Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'ZC' against official Lattice documentation to confirm it denotes the low-power variant compared to the standard 'V' series. Ensure compatibility with existing board layouts for the TQFP-100 footprint. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the latest datasheet for any pinout or electrical characteristic updates.

Complex Programmable Logic Devices Selection Notes

Select this component when 256 macrocells and 64 I/Os are required in a 100-pin surface mount package. Choose the ZC variant over the V series if lower power consumption is a primary design constraint. Ensure the design utilizes the 3.3V core voltage domain. Verify that the 7.5 ns speed grade meets the timing requirements of the target application.
