Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm package integrity for the TQFP-44 form factor. Ensure programming tools support the ispMACH 4000C architecture for successful configuration.

Selection Notes

Select this model when non-volatile storage is required to retain design data without external memory. Compare against the LC4032V series if lower power consumption is critical, as the V-series may offer different electrical characteristics. Verify pin compatibility if replacing older GAL devices.

Part Context

This part belongs to the ispMACH 4000C family, which bridges the gap between simple PLDs and complex FPGAs. It offers high density for its class with fast throughput and low power consumption, making it suitable for cost-sensitive embedded systems requiring flexible logic.

Replacement Considerations

Direct pin-compatible replacements include other members of the ispMACH 4000C family such as the LC4032C-75TN44C, provided the temperature grade matches requirements.
