PI7C8150BNDI - Async 2-Port PCI Bridge | Diodes Incorporated
MPN: PI7C8150BNDI ✓ نشطPI7C8150BNDI نظرة عامة
A PCI bridge is an interface IC that connects one PCI Local Bus segment to another while coordinating bus ownership, transactions, arbitration, and protocol translation. Within the product hierarchy, the PI7C8150BNDI is a PCI interface controller, a bridge device, and an interface IC used in legacy PCI computer and industrial expansion systems. Its asynchronous architecture supports independently timed bus segments, which can help isolate traffic and extend usable system topology compared with placing additional loads directly on one shared PCI bus.
Key verified features include asynchronous operation, two PCI ports, a 32-bit PCI data path, and support for PCI Local Bus Specification Revision 2.2. The device is identified by distributor listings as the PI7C8150BNDI 256-PBGA variant and as a 2-port, 32-bit PCI bridge. These characteristics distinguish it from ordinary endpoint devices because the bridge participates directly in PCI bus arbitration and forwards transactions between two host or peripheral bus segments.
Technically, the bridge is intended to bridge PCI Local Bus domains rather than operate as a memory controller, serial transceiver, or conventional parallel processor interface. The asynchronous design is significant in systems where the two PCI segments do not share identical timing or loading conditions. Exact clock frequencies, voltage limits, transaction throughput, arbitration timing, reset requirements, and electrical characteristics were not included in the supplied verified data and therefore are not asserted here.
Typical uses include industrial computers, embedded PCI expansion systems, test equipment, communications appliances, and legacy PCI-compatible platforms that require an additional bridged bus segment. In these applications, the bridge can separate devices onto a second PCI bus and reduce direct electrical loading on the primary segment. System designers must still validate electrical timing, firmware initialization, interrupt routing, and platform support before deployment.
A primary design consideration is software and firmware compatibility. Because the device bridges an established PCI Local Bus architecture, operating-system support, BIOS or device-tree configuration, interrupt topology, and vendor reference designs must be confirmed for the target platform. Hardware review should also include the manufacturer's PI7C8150B documentation and the exact pin and layout requirements associated with the BNDI package suffix.
This product page combines verified manufacturer and distributor facts, current sourcing information, structured technical context, and explicit data-gap markers. It is intended to help engineers evaluate the PI7C8150BNDI for legacy PCI bridging applications while clearly separating published facts from parameters that still require manufacturer-document review.

PI7C8150BNDI مناسب لـ 6 التطبيقs: Industrial PCI Expansion, Embedded PCI Controller Systems, Industrial Test Equipment, Communications Appliances, PCI Compatibility Platforms, Multi-Card Computer Systems.
Industrial PCI Expansion
The PI7C8150BNDI fits industrial computer designs that need to divide a PCI Local Bus into two independently operated segments. Its verified 2-port, 32-bit architecture and asynchronous operation allow devices on the downstream segment to communicate through the bridge rather than sharing the primary segment's complete load. This arrangement can simplify topology when multiple legacy PCI cards must be isolated from one bus. The design must use the official 256-PBGA land pattern and confirm firmware initialization, interrupt routing, and platform support for PCI Local Bus Specification Revision 2.2.
موصى به
Embedded PCI Controller Systems
The PI7C8150BNDI is applicable to embedded and communications equipment that retains PCI-compatible expansion hardware but requires a bridged bus arrangement. Its 32-bit PCI interface, two ports, and asynchronous operation allow a system controller and a secondary set of PCI peripherals to operate across separate bus segments. The principal benefit is reduced direct loading on one PCI segment and a clearer separation of downstream traffic. Firmware support, interrupt topology, timing margins, and electrical limits must be validated against the manufacturer's PI7C8150B documentation before hardware release.
موصى به
Industrial Test Equipment
The PI7C8150BNDI can serve in test and measurement equipment that uses PCI-compatible instrumentation modules. Bridging a separate measurement-device segment from the primary host bus can provide cleaner bus organization and reduce contention among multiple instruments. Because the verified data confirms an asynchronous 2-port, 32-bit PCI bridge rather than a dedicated measurement interface, the part must pair with appropriate acquisition or control hardware. Engineers should confirm supported PCI specification revision, bus speed, reset behavior, interrupts, and the manufacturer's reference design before integration.
موصى به
Communications Appliances
The PI7C8150BNDI is appropriate for legacy communications appliances that retain one or more PCI expansion cards. A 2-port asynchronous bridge can connect the primary system bus to a secondary PCI segment carrying network, storage, or signal-processing adapters. The 32-bit PCI width and Revision 2.2 target position the device for conventional parallel PCI architecture rather than modern serial fabrics. System integrators must verify operating-system driver support, interrupt routing, firmware configuration, and the unverified supply, timing, and temperature limits before production deployment.
موصى به
PCI Compatibility Platforms
The PI7C8150BNDI can support legacy PCI compatibility platforms that need a transparent bridge between two bus domains. Its asynchronous 2-port configuration permits the two sides to operate without requiring identical timing assumptions, while its 32-bit PCI interface matches conventional PCI Local Bus data paths. This is useful when an existing PCI subsystem must be retained inside a larger control system. Integration is not automatic: the platform must correctly initialize the bridge, mask and route interrupts, and use the exact 256-PBGA footprint prescribed by Diodes Incorporated.
موصى به
Multi-Card Computer Systems
The PI7C8150BNDI is useful in older computer and peripheral systems that install more PCI cards than one shared segment can support cleanly. Dividing the cards between two segments behind a 32-bit asynchronous bridge can improve bus organization and isolate downstream transactions from the host segment. The solution remains tied to PCI Local Bus Specification Revision 2.2 and therefore requires compatible host firmware, device drivers, interrupt handling, and physical implementation. Exact performance improvement depends on traffic loading and cannot be quantified without the missing timing and throughput specifications.

ملاحظات التصميم
Use the manufacturer's exact 256-PBGA land pattern and escape-routing guidance rather than deriving it from the 17 mm by 17 mm body size. The verified data does not identify individual balls, pad dimensions, solder-mask rules, or exposed-pad behavior, so the current mechanical drawing and datasheet must be treated as mandatory layout inputs.
Do not select rail capacitance, bulk capacitance, or power-loss limits from generic PCI assumptions. Supply-voltage limits, current consumption, rail sequencing, and decoupling requirements were not included in the verified data. Obtain the PI7C8150B datasheet's electrical characteristics and reference layout, then verify them against the host platform's power budget and PCI specification implementation notes.
A matching BGA body size does not establish pin compatibility, and the PI7C8150B family name does not prove that another ordering code is interchangeable. Do not substitute a candidate without checking all 256 ball assignments, voltage ratings, clock limits, asynchronous timing, reset behavior, and bridge functionality. No verified drop-in alternative was identified in the supplied cross-reference evidence.
Plan the two PCI segments as separate routed domains and preserve the manufacturer-recommended topology for arbitration, interrupt routing, and reference planes. Keep the bridge and its required support components positioned to minimize trace length on sensitive PCI signals. Exact trace-length, impedance, and layer-stack requirements remain unavailable and must be taken from the official documentation.
Platform validation must include firmware enumeration, interrupt routing, bus ownership, reset behavior, and compatibility with the target operating system. The verified information establishes PCI Local Bus Specification Revision 2.2 support but does not list operating systems, BIOS requirements, maximum transfer rate, or reference designs. Treat those items as unresolved rather than assuming conventional PCI behavior.
معلومات الامتثال
The supplied verified snippets do not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for PI7C8150BNDI. Compliance must be confirmed from current Diodes Incorporated documentation for the exact ordering code.
