Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix corresponds to the required package and temperature grade, as variations exist within the family. Ensure compliance with relevant environmental regulations such as RoHS before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 96 macrocells are sufficient for the design complexity. The 12 ns speed grade offers a balance between performance and resource utilization. Consider the 1:1 macrocell-to-I/O ratio architecture which simplifies routing compared to 2:1 variants. Verify voltage compatibility if interfacing with 3.3V logic, as this is a 5V device.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A series, designed for high-performance E2CMOS applications. It provides flexible architecture with central switch matrices for 100% routability. The family supports both 3.3V and 5V operations, offering pin-out retention across design iterations.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density include other speed grades of the M4A5-96/48 series, such as M4A5-96/48-10VI or M4A5-96/48-7VNI. Cross-family migration to M4LV or M4A3 may require voltage level adjustments and architectural re-evaluation.
