• Automotive electronics within specified temperature limits.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +105°C). Confirm the package type is TQFP-100. Ensure the design accounts for the 1.8V supply requirement. Check for RoHS compliance status as indicated in official datasheets.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the logic density requirements. Choose the TN100 package for surface-mount applications needing 100 pins. Consider the 2.5 ns delay for timing-critical paths. Compare against LC4064V or LC4064ZE variants if different voltage levels or performance characteristics are needed.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V/B/C/Z family of CPLDs. It shares architectural similarities with other members like LC4064C-10TN100I but differs in speed grade and temperature rating. The family is known for combining high performance with low power consumption using EEPROM technology.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades within the LC4064C series, such as LC4064C-10TN100I, provided timing constraints allow for slower speeds. Cross-family migration to LC4064V or LC4064ZE requires verification of voltage compatibility and pinout alignment.
