3.3 V VCCIO banks to bridge to peripherals.
Recommended
Mixed-Voltage Logic Family Bridging
The EPM570T144I5N's four MultiVolt I/O banks each accept independent VCCIO levels of 1.5 V, 1.8 V, 2.5 V, or 3.3 V per the MAX II datasheet, making it ideal for translating signals between an old 3.3 V microcontroller and a new 1.8 V FPGA or DDR memory. With 440 macrocells it can buffer 32+ data lines plus full handshaking without external translators, saving PCB area and BOM cost. Insertion: VCCINT to 3.3 V, bank 1 to 3.3 V for MCU side, bank 2 to 1.8 V for FPGA side; tie unused banks to GND or VCCIO per datasheet recommendation.
Recommended
Power Supply Sequencing Controller
The EPM570T144I5N's non-volatile, instant-on behavior makes it a reliable sequencing controller for multi-rail systems where the rails must power up in a defined order - the CPLD configures at 100 us from internal flash per the MAX II datasheet, then drives PG (power-good) signal cascades to enable buck regulators in sequence. With 8 Kbits of user flash memory it stores calibration constants for the sequencing timing. Insertion: each regulator's PG pin feeds a TQFP-144 I/O pin; logic outputs drive the next regulator's EN pin, generating a daisy-chain startup sequence without software control.
Recommended
LED Display Row/Column Driver
The EPM570T144I5N drives large LED matrix displays by time-multiplexing rows and latching column data - 116 user I/O pins and 304 MHz internal performance allow it to refresh 16-row x 32-column displays with >1000 Hz row rates, eliminating flicker per the MAX II datasheet timing specifications. With 8 Kbits UFM it stores font tables and animation patterns, offloading character ROM from the host MCU. Insertion: 16 outputs to row-driver MOSFET gates, 32 outputs to column-source shift registers; operate at 3.3 V VCCINT with 5 V-tolerant shift registers via external buffers.
Recommended
FPGA Configuration Supervisor / Watchdog
The EPM570T144I5N acts as a co-processor that monitors an FPGA's CONFIG_DONE and nSTATUS pins, asserts nCONFIG for reconfiguration if a watchdog timeout expires, and bridges JTAG between the FPGA and an external programmer - per the MAX II datasheet, the EPM570's 8.7 ns tPD and JTAG capability make it a single-chip supervisor with sub-microsecond fault response. The non-volatile instant-on behavior ensures the supervisor is operational before the FPGA finishes its configuration, eliminating a common multi-supply race condition.
Recommended
Industrial Control Glue Logic (EOL Migration)
For industrial PLC and motor-control boards originally designed around the EPM570T144I5N, the part's Last Time Buy status forces a migration decision. The EPM570GT144I5N is a pin-compatible drop-in replacement on the same TQFP-144 land pattern per Intel's MAX II G family datasheet, allowing field-installed baseboards to be re-qualified without PCB rework. With industrial -40C to +100C operating range and non-volatile configuration, it survives the same factory-floor vibration and temperature stress as the original.

Key Differentiators
- Drop-in compatible with the MAX II G variant on the same TQFP-144 footprint (vs EPM570GT100I5N)
- Wider operating temperature for automotive applications (vs EPM570T144I5N (vs EPM570T144A5N))
- Smaller and cheaper than EPM1270 while keeping the same TQFP-144 footprint (vs EPM1270T144I5N)
Design Notes
Per the MAX II datasheet, the TQFP-144 package requires careful power-pin decoupling. Place one 0.1 uF X7R ceramic capacitor within 100 mils (2.5 mm) of every VCCINT/VCCIO pin pair, and add a single 10 uF bulk tantalum or ceramic capacitor near the package. Connect all GND pins to a continuous ground plane on the top or second layer - split grounds or ground traces (instead of planes) cause EMI and signal-integrity problems above 50 MHz internal frequencies. Estimated: total decoupling count for TQFP-144 is roughly 12 VCC pairs requiring 12 x 0.1 uF + 1 x 10 uF minimum.
Route JTAG signals (TDI, TDO, TMS, TCK, optional TRST) as a daisy chain to the EPM570T144I5N with a 4.7 kohm pull-up on TCK and TMS per the MAX II datasheet. Keep JTAG traces under 6 inches (150 mm) and avoid routing near high-speed switching edges - the JTAG state machine can be corrupted by capacitive coupling. When using a 10-pin Altera USB-Blaster header, place the connector within 2 inches of the JTAG pins. If the board is in a noisy industrial environment, add a 100 ohm series resistor on TCK near the CPLD for additional EMI immunity.
Do not leave unused I/O pins floating - per the MAX II datasheet, configure them as outputs driving ground or as inputs with internal weak pull-up enabled in the Quartus II pin-assignment file. Floating inputs can oscillate, draw excessive ICC, and cause unreliable behavior. Also ensure VCCIO is supplied to all four I/O banks, even if a bank is unused, with the bank voltage matching the I/O standard you assign; unpowered VCCIO pins cause input-buffer latch-up. Finally, do not assume that any 'EPM570' designation guarantees industrial temperature range - the 'C5' speed grade is commercial (0C to +85C), not industrial.
The TQFP-144 package has a theta_JA of approximately 28 C/W (per typical MAX II thermal data) when mounted on a 4-layer JEDEC test board with continuous ground/power planes. Estimated: at 100C industrial max ambient and 1.0 W total power dissipation (typical for a logic-only 570-LE design at 100 MHz toggling), the junction temperature rise is roughly 28 C, giving TJ of about 128 C - within the 135 C maximum for industrial-grade plastic. For sealed enclosures without airflow, derate clock frequency or add thermal vias under the exposed pad footprint area to keep TJ below 110 C.
Compliance Information
Per Altera/Intel product page and DigiKey listing, the EPM570T144I5N is RoHS compliant with lead-free (e1) matte-tin termination. Industrial temperature grade only - for AEC-Q100 automotive qualification, choose the A5N variant. Halogen-free status not explicitly stated in the verified web data.
