Complex Programmable Logic Devices Procurement Notes

Verify the specific package type associated with the YNC suffix against official Lattice documentation to ensure physical compatibility. Confirm that the -10 speed grade meets the timing requirements of the target design. Check for lead-free status if environmental compliance is required.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are required with exactly 160 available I/O pins. The -10 speed grade provides a 7.5 ns delay suitable for moderate-speed applications. Ensure the design fits within the 1:1 macrocell-to-I/O ratio architecture defined for this density.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers high-performance E2CMOS programmable logic. The family provides flexibility through SpeedLocking technology and 100% pin-out retention across design revisions. It bridges the gap between simple PLDs and complex FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Check for direct cross-references within the M4A3 series. Verify if higher density variants like the M4A3-256/192 or lower density M4A3-256/128 meet functional needs while maintaining pin compatibility.
