Overview

The Lattice Semiconductor LC4032V-75TN48C is a 3.3V In-System Programmable (ISP) CPLD from the ispMACH 4000V family. It features 32 macrocells and a 7.5 ns propagation delay, making it suitable for general-purpose logic integration. This CPLD offers 32 I/O pins with 5V tolerant capability and operates within a supply voltage range of 3V to 3.6V.

Why Choose This Part

This CPLD offers 5V tolerant I/O pins, simplifying integration with mixed-voltage systems. Its In-System Programmable (ISP) capability via an IEEE 1532 compliant interface allows for flexible design updates and field upgrades. The device also supports hot-socketing and features input pull-up/pull-down options, enhancing system robustness and design flexibility.

Applications

Glue Logic Integration
Used for combining multiple discrete logic gates and standard logic ICs into a single, compact programmable device, reducing board space and complexity.
Bus Interfacing and Bridging
Implementing custom bus interfaces, level shifting between different voltage domains (e.g., 3.3V and 5V), and creating simple bridges between incompatible buses.
Peripheral Expansion
Adding custom I/O, controlling external devices, or generating specific timing signals that are not available from a host microcontroller.
