LC4032C-25TN44C

Overview

The LC4032C-25TN44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/B/C/Z family. It features 32 macrocells, 36 logic blocks, and 30 user I/O pins within a 44-pin TQFP package. The device utilizes EEPROM technology for in-system programmability and supports reprogramming. Electrical specifications include a maximum operating frequency of 400 MHz, a propagation delay of 7.5 ns, and an operating voltage range of 3.0 V to 3.6 V. It operates within a commercial temperature range of 0 °C to 90 °C.

Feature Summary

• ispMACH 4000V architecture with 32 macrocells and 36 logic blocks
• EEPROM-based non-volatile configuration supporting in-system programming
• High performance with 7.5 ns propagation delay and 400 MHz max frequency
• 30 user I/Os with independent output enable control

Applications

• General-purpose digital logic implementation
• Bus protocol bridging and translation
• Address decoding and control logic
• State machine implementation

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the commercial temperature grade variant within the 4000V family. Ensure compatibility with standard JTAG programming interfaces and confirm RoHS compliance status for the specific manufacturing batch prior to integration.

Selection Notes

Select this component when a moderate density CPLD with high-speed performance is required. The 32-macrocell count suits designs needing up to 30 I/O lines. Compare against the LC4032B or LC4032Z variants if different feature sets or industrial temperature ranges are needed instead of the commercial grade specified here.

Part Context

This part belongs to the Lattice ispMACH 4000V/B/C/Z family, which offers high-density PLDs with SuperFAST technology. The family provides flexibility through multiple voltage options (3.3V/2.5V/1.8V) and various package types, positioning it as a solution for replacing discrete logic in space-constrained applications.

Replacement Considerations

Direct pin-compatible replacements within the same family include LC4032V-25TN44C and LC4032B-25TN44C. Verify that the alternative suffix matches the required temperature range and electrical characteristics before substitution.
