Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix TN144 indicates the TQFP-144 package variant. Confirm the -75 speed grade corresponds to the 7.5 ns delay specification. Ensure the 'I' suffix denotes the industrial temperature range required for your application environment. Cross-reference the manufacturer part number with official Lattice documentation to confirm current production status and availability constraints.

Complex Programmable Logic Devices Selection Notes

Select this component when 256 macrocells are sufficient for the design complexity. The 3.3 V operating voltage makes it suitable for legacy or mixed-voltage systems. Consider the TQFP-144 package if through-hole or standard surface mount assembly is preferred over BGA options. Evaluate the 322 MHz maximum frequency against system timing requirements to ensure adequate performance margins.
