Overview

The EPM240T100I5N is a Complex Programmable Logic Device (CPLD) based on Altera's MAX II architecture, utilizing a non-volatile lookup-table-based architecture. It provides 192 macrocells and 240 logic elements in a 100-pin TQFP package, offering a low-power solution for system integration tasks. This device is designed for industrial temperature ranges, operating between -40C and 100C.

Why Choose This Part

The MAX II architecture combines the non-volatile memory of a CPLD with the high-density logic typical of low-end FPGAs. It features a fast propagation delay of 4.7 ns and includes integrated features like Schmitt trigger inputs, open-drain outputs, and weak pull-up resistors to reduce external component count.

Applications

I/O Expansion
Adding extra GPIO, level shifting, or drive strength to microcontrollers with limited pins.
Interface Bridging
Converting between different serial or parallel protocols such as SPI, I2C, or custom bus logic.
Power-Up Sequencing
Managing complex multi-rail power sequencing and system reset logic on high-end processor boards.
Glueless Interface Logic
Connecting memory chips or peripherals to a processor without requiring discrete logic gates.
