Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm availability status as older series components may have limited supply or end-of-life status. Ensure design tools support the ispMACH 4A family for programming.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells with a 2:1 macrocell-to-I/O ratio. The -10 speed grade provides a 10 ns delay, suitable for moderate-speed applications. Verify that the 3.3 V operating voltage aligns with the target system power rails and that the PLCC-44 package fits the PCB footprint constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers flexible architectures for rapid logic designs. The family includes both 3.3 V (M4A3) and 5 V (M4A5) variants. The M4A3-64/32 variant specifically provides 64 macrocells with 32 dedicated I/O pins, balancing density and pin count for compact implementations.

Complex Programmable Logic Devices Replacement Considerations

Check for direct cross-model replacements within the M4A3 series, such as M4A3-64/32-10VNI or M4A3-64/32-10TCN, ensuring identical pinouts and electrical specifications before substitution.
