Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '5VC48' against the manufacturer's current product selector guide to confirm package type (TQFP), speed grade (-5), and temperature range (Commercial). Ensure compatibility with existing design tools for the ispMACH 4A family.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 32 macrocells with a 1:1 macrocell-to-I/O ratio. The -5 speed grade provides 5.0 ns delay suitable for high-frequency applications. Consider the 44-pin TQFP form factor for board space constraints compared to BGA options.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4A family, which bridges the gap between standard PLDs and larger CPLDs. The family emphasizes first-time-fit success and predictable timing through its unique switch matrix architecture and SpeedLocking feature.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density and package are limited due to the specific 1:1 macrocell/I/O configuration of the M4A3-32/32 variant. Verify pinout compatibility if considering other 32-macrocell devices from different families.
