Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'F256' corresponds to the 256-pin FineLine BGA package dimensions and pinout. Confirm the temperature grade 'C' indicates commercial operation range. Ensure the 'B' variant designation aligns with the required electrical characteristics and revision level for your design integration.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require more than 256 macrocells but less than 512, balancing density with power efficiency. The multi-voltage capability allows direct interfacing with legacy 5 V systems while utilizing lower voltage cores for reduced dynamic power. Consider the 256-pin package availability if board space permits larger footprints compared to smaller PLD options.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V series, which succeeded the ispLSI 2000 and ispMACH 4000 families. It combines high density with low power consumption, targeting applications that need reliable, non-volatile configuration without the complexity of FPGA flow tools. It serves as a drop-in replacement for older GALs and CPLDs in established hardware architectures.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other 384-macrocell devices within the ispMACH 4000 family, such as the LC4384Z or LC4384B variants with compatible packages. Verify pin-to-pin compatibility when substituting with newer revisions or alternative manufacturers offering similar CPLD architectures.
