Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'JNI' against official Lattice documentation to confirm package type and temperature grade. Confirm end-of-life status or availability through authorized distributors as this part number may be discontinued. Ensure design tools support the ispMACH 4A family for compilation.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells and 32 I/Os in a 100-pin package. Compare the 12 ns speed grade against other variants like the -10 or -7 if higher performance is needed. Consider the M4A3-64/64 variant if 64 I/Os are required instead of 32. Verify power consumption requirements against the static current specifications for the 3.3 V family.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers densities from 32 to 512 macrocells. The family provides both 3.3 V and 5 V operation options. The M4A3 series specifically targets 3.3 V applications while maintaining compatibility with 5 V inputs for mixed-voltage systems.
