Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm availability status as older series components may have limited supply or end-of-life implications. Ensure design tools support the ispMACH 4A family for successful implementation.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require high I/O counts within a single CPLD without sacrificing timing predictability. The -10 speed grade is suitable for commercial environments where 125 MHz performance is sufficient. Consider the fpBGA package constraints if space is limited, ensuring the board layout accommodates the specific ball grid array dimensions.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4A family, which bridges the gap between simple PLDs and complex FPGAs. The family is characterized by its E2CMOS process, allowing for non-volatile configuration and low static power consumption compared to SRAM-based devices. It serves as a drop-in replacement for many PAL/GAL legacy designs while offering significantly higher density.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-256 variants with different speed grades or I/O configurations, such as the M4A3-256/192-7FANC. Verify that any substitute maintains the required 10 ns propagation delay and matches the physical footprint if PCB re-spin is not an option.
