Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm package type TQFP-48 matches design requirements. Check RoHS compliance status as per latest manufacturer documentation. Ensure ESD handling procedures are followed during procurement and storage.

Selection Notes

Select this model when non-volatile CPLD functionality is required with moderate logic density. Compare against LC4032V series if lower power consumption is critical, noting potential speed differences. Verify pin compatibility with existing TQFP-48 footprints. Consider thermal management for industrial environments.

Part Context

Part of the ispMACH 4000C family, succeeding earlier ispMACH 4000 designs. Offers improved performance over legacy CPLDs while maintaining low power characteristics. Commonly used in cost-sensitive applications requiring reliable, non-volatile logic control without FPGA complexity.

Replacement Considerations

Direct pin-compatible replacements may include LC4032V-5T48I or LC4032ZE-5TN48C. Verify electrical specifications and temperature grades match application requirements before substitution.
