Specialty Logic Procurement Notes

Verify the specific suffix ZALR against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Confirm that the 176-NFBGA footprint matches the target PCB layout. Ensure compatibility with the required 1.25V, 1.35V, or 1.5V power rails during the design phase.

Specialty Logic Selection Notes

Select this component when designing DDR4 memory architectures requiring registered buffers with parity support. It is suitable for environments demanding operation across the industrial temperature range of -40°C to +95°C. Consider the 176-NFBGA package size constraints and the availability of 1.35V or 1.5V power supplies in the target system.
