EPM240T100C4N Ringkasan

The Altera EPM240T100C4N is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs), delivering 192 macro cells with a maximum propagation delay (tPD) of 4.7 ns in a 100-pin TQFP package. Built on a low-power 0.18 µm process, it combines non-volatile Flash configuration memory with instant-on capability and in-system programmability (ISP) via JTAG, removing the need for an external boot PROM.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple glue-logic chips and larger FPGAs. In the broader programmable logic hierarchy, CPLDs are widely used for I/O expansion, bus bridging, power-up sequencing, address decoding, and interface logic glue. Compared with SRAM-based FPGAs, CPLDs do not require a configuration download at every power-up, which makes them ideal for deterministic, instant-on control logic in industrial and consumer systems.

Key features of the EPM240T100C4N include 192 macro cells organized as 240 logic elements, 4.7 ns pin-to-pin logic delay, 247.5 MHz internal performance, 80 user I/O pins, 2.5 V / 3.3 V core operation, MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, JTAG boundary-scan test (IEEE 1149.1), and a low standby current typically below 100 µA. It supports vertical migration with other MAX II density points such as the EPM570 and EPM1270 in the same 100-pin TQFP.

The MAX II architecture uses a MultiCore interconnect that routes signals across Logic Array Blocks (LABs) with predictable timing, supporting hot-socketing, open-drain outputs, and bus-hold circuitry. Designers using Quartus II software can target the device through industry-standard VHDL or Verilog HDL with the IEEE Std. 1149.1 JTAG interface.

Typical applications include I/O expansion and bus bridging, address decoding and glue logic in microprocessor/microcontroller systems, LED display driving, industrial control boards, consumer electronics interface management, and protocol translation. Engineers choose this part for instant-on, non-volatile logic that does not need a boot PROM.

Designers should confirm that all VCCIO bank voltages match the connected logic levels and ensure the JTAG chain order is correct in multi-device boards. Decoupling capacitors (0.1 µF + 1 µF) close to each VCC pin are required for clean power-up. Use the Quartus II design software for synthesis, fitting, and programming.
