Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in specific datasheets. Check for end-of-life notifications or obsolescence notices from Altera/Intel prior to procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 36 I/Os are sufficient for the design. Ensure the TQFP-44 package fits the PCB layout constraints. Verify that the 3.0V–3.6V operating voltage range aligns with the system power supply. Consider MAX 7000S variants if In-System Programming (ISP) via JTAG is required.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000 family, which offers high-density programmable logic based on Altera's second-generation architecture. This series bridges the gap between simple PLDs and complex FPGAs, providing deterministic timing and easy reprogrammability.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may exist within the same MAX 7000 family with different speed grades or package options. Verify functional equivalence regarding macrocell count and I/O availability before substitution.
