Overview

The EPM570T100I5N is a non-volatile CPLD from the Altera MAX II family, featuring 570 logic elements and 440 macrocells in a 100-pin TQFP package. It utilizes an instant-on architecture with an internal MultiVolt core, providing a cost-effective alternative to high-density FPGAs for low-power control and interface applications.

Why Choose This Part

The device offers a very fast propagation delay (tpd) of 5.4 ns and includes a dedicated User Flash Memory (UFM) block for storing non-volatile data. Its MultiVolt core supports operation from 2.5V or 3.3V supplies while remaining 5V-tolerant, simplifying power management in mixed-voltage environments.

Applications

I/O Expansion
Increasing the number of available general-purpose I/O pins for a host processor with 76 available GPIOs and 5V tolerance.
System Power Sequencing
Managing complex power-up and power-down sequences for multi-rail board designs using its non-volatile, instant-on capability.
Interface Bridging
Translating between different logic levels and protocols, such as interfacing 3.3V legacy peripherals with lower voltage modern processors.
Bus Management
Implementing bus-hold circuitry and programmable pull-up resistors for managing shared data buses in complex digital systems.
