LC4032C-75TN44C

Overview

The LC4032C-75TN44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 32 macrocells, 36 logic blocks, and 30 user I/Os within a 44-pin TQFP package. The device utilizes EEPROM technology for in-system programmability and supports reprogramming. Electrical specifications include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 400 MHz. It operates on a supply voltage range of 3V to 3.6V and is rated for commercial temperature conditions from 0°C to 90°C.

Feature Summary

• ispMACH 4000C architecture with 32 macrocells and 36 logic blocks
• EEPROM-based non-volatile memory enabling in-system programming
• High performance with 7.5 ns max propagation delay and 400 MHz fMAX
• 30 user I/O pins with independent output enable control

Applications

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

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the Commercial temperature grade (0°C to 90°C). Ensure compatibility with standard JTAG programming interfaces for in-system configuration. Confirm RoHS compliance status through the manufacturer's current datasheet or environmental declaration.

Selection Notes

Select this component when a moderate density CPLD with fast switching speeds is required. The 7.5 ns speed grade suits applications needing up to 400 MHz operation. Compare against the LC4032B variant if industrial temperature ranges (-40°C to 105°C) are necessary instead of commercial grades.

Part Context

This part belongs to the Lattice ispMACH 4000C family, which succeeded the ispMACH 4000A/B series. It offers enhanced performance and density compared to earlier generations while maintaining backward compatibility with existing design tools and pinouts where applicable.

Replacement Considerations

Direct functional substitutes include the LC4032V-75TN44C and LC4032ZE-75TN44C. Verify pinout compatibility and electrical characteristics before substitution.
