Product details
Overview
XIO3130ZHC from Texas Instruments is a PCI Express-to-PCI/PCI-X bridge IC that implements a single upstream PCIe x1 port and dual downstream PCI/PCI-X 32-bit 33/66-MHz buses. It supports hot-plug, advanced error reporting, MSI interrupt delivery, and serial EEPROM configuration. Used in industrial embedded systems requiring legacy PCI device integration into modern PCIe host platforms.
For engineers reviewing the XIO3130ZHC datasheet, XIO3130ZHC pinout, XIO3130ZHC application, or XIO3130ZHC equivalent, key selection criteria include PCIe Gen1 x1 upstream compatibility, dual 32-bit PCI/PCI-X downstream support, integrated hot-plug controller logic, MSI capability, and TI's proprietary register-level switch control architecture.
Technical Context
The XIO3130ZHC implements a transparent bridge with full PCI Express Base Specification v1.0a compliance for upstream link and PCI Local Bus Specification v2.3 / PCI-X Specification v1.0a compliance for downstream buses. It handles address translation, transaction routing, and flow control between PCIe and PCI domains without firmware intervention.
Its internal architecture includes dedicated PCIe PHY layer, configurable GPIOs (A–D), serial EEPROM interface (I²C-compatible), and comprehensive power management with L0s/L1 entry/exit control. All configuration registers-including PCI Express Capability, Advanced Error Reporting, and TI-specific switch control-are memory-mapped and accessible via PCIe config space or MMIO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI Express-to-PCI bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PLX Technology PEX8112-AA66BCF | Single-lane PCIe upstream, single 32-bit PCI downstream; lacks dual PCI buses and integrated hot-plug controller. | Suitable for simpler expansion where only one legacy PCI device is needed; no slot-level power management. | Select when cost and footprint are prioritized over dual-bus flexibility and autonomous hot-plug operation. |
| Pericom PI7C9X2G304SV | PCIe Gen2 x4 upstream, quad 32-bit PCI downstream; higher bandwidth but larger package and greater power draw. | Targeted at high-throughput test systems requiring >266 MB/s aggregate PCI bandwidth; not pin-compatible. | Choose for future-proofing and multi-slot scalability; requires revised PCB layout and thermal design. |

FAQ
What is the primary function of the XIO3130ZHC?
The XIO3130ZHC is a PCI Express-to-PCI/PCI-X bridge IC that connects a PCIe Gen1 x1 upstream port to two independent 32-bit PCI/PCI-X downstream buses. It enables legacy PCI devices to operate within modern PCIe-based systems without software or driver changes. The XIO3130ZHC handles protocol translation, address mapping, and transaction routing transparently, making it ideal for industrial and medical equipment upgrades.
Does the XIO3130ZHC support hot-plug functionality out of the box?
Yes, the XIO3130ZHC integrates a full PCI Hot Plug controller compliant with PCI Hot Plug Specification v1.0. It manages power sequencing, presence detection, and slot reset autonomously using dedicated HP_INTX#, PWRGDn, and PRSNTn signals. No external hot-plug ASIC or FPGA logic is required-reducing design complexity and BOM cost. This capability is confirmed in Section 5 of the XIO3130ZHC datasheet.
Can the XIO3130ZHC be configured without external firmware?
Yes, the XIO3130ZHC supports configuration via an external serial EEPROM connected through its I²C-compatible SCL_EE/SDA_EE pins. Vendor ID, device ID, subsystem IDs, and capability masks can be stored and loaded automatically at power-up. This eliminates dependency on host BIOS or driver-level initialization, enabling true plug-and-play operation for the XIO3130ZHC in embedded systems.
What interrupt mechanisms does the XIO3130ZHC support?
The XIO3130ZHC supports Message Signaled Interrupts (MSI) with up to 32 vectors, as defined in its PCIe capability structure. It does not rely on legacy INTx lines, avoiding IRQ sharing conflicts and improving interrupt latency predictability. MSI configuration is handled through the MSI Message Control, Address, and Data registers in the XIO3130ZHC's PCIe configuration space, enabling scalable interrupt handling in multi-slot systems.
Is the XIO3130ZHC compatible with PCI-X 66 MHz devices?
Yes, the XIO3130ZHC supports both 33 MHz and 66 MHz operation on each of its two downstream PCI/PCI-X buses, as specified in Section 2.4 and Table 6-2 of the XIO3130ZHC datasheet. It complies with PCI-X Specification v1.0a and maintains full electrical and timing compatibility with 66-MHz PCI-X peripherals, including burst-mode transfers and split transactions.
