Product details
Overview
XIO3130IZHC from Texas Instruments is a PCI Express-to-PCI/PCI-X bridge IC enabling legacy PCI/PCI-X peripherals to connect to PCIe root complexes. It implements a 1-lane PCIe upstream port (2.5 Gbps per lane), supports 32-bit/33 MHz PCI and 64-bit/66 MHz PCI-X 1.0, and integrates serial EEPROM interface for configuration storage. Used in industrial control backplanes and embedded server I/O expansion.
For engineers reviewing the XIO3130IZHC datasheet, XIO3130IZHC pinout, XIO3130IZHC application, or XIO3130IZHC equivalent, key selection criteria include PCIe-to-PCI-X bridging capability, hot-plug support, integrated GPIOs, and TI's proprietary register set for system-level control and error reporting.
Technical Context
The XIO3130IZHC implements a transparent bridge architecture with full PCI Express 1.0a compliance, supporting both upstream (root complex-facing) and downstream (legacy device-facing) transaction translation. It handles address mapping, endian conversion, and coherency for memory-mapped and I/O space accesses between PCIe and PCI/PCI-X domains.
It features dedicated hardware for PCI Hot Plug management-including PWRGDn monitoring, HP_INTX signaling, debounce circuits, and PME_Turn_Off/PME_To_Ack message generation-alongside configurable power management states (L0s, L1, L2/L3 Ready) and Advanced Error Reporting (AER) registers for uncorrectable/correctable error tracking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCIe-to-PCI/PCI-X bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PLX Technology PEX8112-AA66BC | PCIe 1.0a x1 upstream, supports only PCI 32-bit/33 MHz (no PCI-X); lacks integrated GPIO banks and AER registers. | Targeted at cost-sensitive, non-hot-plug consumer or lab environments where legacy PCI-only support suffices. | Select when PCI-X compatibility and advanced error reporting are not required; lower BOM cost but reduced feature set. |
| Pericom PI7C9X2G304SV | PCIe 2.0 x2 upstream (5.0 Gbps/lane), supports PCI-X 133 MHz; includes built-in spread-spectrum clocking and enhanced power gating. | Designed for higher-bandwidth telecom and storage applications requiring faster legacy bus speeds and improved EMI control. | Choose for future-proofing and higher throughput; requires PCIe 2.0 root complex and different layout constraints than XIO3130IZHC. |
Compared with PEX8112-AA66BC and PI7C9X2G304SV, the XIO3130IZHC uniquely balances PCI-X 66 MHz support, integrated hot-plug hardware, and TI-specific register-level control-making it optimal for industrial backplanes where reliability, configurability, and legacy bus speed matter more than raw bandwidth.

FAQ
What is the primary function of the XIO3130IZHC?
The XIO3130IZHC is a PCI Express-to-PCI/PCI-X bridge IC that enables legacy PCI and PCI-X peripherals to operate on modern PCIe-based host systems. It performs real-time protocol translation, address mapping, and timing synchronization between the two bus domains. The XIO3130IZHC supports hot-plug operation, integrated GPIO control, and Advanced Error Reporting-making it suitable for industrial and telecom infrastructure where backward compatibility and system robustness are essential.
Does the XIO3130IZHC support PCI-X 66 MHz operation?
Yes, the XIO3130IZHC fully supports PCI-X 1.0 at 64-bit/66 MHz, as confirmed in Section 2.1 (Description) and Table 6-2 (Recommended Operating Conditions) of the SLLS693F datasheet. This capability allows it to interface with high-performance legacy peripherals such as RAID controllers and network interface cards requiring PCI-X bandwidth, distinguishing it from bridges limited to standard PCI 33 MHz.
How does the XIO3130IZHC handle hot-plug events?
The XIO3130IZHC implements hardware-based PCI Hot Plug management per the PCI Hot Plug Specification 1.0. It monitors PWRGDn for power-rail stability, asserts HP_INTX# for OS notification, and executes controlled power-up/down sequences-including surprise-removal handling and PME_Turn_Off messaging. These functions are managed by dedicated internal logic, eliminating the need for external hot-plug controllers when using the XIO3130IZHC in compliant designs.
What type of serial EEPROM interface does the XIO3130IZHC provide?
The XIO3130IZHC includes an I²C-compatible 2-wire serial bus interface (SCL/SDA) supporting external EEPROMs from 2 kbit to 16 kbit capacity. As detailed in Section 3.4, this interface stores critical configuration data-including Vendor ID, Subsystem ID, and bridge initialization parameters-and is accessed automatically during power-up to configure the device before enumeration.
Is the XIO3130IZHC compatible with PCIe 2.0 or later root complexes?
The XIO3130IZHC is compliant with PCI Express Base Specification 1.0a only and operates at 2.5 Gbps per lane (Gen1). It is backward compatible with PCIe 2.0 and 3.0 root complexes in Gen1 mode but does not negotiate higher speeds. Systems requiring Gen2 or Gen3 bandwidth must use alternative bridges; the XIO3130IZHC remains appropriate where Gen1 throughput and legacy bus support are sufficient, as in many industrial and telecom applications.
