Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VI' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the component matches the original Lattice Semiconductor manufacturing specifications rather than third-party equivalents.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 5-V operation with high-speed logic performance up to 10 ns. The 128 macrocell density suits moderate complexity designs needing guaranteed fixed timing through SpeedLocking technology without excessive resource waste.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which utilizes E2CMOS technology. The family provides flexibility through various package options and supports both 3.3-V and 5-V operations, catering to diverse system integration needs while maintaining low power consumption relative to older CPLD generations.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other speed grades of the M4A5-128/64 series, such as -5 or -7 variants, provided the timing requirements are met. Verify pinout compatibility when substituting different speed grades.
