LC4256V-75TN176I
Overview
The LC4256V-75TN176I is a high-density Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispMACH 4000V series. It features 256 macrocells and 128 I/O pins in a 176-TQFP package, offering 7.5 ns propagation delay for high-speed logic integration. This device operates at 3.3V and is designed for industrial applications requiring 5V-tolerant inputs and low static power consumption.
Why Choose This Part
This CPLD combines high-speed performance with a low typical standby current of 128uA, making it suitable for power-sensitive designs. Its 5.5V tolerant inputs allow for easy interfacing in mixed-voltage environments without external level shifters. The In-System Programmable nature via JTAG ensures fast prototyping and simplified field updates.
Applications
Key Specifications
Getting Started
Design entry is typically performed using Lattice Diamond or ispLEVER Classic software, supporting VHDL and Verilog synthesis. Hardware programming is achieved via a standard JTAG interface using a Lattice USB programming cable. For evaluation, look for ispMACH 4000V family development kits or reference designs that target the 176-pin TQFP footprint.
