Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix /1 against official documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status, as standard datasheets may not explicitly detail suffix functions. Confirm availability through authorized distributors as this component may be subject to discontinuation notices.

Complex Programmable Logic Devices Selection Notes

Select this model when a 100-pin surface-mount CPLD with 128 macrocells is required. Ensure the system voltage matches the 5V specification. Consider the 15 ns delay for timing closure. Verify that the TQFP-100 footprint aligns with the PCB design constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the MACH 5 series, designed for high-performance applications requiring large logic densities. It succeeds earlier ispMACH families by offering higher speed and density in a compact form factor. The M5 series is known for its flexible architecture and support for complex state machines.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other M5 series variants with similar macrocell counts, such as M5-256/74-15YC/1 for higher density. Cross-family migration to MachXO or ECP5 requires significant redesign due to architectural differences.
