Procurement Notes

Verify the specific ordering suffix ZCBL8 against official Renesas documentation to confirm package type and environmental compliance. Check current lifecycle status as interface ICs may face discontinuation. Confirm availability through authorized distributors only. Ensure ESD protection protocols are followed during handling due to the fine-pitch BGA packaging.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 systems. Compare against the 89H32NT8BG2ZCHLGI8 variant if non-transparent bridging or different port counts are needed. Verify voltage domain requirements match the 1V/2.5V/3.3V specifications. Ensure board space accommodates the 484-FCBGA footprint.
