Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'JI' against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as specifications may vary by production batch. Check for end-of-life notifications or obsolescence warnings prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 5V operation with 64 macrocells. Ensure the design fits within the 32 I/O limit. Consider the -10 speed grade if a 10 ns maximum propagation delay is required. Verify that the TQFP-44 package dimensions match the PCB footprint requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A CPLD family, which provides high-density programmable logic solutions. The M4A5 series specifically denotes 5V operation, distinguishing it from the 3.3V M4A3 series. The family emphasizes first-time-fit capabilities and pin-out retention across design revisions.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other speed grades of the M4A5-64/32 series, such as M4A5-64/32-10VC or M4A5-64/32-7JI, provided the electrical parameters meet the design constraints. Cross-family replacements require careful verification of I/O counts and voltage levels.
