89HPES12T3G2ZABCG8

Specialized Overview

The 89HPES12T3G2ZABCG8 is a PCI Express switch interface IC manufactured by Renesas Electronics. It operates on a 3.3V supply voltage and utilizes a 324-CABGA package with dimensions of 19x19 mm. The device supports surface mount installation and belongs to the PRECISE series. It functions as a switch interface component designed for high-performance I/O expansion.

Specialized Feature Summary

• Provides high-performance I/O expansion and switching functions between a PCIe upstream port and two downstream ports
• Supports peer-to-peer switching between downstream ports
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Specialized Applications

• PCIe switch interface applications
• I/O expansion systems
• Root-to-peripheral data transfer architectures

Specialized Procurement Notes

Verify the specific ordering suffix ZABCG8 against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with the 324-CABGA footprint during procurement planning.

Specialized Selection Notes

Select this component when designing systems requiring a three-port PCIe Gen2 switch architecture. Confirm that the design accommodates the 324-CABGA package size and 3.3V power requirements. Validate signal integrity for the specific PCB layout associated with this BGA package.

Specialized Part Context

This part is part of the 89HPES12 family of PCIe switches from Renesas. It shares core switching capabilities with variants like the 89HPES12T3G2 but differs in packaging and commercial/industrial grading indicated by the suffix. It serves as an interconnect solution within the broader PRECISE product line.

Specialized Replacement Considerations

Direct substitutes include other 89HPES12 variants such as 89HPES12T3G2 or 89HPES12N3A1ZCBCG8, provided the package and electrical specifications match the system requirements. Verify pinout compatibility before substitution.
