Overview
The 89HPES24N3AZCBXI is a PCI Express I/O expansion switch manufactured by Renesas Electronics. It provides 24 PCIe Gen1 lanes across three switch ports, supporting root-to-peripheral and peer-to-peer data transfers. The device features internal buffering and flow control credits optimized for maximum bandwidth and large payloads. It operates with low latency and low power consumption, designed to deliver high-performance switching functions between an upstream port and downstream ports.
Feature Summary
- Provides high-performance I/O expansion and switching capabilities between PCIe upstream and downstream ports.
- Supports both root-to-peripheral (upstream-to-downstream) and peer-to-peer (downstream-to-downstream) data transfer architectures.
- Features internal buffering and flow control credits optimized for maximum bandwidth and large payload sizes.
Applications
- PCIe I/O expansion systems requiring high-bandwidth connectivity
- Server and storage infrastructure needing efficient data routing
- Embedded systems utilizing peer-to-peer communication
Procurement Notes
Verify the exact suffix ZCBXI against official Renesas documentation to confirm package type and temperature grade. Confirm End-of-Life status and availability through authorized distributors, as this component may be discontinued or subject to limited supply constraints.
Selection Notes
Select this component when a 24-lane, 3-port PCIe Gen1 switch is required for I/O expansion. Ensure system design supports the specific pinout and thermal requirements of the ZCBXI package variant. Verify compatibility with existing PCIe Gen1 controllers and software drivers provided by the manufacturer.
Part Context
This part belongs to the 89HPES24 series of PCIe switches from Renesas (formerly IDT). It is functionally related to variants like 89HPES24NT3ZBBX and 89HPES24N3A1ZCBX8, differing primarily in packaging and specific ordering suffixes. The series targets high-performance I/O expansion applications.
Replacement Considerations
Check for direct substitutes within the 89HPES24 family such as 89HPES24N3A1ZCBX8. Verify pin-to-pin compatibility and electrical specifications before substitution. Consult Renesas engineering support for validated replacement options if the exact suffix is unavailable.
