Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T100C' against official Lattice documentation to confirm pinout compatibility and electrical characteristics, as distributor listings may vary. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Ensure the source document explicitly identifies this part number as active or obsolete to avoid procurement of end-of-life components.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with fast switching speeds is required. Compare against the XC95108 for legacy compatibility or higher gate counts if necessary. Consider the LC4128Z series if lower voltage operation is needed. Verify that the 100-pin TQFP package fits the available PCB footprint and thermal constraints.

Complex Programmable Logic Devices Part Context

This device belongs to the ispMACH 4000V family, designed for high-performance, low-power applications. It serves as a successor to older GAL and PAL devices, offering non-volatile configuration and high I/O flexibility. The family is widely used in mixed-signal systems where deterministic timing and reprogrammability are critical.

Complex Programmable Logic Devices Replacement Considerations

The AMD XC95108-15PC84C is listed as a similar alternative, though it differs in package type and speed grade. Direct pin-to-pin replacements may not exist; functional equivalence requires careful review of I/O counts and voltage levels. Consult Lattice's official cross-reference guides for verified substitutes.
