Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the commercial temperature grade (0°C to 90°C junction). Confirm package integrity for the 176-pin TQFP form factor. Check current availability status as older CPLD families may have limited production runs or obsolescence notices from Lattice Semiconductor.

Complex Programmable Logic Devices Selection Notes

Select this component when 384 macrocells are sufficient for the logic density requirements. Ensure the design fits within the 128 I/O lines available on the 176-pin package. Consider the 322 MHz performance limit against system clock speeds. Verify voltage compatibility with the target 3.3V supply domain typical for this family.

Complex Programmable Logic Devices Part Context

This part is part of the ispMACH 4000V family, which blends Lattice's ispLSI 2000 and ispMACH 4A architectures. It focuses on high performance and low power consumption. The family offers flexibility through its Global Routing Pool and Output Routing Pool, facilitating first-time-fit success and pin-out retention during migration.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other members of the ispMACH 4000V family with compatible pinouts and macrocell counts, such as the LC4384V series variants. Cross-family replacements like the LC4000ZE series offer lower power but different performance characteristics. Verify functional equivalence before substitution.
