Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' against official Lattice documentation to confirm industrial temperature rating compliance. Confirm package integrity for the 144-pin TQFP form factor. Check current product status as some variants may be discontinued or subject to last-time buy notices. Ensure ESD handling protocols are followed during storage and assembly.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require moderate logic density with fast propagation delays. Compare against the LC4256ZE series if lower power consumption at 1.8 V is required instead of the standard 3.3 V operation. Evaluate pin count requirements to ensure the 96 I/O limit meets system connectivity needs. Consider the 5 ns delay specification for timing-critical synchronous applications.
