Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Lattice Semiconductor distributors or certified partners. Confirm the specific suffix codes match the required package type and temperature grade. Check for end-of-life status, as older CPLD families may have limited availability. Ensure compliance with current RoHS directives if lead-free composition is required for the specific manufacturing process.

Complex Programmable Logic Devices Selection Notes

Select this device when 384 macrocells are sufficient for the logic density requirements. Choose based on the 322 MHz speed grade for timing-critical applications. Consider the 176-pin TQFP footprint for board layout constraints. Evaluate power consumption needs against the 3.3V/2.5V/1.8V I/O flexibility offered by the ispMACH 4000V architecture.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, which blends Lattice's ispLSI 2000 and ispMACH 4A architectures. The family emphasizes high speed and low power while maintaining design flexibility. It is designed for applications requiring reliable, non-volatile programmable logic with easy migration paths from lower-density devices.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000V family with compatible pinouts and macrocell counts, such as the LC4384V-35T176C. Verify that the substitute maintains the same package dimensions and electrical characteristics. Cross-reference with the LC4384C series if speed grades align, though architectural differences may exist.
