Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'NC48' against official Lattice documentation to confirm package type and lead-free status. Confirm availability as this component may be subject to end-of-life status or limited distribution channels.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 5-V operation with 32 macrocells. Ensure design constraints align with the 5.0 ns tPD specification. Consider the 48-pin TQFP footprint during PCB layout. Verify voltage levels if interfacing with 3.3-V components due to mixed-voltage safety features.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A CPLD family, which offers flexible architecture with 100% pin-out retention. The M4A5 series specifically denotes 5-V operation, distinguishing it from the M4A3 3.3-V series within the same architectural framework.

Complex Programmable Logic Devices Replacement Considerations

Check for direct replacements within the M4A5-32/32 speed grades (-5, -55, -6, etc.). Verify package compatibility if substituting with other 48-pin TQFP CPLDs.
