Complex Programmable Logic Devices Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability should focus on authorized distributors or secondary market suppliers, as standard procurement channels may not stock new units. Confirm the specific suffix 'FAI' matches the required package and temperature grade, as ordering suffixes define physical attributes.

Complex Programmable Logic Devices Selection Notes

Select this part when a design requires 384 macrocells with high I/O count in a surface-mount BGA footprint. The -14 speed grade indicates a 14 ns maximum propagation delay. Ensure the system design accommodates the 3.3-V core voltage and verify that the 256-pin fpBGA package fits the board layout constraints compared to larger BGA options.

Complex Programmable Logic Devices Part Context

The M4A3-384/192-14FAI belongs to the ispMACH 4A CPLD family, which offers flexible architecture with central switch matrices for 100% routability. This specific model represents one of the higher density options in the 3.3-V series, providing significant logic capacity while maintaining compatibility with legacy 5-V interfaces through its input tolerance capabilities.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the device is discontinued, engineers should evaluate newer Lattice families such as MachXO3 or CrossLink-NX for equivalent logic density and I/O counts, ensuring pinout compatibility or redesigning the PCB if necessary.
