Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '5' against the datasheet to confirm the 5 ns propagation delay specification. Ensure the 44-TQFP package dimensions match the PCB footprint requirements. Confirm that the commercial temperature range (0°C to 90°C) meets the operational environment constraints before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when 64 macrocells are sufficient for the design logic density. The 5 ns delay suits moderate-speed digital control tasks. Compare against the LC4064V-25T44C if higher performance (2.5 ns delay, 400 MHz max frequency) is required within the same package and pin count.

Complex Programmable Logic Devices Part Context

This part is part of the ispMACH 4000V series, which blends ispLSI 2000 and ispMACH 4A architectures. It offers low power consumption with a 1.8V core while maintaining high performance through SuperFAST technology. The family provides flexibility for migration between different density devices within the same package options.
