89HPES16T4ZHBCG

Specialized Overview

The 89HPES16T4ZHBCG is a PCI Express I/O expansion switch manufactured by Renesas Electronics. It features sixteen PCIe Gen1 lanes and seven switch ports, supporting root-to-peripheral and peer-to-peer data transfers. The device utilizes an internal buffering and flow control credit system optimized for maximum bandwidth and large payloads. It operates on a 3.3V supply voltage and is housed in a 288-SBGA package with dimensions of 23x23 mm. This component is designed for low latency and low power consumption applications.

Specialized Feature Summary

• Provides high-performance I/O expansion and switching functions between a PCIe upstream port and six downstream ports.
• Supports peer-to-peer switching capabilities between downstream ports for efficient data routing.
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payload sizes.

Specialized Applications

• PCI Express I/O expansion systems
• System interconnect switching
• Root-to-peripheral data transfer architectures

Specialized Procurement Notes

Verify the exact suffix ZHBCG against official Renesas documentation to confirm pinout and electrical specifications. Check current lifecycle status as this series may be obsolete or subject to discontinuance notifications. Ensure compatibility with existing PCB layouts due to the specific SBGA-288 package requirements.

Specialized Selection Notes

Select this component when sixteen PCIe Gen1 lanes are required for I/O expansion. Consider the 288-SBGA package size for board space constraints. Evaluate thermal management needs given the 3.3V operation. Confirm that the non-blocking architecture meets the throughput requirements of the target application.

Specialized Part Context

This part belongs to the PRECISE family of PCI Express switches from Renesas. It is related to other models like the 89HPES16T4G2ZBBX8 and 89HPES16T4AG2ALGI within the same product line. These devices share similar architectural features but differ in packaging and specific interface configurations.

Specialized Replacement Considerations

Check for direct substitutes within the 89HPES16T4G2 series. Verify if alternative packages such as FCBGA are available from Renesas. Consult official EOL notices for recommended replacement parts if this specific suffix is discontinued.
