• General-purpose programmable logic applications

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VC' against the manufacturer's current documentation to confirm package type and temperature range. Confirm RoHS status as datasheets may vary by revision. Check for lead-free package availability if required by project specifications.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells and 64 I/Os at 5 V operation. Ensure the 5.5 ns propagation delay meets timing requirements. Consider the M4A3-128 variant if 3.3 V operation is preferred. Verify pin-out retention needs against the TQFP package options available for this density.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A CPLD family, which offers densities from 32 to 512 macrocells. The family provides flexible architectures with central switch matrices for high routability. It supports both 3.3 V and 5 V operations across various packages including TQFP, PQFP, PLCC, and BGA types.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other speed grades of the M4A5-128 series, such as -5, -55, -6, -65, -10, or -12 variants, provided timing constraints are met. Cross-family migration to ispMACH 4000V/Z requires architectural re-evaluation.
