EPM570GT144I5 Ringkasan

The Intel (formerly Altera) EPM570GT144I5 is a low-power MAX II Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements, 440 macro cells, and 116 user I/Os in a 144-pin TQFP (20x20 mm) package. Operating from a single 1.71 V to 1.89 V internal core supply, the device is fabricated on a 0.18 µm process and supports in-system programmability via JTAG. According to the Altera MAX II Device Handbook, the device delivers non-volatile configuration with instant-on behavior in under 200 µs, eliminating the external boot PROM required by SRAM FPGAs.

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.
