Description
PI2PCIE2212ZHEX is a PCIe-to-PCI bridge IC (PI2PCIE family, originally from Pericom, now Renesas). It sits between a PCIe host/controller (upstream) and a PCI/PCI-X bus (downstream), translating PCIe transactions to PCI on the downstream side. Uses include adding PCI slots to a PCIe system or connecting legacy PCI devices to a PCIe backbone.
Key points to check in the datasheet:
- Upstream PCIe speed (Gen1/Gen2) and lane configuration
- Downstream PCI bus type (32-bit PCI/PCI-X compatibility)
- Number of downstream ports and windowing (memory and I/O)
- DMA/bridge capability, interrupt bridging, and configuration space handling
- Power, thermal, ESD considerations, and supported package (ZHEX)
For exact features and pinout, consult the official datasheet and evaluation boards from Renesas/Pericom. If you share the revision or a link, I can summarize the exact specs.

Equivalent
There’s no published direct 1:1 cross reference for PI2PCIE2212ZHEX. The practical approach is to use another 2-port PCIe switch from a different vendor. Closest equivalents: Broadcom/PLX PEX8712 and PEX8722 (2‑port PCIe Gen 2 switches). When selecting, verify package, PCIe generation, and port topology. For an exact cross-reference, consult Pericom/Broadcom distributors or their tech support.
Pinout
Pin count: 48 pins (ZHEX package).
Function: PCIe switch/bridge – a 2-downstream, 1-upstream PCI Express switch (one upstream port and two downstream ports) used to fan-out PCIe lanes to two devices.
