Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'FANC' against the manufacturer's current datasheet to confirm package type, temperature range, and lead-free status. Confirm availability as this component may be subject to discontinuation notices or limited supply conditions.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring high I/O counts (up to 192) within a single CPLD. Ensure the application benefits from the 6.5 ns propagation delay and 154 MHz operating speed. Verify that the 256-ball BGA package fits the board space constraints and that the design tool supports the ispMACH 4A architecture.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which offers flexible PAL blocks interconnected by a central switch matrix. The M4A3-384 variant provides one of the highest densities in the 3.3-V series, suitable for replacing multiple lower-density devices in complex logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-384 speed grades (e.g., -10, -7). Cross-family migration to newer Lattice CPLDs requires verification of pin compatibility and software tool support.
