Product details
Overview
XIO3130INMH from Texas Instruments is a PCI Express-to-PCI/PCI-X bridge IC that implements a 1-lane PCIe upstream port and dual 32-bit/33-MHz PCI downstream ports, supporting transparent bridging with full hot-plug capability, 256-byte maximum payload size, and integrated serial EEPROM interface. It operates at 1.2-V core voltage and 3.3-V I/O, enabling legacy PCI expansion in modern PCIe-based embedded and industrial systems.
For engineers reviewing the XIO3130INMH datasheet, XIO3130INMH pinout, XIO3130INMH application, or XIO3130INMH equivalent, key selection criteria include PCIe Gen1 compliance, dual-PCI bus arbitration support, integrated MSI message handling, power-up sequencing control, and TI's proprietary register-level switch configuration for system-level PCIe-to-PCI interconnect.
Technical Context
The XIO3130INMH implements a root-complex–compatible upstream PCIe port (x1) and two independent downstream PCI buses (PCI-A and PCI-B), each with dedicated address/data/control signals and configurable latency timers. It supports PCI Express Base Specification v1.0a and PCI Local Bus Specification v2.3, including Type 0/1 configuration space mapping and Advanced Error Reporting (AER).
Power management includes L0s/L1 entry/exit control, PME signaling, and programmable link PM latency registers per port. The device integrates a 2-wire serial bus controller for external EEPROM access, GPIO terminals for hot-plug presence detection and slot reset control, and TI-specific registers for global chip and switch-level configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCIe-to-PCI bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PLX Technology PEX8112-AA50BCF | Single-lane PCIe upstream, single 32-bit/33-MHz PCI downstream port; no integrated EEPROM controller; requires external configuration PROM. | Limited to single-PCI-peripheral use cases; lacks dual-bus arbitration and native hot-plug interrupt signaling. | Select when only one legacy PCI device is needed and external configuration storage is acceptable. |
| Pericom PI7C9X2G304SV | PCIe Gen2 x2 upstream, quad PCI downstream ports; 1.5-V core; supports larger payload sizes (512 bytes) and higher bandwidth. | Targets higher-throughput applications; not pin- or register-compatible; requires different power and layout design. | Choose for future-proofing or multi-peripheral systems where Gen2 bandwidth and additional PCI lanes are required. |
Compared with the PEX8112-AA50BCF and PI7C9X2G304SV, the XIO3130INMH uniquely balances dual-PCI support, integrated EEPROM, and TI's mature hot-plug implementation within a Gen1-compliant, thermally optimized NFBGA package-making it optimal for cost-sensitive, space-constrained industrial retrofits.

FAQ
What is the primary function of the XIO3130INMH in a system architecture?
The XIO3130INMH serves as a transparent PCI Express-to-PCI/PCI-X bridge, enabling legacy PCI peripherals to connect to modern PCIe root complexes. It handles protocol translation, address decoding, bus arbitration, and configuration space mapping-allowing existing PCI cards to operate without driver changes. Its dual downstream PCI ports support independent bus operation, making the XIO3130INMH ideal for multi-peripheral expansion in industrial and medical systems.
Does the XIO3130INMH support hot-plug functionality, and how is it implemented?
Yes, the XIO3130INMH fully implements PCI Hot Plug v1.0, including hardware-level detection of card insertion/removal, PWRGDn feedback monitoring, HP_INTX# interrupt generation, and surprise-removal recovery. It uses dedicated strapping terminals and internal state machines to manage power sequencing and link retraining-ensuring safe, standards-compliant hot-plug operation without host software intervention. This capability is integral to the XIO3130INMH's role in field-serviceable systems.
What package type and thermal characteristics does the XIO3130INMH use?
The XIO3130INMH is packaged in a 256-pin NFBGA (NMH) with 17 mm × 17 mm footprint and 1.0-mm ball pitch, featuring an exposed thermal pad for enhanced heat dissipation. Its thermal resistance (θJA) is 26.5°C/W under JEDEC JESD51-7 conditions, and it operates over –40°C to +85°C ambient temperature. These characteristics make the XIO3130INMH suitable for convection-cooled industrial enclosures where airflow is limited.
How does the XIO3130INMH handle configuration data storage?
The XIO3130INMH integrates a 2-wire serial bus controller compatible with standard I²C EEPROMs (e.g., 24LC02B), allowing nonvolatile storage of vendor ID, subsystem ID, and custom configuration registers. Configuration data is loaded automatically at power-up, eliminating the need for external PROM or host-initiated programming. This built-in capability simplifies system bring-up and ensures consistent behavior across XIO3130INMH units in production.
Is the XIO3130INMH compatible with PCIe Gen2 or higher link speeds?
No, the XIO3130INMH complies exclusively with PCIe Base Specification v1.0a and supports only Gen1 (2.5 GT/s) link speeds on its upstream port. It does not negotiate Gen2 or Gen3 rates, nor does it support ASPM L0s/L1 power states beyond those defined in v1.0a. Systems requiring higher bandwidth must use newer bridge ICs; however, the XIO3130INMH remains optimal for cost-sensitive, Gen1-constrained applications where dual-PCI support and hot-plug reliability are critical.
