Overview

The LC4128V-75TN144C is a high-performance ispMACH 4000V series Complex Programmable Logic Device (CPLD) featuring 128 macrocells and a fast 7.5ns propagation delay. Operating at a 3.3V supply, it provides a balance of low power consumption and high-speed logic execution for time-critical digital systems.

Why Choose This Part

This CPLD offers excellent First-Time-Fit and refit capabilities through its SpeedLocking Path architecture, ensuring timing consistency during design iterations. It features hot-socketing support and 5V-tolerant I/O, making it robust for mixed-voltage environments and backplane applications.

Applications

I/O Expansion
Adding 5V-tolerant digital I/O to low-voltage microcontrollers or processors using the device's 144-pin TQFP package.
State Machine Implementation
Executing complex control logic and fast counters that require deterministic timing and wide input gating.
Bus Level Shifting
Interfacing between 3.3V, 2.5V, and 1.8V logic levels with 5V tolerance for legacy peripheral support.
Glue Logic
Consolidating multiple discrete logic gates, address decoders, and reset circuitry into a single programmable chip.

Getting Started

Development is typically performed using Lattice Diamond or ispLEVER Classic software. The device supports In-System Programming (ISP) via a standard IEEE 1532 JTAG interface, allowing for firmware updates directly on the PCB.
