Overview
The LC4128V-75TN144I is a high-performance Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 128 macrocells and 96 I/O pins in a 144-TQFP package, designed for high-speed logic integration with a fast 7.5 ns propagation delay. This device operates on a 3.3V internal supply and includes 5V tolerant inputs to facilitate easy communication across mixed-voltage systems.
Why Choose This Part
The device offers a robust industrial temperature range of -40 to 105 degrees Celsius, making it suitable for harsh environments. Its In-System Programmability (ISP) via JTAG allows for easy field updates and rapid prototyping, while the high I/O count of 96 pins provides significant flexibility for dense interconnect designs.
Applications
Key Specifications
Getting Started
Development is typically performed using Lattice Diamond or ispLEVER Classic software, which supports VHDL and Verilog entry. Programming is achieved through the integrated JTAG interface using a Lattice HW-USBN-2B programming cable or compatible ISP hardware. Engineers should consult the ispMACH 4000V family data sheet for specific pin-out and power decoupling requirements.
