Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'SAC' against the manufacturer's current datasheet to confirm package type and temperature range. Confirm end-of-life status or obsolescence notices prior to procurement planning. Ensure design tools support the ispMACH 4A family for compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require 384 macrocells with high I/O counts (up to 192). The -12 speed grade provides 12 ns delay suitable for moderate-to-high frequency applications. Verify that the system operates within the 3.0 V to 3.6 V supply range and requires 3.3 V I/O levels compatible with 5 V inputs.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers flexible architecture with central switch matrices for 100% routability. The M4A3 series specifically denotes 3.3 V operation. The part number indicates the density (384 macrocells), I/O count (192), speed grade (-12), and package variant (SAC).

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-384 variants with different speed grades or packages. Cross-family migration to newer Lattice CPLDs may require architectural adaptation due to differences in macrocell structure and toolchains.
