Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required voltage and speed grade specifications. Ensure compliance with RoHS directives if applicable to the manufacturing batch. Check for any discontinuation notices as older CPLD families may have limited availability.

Complex Programmable Logic Devices Selection Notes

Select this model when a 3.3-V supply is required alongside 128 macrocells and approximately 74 I/Os. The 7.5 ns speed grade is suitable for applications requiring moderate timing margins. Consider pinout retention benefits if migrating designs from lower-density devices within the same package footprint.

Complex Programmable Logic Devices Part Context

This component belongs to the MACH 5 family, which offers high-density logic integration using fifth-generation architecture. The M5LV designation specifically indicates 3.3-V operation, distinguishing it from the 5-V M5 series. The family provides flexible routing and multiple density options to support various system logic requirements.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the MACH 5 family include other 128-macrocell variants such as M5LV-128/68-7VC or M5LV-128/120-7VC, depending on I/O count needs. Verify package compatibility and ensure that the replacement part maintains the required 3.3-V operating voltage and 7.5 ns speed grade.
