Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to 90°C TJ) as defined in the official datasheet. Confirm the package type matches the required 176-TQFP footprint. Ensure design compatibility with the 1.8 V core voltage requirements. Check for any recent Product Change Notices regarding marking or packaging updates. Validate that the supplier provides genuine Lattice Semiconductor components.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are sufficient for the design complexity. Choose the 35 speed grade if a 3.5 ns propagation delay meets timing requirements. Opt for the TN176C package variant only if the 176-pin TQFP outline fits the board layout. Consider the 5 V tolerant I/O feature if interfacing with older 5 V peripherals is necessary. Evaluate the 1.8 V core requirement against available power rails.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4000V family, which blends ispLSI 2000 and ispMACH 4A architectures. The family is designed for SuperFAST performance with low power consumption. The LC4512V variant represents the highest density option in this specific series, offering 512 macrocells. It utilizes global routing pools to ensure timing predictability and first-time-fit success.

Complex Programmable Logic Devices Replacement Considerations

The LC4512Z-35TN176C is a verified substitute within the same family, offering identical logical functionality but potentially differing in voltage specifications or temperature grades. Verify pinout compatibility before substitution. Ensure the replacement part supports the required 1.8 V core voltage and 5 V tolerant I/O characteristics. Confirm package dimensions match the existing PCB footprint.
