Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '5' against the required timing constraints, as it dictates the 156 MHz performance limit. Confirm the 'C' suffix corresponds to the commercial or industrial temperature range requirements for the target application environment. Ensure the TQFP-176 footprint matches the PCB design specifications.

Complex Programmable Logic Devices Selection Notes

Select this component when 512 macrocells are required for complex state machines or data path logic. The 156 MHz speed grade is suitable for moderate-speed synchronous designs. Compare against the LC4512V series if lower power consumption at reduced speeds is prioritized over the higher performance of the C-series.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000ZE family, designed for ultra-low power applications while maintaining high performance. It utilizes CMOS technology and offers non-volatile configuration storage, allowing the device to retain its program without external memory. The family supports both commercial and industrial temperature grades.

Complex Programmable Logic Devices Replacement Considerations

The LC4512C-5TN176I is an alternative variant within the same family, potentially differing in temperature rating or packaging details. Verify pin compatibility and electrical characteristics before substitution.
