Complex Programmable Logic Devices Procurement Notes

Verify package availability as the -FAI suffix indicates a specific fpBGA configuration. Confirm RoHS compliance status for lead-free requirements. Check current production status as older speed grades may be subject to discontinuation notices.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 256 macrocells with high I/O density. The -10 speed grade provides 5.5 ns delay suitable for moderate-to-high speed applications. Ensure design fits within the 167 MHz frequency constraint.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4A CPLD family offering E2CMOS technology. Provides non-volatile configuration with EEPROM storage. Supports both 3.3V and 5V JEDEC-compliant operations for system flexibility.

Complex Programmable Logic Devices Replacement Considerations

Check Lattice documentation for direct cross-references within the M4A3 series. Consider M4A3-256 variants with different speed grades (-5, -6, -7) if timing constraints allow.
