Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the device matches the specified 160-pin PQFP package and 5-V operational requirements. Check for any manufacturing notices regarding discontinuation or specification changes prior to finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this model when a 5-V supply is required alongside high I/O density. Ensure the design accommodates the 15 ns speed grade. Verify that the 160-pin PQFP footprint aligns with the PCB layout constraints and that the 128 macrocell capacity meets the logic implementation needs.

Complex Programmable Logic Devices Part Context

This part belongs to the MACH 5 CPLD family, which offers scalable densities from 128 to 512 macrocells. The 'M5' prefix indicates 5-V operation, while '/1' denotes the recommended version for new designs. The '-15' suffix specifies the 15 ns speed grade within the commercial temperature range.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M5-128 variants with different speed grades or packages, such as M5-128/120-12YI. Cross-family migration may require architectural adjustments.
