Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'V' against official Lattice documentation to confirm voltage grade or temperature range specifications, as datasheet details for this exact variant may require direct manufacturer reference. Ensure compatibility with JTAG programming requirements for in-system programmability.

Complex Programmable Logic Devices Selection Notes

Select this device when 64 macrocells are sufficient for the design logic density. The 400 MHz speed grade suits moderate-speed synchronous designs. Consider the TQFP-48 package constraints for PCB layout. Verify that the 1.8 V core requirement aligns with available power rails, noting the need for level shifting if interfacing directly with 1.8 V logic without 5 V tolerance.
