Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm end-of-life status as distribution availability may be restricted. Ensure design tools support the ispMACH 4A family for programming and verification.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 128 macrocells and 64 I/Os with 5V compatibility. Compare the 10 ns speed grade against other grades like -5 or -7 based on timing requirements. Consider the PQFP-100 package constraints for PCB layout and thermal management.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A CPLD family, which offers densities from 32 to 512 macrocells. The M4A5 series specifically denotes 5V operation, distinct from the 3.3V M4A3 series. The family emphasizes pin-out retention and first-time-fit capabilities through its central switch matrix architecture.

Complex Programmable Logic Devices Replacement Considerations

Check for direct substitutes within the M4A5 series with different speed grades (e.g., M4A5-128/64-5YNI). Verify if newer Lattice families offer compatible pinouts and functionality if the current part is discontinued.
