Part Context

This component belongs to the ispMACH 4000V/B/C/Z family of superfast high-density PLDs. The 'B' suffix denotes the specific generation within this series, offering improved performance over previous iterations while maintaining compatibility with standard CPLD design flows.

Replacement Considerations

Compatible replacements include other members of the ispMACH 4000 family such as the LC4032V or LC4032Z variants, provided they match the required pin count and speed grade. Verify that the substitute part supports the necessary I/O voltage levels.
