Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T176' against official Lattice documentation, as standard datasheets often list 'TN176' for the TQFP-176 industrial grade variant. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly. Ensure the source provides valid RoHS compliance documentation and traceability records for the manufacturing lot.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires moderate density with guaranteed high-speed performance in harsh environments. Compare against the LC4256V-5 series if lower speed requirements allow for cost optimization. Ensure the target application fits within the 128 I/O limit and that the 3.3 V core voltage aligns with system power rails.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, designed for super-fast, high-density applications. It combines non-volatile configuration memory with high-performance logic blocks. The family is known for supporting both 3.3 V and 2.5 V/1.8 V I/O standards, facilitating mixed-voltage system integration without external level shifters.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other members of the LC4256V family with compatible package options, such as the LC4256V-75TN176I. Verify that any substitute maintains the same 7.5 ns speed grade and industrial temperature rating. Cross-reference logic resource availability and I/O pin assignments to ensure functional equivalence.
