PI7C8150BND - 2-Port 32-Bit PCI Bridge | Diodes Incorporated
N.º da peça: PI7C8150BND ✓ AtivoPI7C8150BND Visão geral
A PCI-to-PCI bridge is a semiconductor interface controller that connects two conventional Peripheral Component Interconnect bus segments. It belongs to the interface-controller hierarchy, where a PCI bridge translates and arbitrates bus transactions between a host-side primary port and a peripheral-side secondary port. This device adds no external memory or cache to the system; instead, it provides the electrical and protocol interface needed to extend a 32-bit PCI topology.
The PI7C8150B family provides 32-bit primary and secondary ports capable of running to 66 MHz, while the PI7C8150B-33 version is identified as a 33 MHz variant. Other advertised characteristics include asynchronous operation and PCI Local Bus Specification Revision 2.2 support. The PI7C8150BND ordering code is supplied in the 256-pin PBGA package with a 17 mm by 17 mm body, making package compatibility a primary screening criterion when evaluating any proposed replacement.
The bridge architecture is intended for systems that require a secondary PCI segment rather than a compact serial interconnect. Its two independently referenced bus interfaces support legacy PCI topology expansion, while the 32-bit data path accommodates the width used by the PCI Local Bus Specification Revision 2.2. Engineers must still account for platform-specific voltage, clocking, termination, and signal-integrity requirements when integrating the device into a complete motherboard or embedded system.
Typical uses include industrial PCI expansion, data-acquisition equipment, communication appliances, test systems, and embedded controllers that retain a conventional PCI host bus. Because this is a complex 256-pin BGA device, layout requires exact ball assignment, multilayer routing, solid return planes, and careful simultaneous-transition-noise control. Firmware must also enumerate the bridge and configure the secondary bus, so replacing it requires validation beyond comparing the package and nominal clock rate.
For a new design, verify the manufacturer datasheet for voltage domains, I/O standards, clock requirements, reset behavior, electrical characteristics, and the complete ball map before committing a PCB footprint. For a repair, do not assume a related order code is interchangeable: suffix changes can represent package, temperature, lead-free, or speed variations. The verified distributor listings identify the device as a PCI interface IC and provide ordering and availability information, but they do not expose enough technical data to claim unqualified pin compatibility for every related suffix.
This page consolidates manufacturer and distributor findings, verified package information, family-level operating details, sourcing links, and engineering-oriented selection guidance. It separates documented facts from unresolved electrical and mechanical details, allowing engineers to narrow a replacement before performing full datasheet, firmware, and signal-integrity validation.

Aplicações típicas
PI7C8150BND é adequado para 6 aplicaçãos: Industrial PCI Expansion Systems, Data-Acquisition Equipment, Embedded Communication Equipment, Test and Measurement Instruments, Legacy PCI Adapter Cards, PCI-Compatible Network Gateways.
Industrial PCI Expansion Systems
The PI7C8150BND fits industrial expansion systems that retain a conventional PCI topology and require a second 32-bit bus segment. Its documented 2-port asynchronous architecture separates primary and secondary PCI traffic, while operation up to 66 MHz supports systems designed around PCI Local Bus Specification Revision 2.2. The device can bridge an existing host controller to data-acquisition, communication, or motion-control cards without changing the external bus architecture. Engineering validation must cover the 256-PBGA ball map, supply domains, clocking, reset sequencing, and firmware enumeration. Because this is a legacy parallel interface, the PCB also needs short, impedance-controlled routes, solid return planes, and careful accommodation of shared-bus timing.
Recomendado
Data-Acquisition Equipment
PI7C8150BND can support a data-acquisition chassis whose plug-in cards communicate over a secondary PCI segment. The bridge's documented 32-bit primary and secondary ports and 66 MHz maximum operating frequency provide a direct match for PCI Revision 2.2-based acquisition systems. An instrument can place the bridge between a host computer's primary PCI bus and an acquisition card while firmware enumerates the new bus segment. The design tradeoff is that shared parallel buses require disciplined layout, termination, and loading analysis rather than modern serial equalization. Engineers should validate channel timing, interrupt routing, bus arbitration, and the exact 17 mm by 17 mm 256-PBGA land pattern before releasing a new board.
Recomendado
Embedded Communication Equipment
The PI7C8150BND is appropriate for embedded communication appliances that must retain PCI compatibility with existing protocol cards or accelerator modules. Its two 32-bit ports support asynchronous bridge operation up to 66 MHz, allowing a primary host interface and secondary expansion bus to operate within the documented PI7C8150B limits. Such a configuration can extend legacy networking, storage, or industrial-control adapters without replacing the established host architecture. Integration risk is concentrated in the complex 256-PBGA package and the shared nature of PCI signaling. Layout review should include layer-stack compatibility, via and escape routing, clock jitter margins, termination values, and power sequencing. Software must also support bus enumeration and correctly configure the bridge after reset.
Recomendado
Test and Measurement Instruments
The PI7C8150BND can bridge a legacy PCI measurement card into a test instrument or laboratory controller that uses a PCI host segment. The documented 2-port asynchronous design supports 32-bit primary and secondary interfaces, while the 66 MHz operating limit aligns with PCI Revision 2.2 system requirements. This allows instrument designers to preserve established acquisition or stimulus modules while implementing a host-controller topology around them. The main engineering concern is the device's dense 256-PBGA footprint: escape routing, plane continuity, decoupling, and thermal performance can constrain the PCB stack-up. Firmware validation should cover enumeration, resource allocation, interrupt behavior, and transfers in both directions. Lifecycle and long-term supply confirmation remain advisable for test platforms with long service lives.
Recomendado
Legacy PCI Adapter Cards
PI7C8150BND can be used within legacy PCI adapter or embedded expansion designs that need to expose a secondary conventional PCI bus. Its documented 32-bit dual-port architecture and operation up to 66 MHz make it relevant to systems maintaining PCI Local Bus Specification Revision 2.2 compatibility. A bridge arrangement permits an existing host platform to reach another bank of plug-in devices while retaining a familiar parallel-bus software model. The available evidence does not include the complete electrical table or ball map, so a new implementation must use the manufacturer datasheet for voltage domains, timing, clock requirements, and pin assignments. PCB signoff should include bus-segment topology, termination, maximum loading, connector pin assignments, and enumeration behavior under abnormal bus conditions.
Recomendado
PCI-Compatible Network Gateways
The PI7C8150BND is applicable to network gateways and protocol translators that need to bridge legacy PCI expansion devices into an embedded host platform. Its asynchronous 2-port interface can separate a 32-bit primary PCI connection from a secondary segment while retaining the documented 66 MHz family capability. This topology can support legacy communication, storage, or factory-control modules without forcing a complete platform conversion to a serial interconnect. Design verification should focus on electrical compatibility, clock-domain behavior implied by asynchronous operation, reset integration, and the 256-PBGA assembly process. Firmware must enumerate the bridge consistently and ensure the operating system does not exceed the 66 MHz limit or the secondary segment's allowed device loading. Exact suffix behavior must be confirmed from the ordering guide.

Notas de projeto
Treat the 256-PBGA layout as a constrained high-speed design rather than a generic BGA escape problem. Compare the manufacturer land pattern and ball map against the PCB library before routing, preserve the documented 17 mm by 17 mm package geometry, and allocate through-vias beneath the device according to the manufacturer's assembly guidance. The supplied results do not provide a complete pinout or recommended PCB stack-up, so both must be obtained from the manufacturer datasheet before release.
Validate the complete PCI bus topology, including the 32-bit primary and secondary paths, termination, trace length, loading, connector reach, and clock routing. The documented asynchronous operation and 66 MHz capability do not by themselves guarantee system-level timing margin. Use the manufacturer's electrical characteristics and reference design to establish impedance, topology, and routing rules, then verify skew and signal integrity during hardware bring-up.
Do not substitute PI7C8150BND, PI7C8150BNDI, PI7C8150BNDE, PI7C8150BNDIE, or a -33 variant based on the shared family name alone. Confirm the ordering suffix, exact ball assignments, supply voltages, clock maximum, I/O standard, temperature grade, and lifecycle status. In particular, the -33 device is limited to 33 MHz rather than the documented 66 MHz of the standard family and can therefore alter system performance.
Use the manufacturer power specification to define every voltage rail, sequencing requirement, decoupling network, and current budget. The verified source snippets do not contain supply-voltage or quiescent-current values, so neither can be responsibly inferred from the 66 MHz PCI clock or package size. Prototype power-up testing should include reset behavior and rail timing, with measurements taken on the bridge and its connected PCI segment.
Informações de conformidade
The supplied verified results do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because the device is a general-purpose legacy PCI interface IC, but no formal qualification statement was provided.
