Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The 'V' suffix typically indicates a VQFP package, while 'C' denotes commercial temperature range. Confirm availability as lead-free options are available for this family. Check for end-of-life status if long-term supply is required.

Complex Programmable Logic Devices Selection Notes

Select the M4A3-32/32-5VC when a 3.3-V CPLD with 32 macrocells and 5.0 ns speed grade is needed. Ensure the design fits within the 32 macrocell limit and utilizes the available I/O pins. Consider the -5 speed grade for timing-critical applications requiring guaranteed fixed timing via SpeedLocking.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4A family, which offers densities from 32 to 512 macrocells. The M4A3 series specifically operates at 3.3 V, providing compatibility with modern digital systems while maintaining backward compatibility with 5-V interfaces through its bus-friendly inputs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-32 variants with different speed grades or packages. Cross-family migration may require re-evaluation of architecture differences between ispMACH 4A and newer Lattice families like MachXO or CrossLink.
