PI7C9X110BNBE - PCIe-to-PCI Bridge | Diodes Inc.
Teilenummer: PI7C9X110BNBE ✓ AktivPI7C9X110BNBE Übersicht
A PCI Express-to-PCI bridge is an interface controller that translates transactions between PCI Express and parallel PCI signaling. Within the semiconductor hierarchy, it belongs to interface ICs, bus bridges, and computer-interface silicon. A non-transparent bridge provides distinct address windows for the PCI side of the system, making it appropriate when the downstream PCI bus must remain identifiable and isolated from another host domain.
The PI7C9X110BNBE provides a 32-bit PCI data path operating at 66 MHz. Its reversible architecture supports communication in either bridge direction, while the 160-LFBGA package provides a high pin count for the power, ground, and I/O requirements of a wide parallel bus interface. The package uses a 12 mm by 12 mm body and is intended for surface-mount PCB assembly.
The device is identified as a PCI Express-to-PCI non-transparent reversible bridge by the manufacturer. Its primary engineering value is legacy PCI interoperability: it allows a PCI Express host system to retain access to conventional PCI-compatible peripherals without redesigning those peripherals around a newer host interface. This makes it relevant to industrial controllers, test equipment, embedded systems, and legacy expansion platforms that must combine PCIe connectivity with a 32-bit, 66 MHz PCI segment.
Typical deployment places the bridge between a PCIe root complex and a downstream PCI bus. Board-level implementation requires careful routing of the 32-bit PCI data bus, address lines, control signals, reference clock, and power distribution. Although the device presents a high-speed serial PCIe side, the conventional PCI side contains many parallel signals whose length matching, return-path continuity, and termination strategy can materially affect signal integrity.
For new designs, verify the bridge's electrical characteristics, reference-clock requirements, reset behavior, firmware-enumerated resources, operating-temperature limits, and package-specific layout constraints in the manufacturer datasheet. Confirm that the legacy PCI bus topology, device addressing, and software compatibility meet the system requirements before committing the 160-LFBGA layout to production.
This page consolidates the known device identity, package, interface architecture, manufacturer documentation, distribution information, and practical implementation guidance. It also distinguishes verified drop-in replacements from related interface ICs that may serve different electrical or bus requirements.

Typische Anwendungen
PI7C9X110BNBE ist geeignet für 6 Anwendungs: Industrial Controller Legacy PCI Expansion, PCI Express Test Equipment, Embedded System PCI Compatibility, Legacy Instrumentation Interoperability, PCI Express Carrier Board, Data Acquisition and Signal Processing.
Industrial Controller Legacy PCI Expansion
The PI7C9X110BNBE is suitable for an industrial controller that must retain conventional PCI expansion devices while adding a PCI Express host interface. The bridge provides a 32-bit, 66 MHz PCI bus for communication with compatible peripherals while the PCIe side connects to the controller's root complex. Because the downstream segment is non-transparent, its address space can remain separate from another host domain. Deployment should follow the manufacturer reference design, including the required reference clock, reset sequencing, power rails, and all 160 BGA ball assignments.
PCI Express Test Equipment
The PI7C9X110BNBE can bridge a PCIe-based test platform to a 32-bit, 66 MHz conventional PCI instrument or fixture. This arrangement allows older PCI cards, bus analyzers, or acquisition modules to participate in a modern PCIe system without replacing every peripheral. The design must budget the parallel PCI bus's trace length, termination, clock routing, loading, and power integrity. Firmware must also enumerate the non-transparent PCI address window correctly and expose the downstream resources to the host operating environment.
Embedded System PCI Compatibility
An embedded processor platform with PCIe root-port capability can use the PI7C9X110BNBE to communicate with a downstream 32-bit, 66 MHz PCI subsystem. This is useful when retaining established PCI peripherals, controller cards, or field-service hardware is more practical than redesigning each peripheral for PCIe. The bridge acts as a translation and transaction-control device rather than as a general-purpose processor. Board bring-up should confirm reset ordering, clock source behavior, interrupt routing, address decoding, and operating-temperature limits before production release.
Legacy Instrumentation Interoperability
The PI7C9X110BNBE supports a migration path for laboratory and industrial instrumentation that mixes PCIe computing with conventional PCI instruments. Its 32-bit, 66 MHz PCI segment can connect compatible legacy peripherals while the PCIe side links to a newer host or embedded controller. Because the parallel interface carries many timing-sensitive signals, the implementation should follow the manufacturer's board-layout guidance and preserve continuous reference-clock and ground-return paths. Software drivers and operating-system resource enumeration must also be validated against the target instrument set.
PCI Express Carrier Board
A PCI Express carrier board can use the PI7C9X110BNBE to provide a conventional PCI segment for legacy modules while the carrier connects upstream through PCIe. This topology can shorten the development cycle for systems whose mechanical enclosure and expansion ecosystem are already based on PCI cards. The 160-LFBGA device nevertheless requires careful fanout from its fine-pitch ball array, and the carrier must deliver the required supplies with low enough noise for the bridge and attached PCI devices. Signal-integrity and power-integrity validation are essential before system qualification.
Data Acquisition and Signal Processing
The PI7C9X110BNBE is applicable to a mixed data-acquisition system where a modern PCIe processor must access established 32-bit, 66 MHz PCI measurement hardware. The bridge provides reversible, non-transparent connectivity between the two bus domains while retaining compatibility with proven acquisition peripherals. Design validation should include bus-master capability requirements, interrupt latency, DMA behavior, clock tolerance, and address-window isolation. Power sequencing and thermal performance must also be checked under the maximum expected PCI loading rather than only under a lightly populated test configuration.

Wichtigste Unterscheidungsmerkmale
- Reversible non-transparent bridge operation (vs. PI7C9X111SLBFDE)
- Documented 32-bit, 66 MHz conventional PCI interface (vs. PI7C9X2G312GPBNJE)
- 160-LFBGA package provides 160-ball interface density (vs. PI7C9X2G606PRCNJEX)
Designhinweise
Follow the manufacturer land pattern and ball-assignment table for the 160-LFBGA package. Preserve the intended package orientation, inspect the exposed thermal and power balls, and avoid placing disruptive high-speed routes beneath the bridge where they can disturb plane continuity. The 12 mm by 12 mm package requires careful fanout between its fine-pitch balls and the surrounding conventional PCI circuitry.
Treat the 32-bit, 66 MHz PCI bus as a demanding parallel interface. Route the data, address, and control signals with continuous reference planes, minimize branch stubs, match clock distribution, and follow the manufacturer's termination recommendations. Confirm the complete downstream bus topology and worst-case device loading because adding or removing PCI devices can alter timing and signal-integrity margins.
Use the manufacturer's power architecture and sequencing requirements rather than assuming that a general-purpose supply arrangement is sufficient. Verify every required voltage, tolerance, current, ramp sequence, decoupling value, and exposed-ball connection in the datasheet. The bridge and attached legacy PCI peripherals should be evaluated together to ensure their combined current does not overstress the PCB distribution network.
Do not substitute a similarly named PI7C device solely because it performs a related bridge function. Confirm exact ball assignments, supply rails, reference-clock behavior, reset requirements, bus width, operating frequency, transparency mode, and firmware initialization. A drop-in replacement requires all these characteristics to be compatible with the existing PCB and system software.
