Overview

The LC4256V-75TN100I is a high-density, low-power Complex Programmable Logic Device (CPLD) belonging to the Lattice ispMACH 4000V series. It features 256 macrocells and 64 I/O pins in a 100-TQFP package, providing a robust solution for high-speed logic integration and complex state machines with a 7.5 ns maximum propagation delay.

Why Choose This Part

This CPLD offers In-System Programmability (ISP) via a standard JTAG interface, allowing for fast design iterations and field updates. Its industrial temperature rating of -40 to 105 degrees Celsius ensures reliable operation in demanding environments while maintaining low power consumption characteristic of the ispMACH 4000V architecture.

Applications

Glue Logic Integration
Consolidating discrete logic components into a single device to reduce PCB footprint and complexity.
Bus Level Shifting
Interfacing between different I/O standards such as LVTTL, LVCMOS, and PCI across a 3.0V to 3.6V supply range.
State Machine Implementation
Executing high-speed sequential logic for system control and timing generation.
System Management
Managing power-up sequencing, reset logic, and I/O expansion in industrial and communication hardware.
