Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'BI' corresponds to the required industrial temperature grade and RoHS compliance status, as packaging and environmental ratings can vary by manufacturing lot. Check for end-of-life notifications or obsolescence notices prior to procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design complexity. Ensure the 256-pin FTBGA/FGA package fits the PCB footprint constraints. Verify that the 1.8V core voltage aligns with the system's power rails. Compare against the LC4256C series if higher performance or updated features are required.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000ZE CPLD family, designed for low-power, high-performance applications. It utilizes non-volatile Flash technology, allowing for instant-on functionality without external configuration memory. The family is known for supporting both parallel and serial programming modes.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other members of the LC4256B family with different speed grades (e.g., LC4256B-7). Cross-family migration to LC4256C requires verification of timing and feature compatibility.
