PI7C8150BMAE - 66MHz PCI-to-PCI Bridge | Diodes Incorporated
Référence : PI7C8150BMAE ✓ ActifPI7C8150BMAE Présentation
A PCI-to-PCI bridge is an interface controller that extends a PCI local bus through a transparent transaction bridge. In the product hierarchy, this device is a bus controller, interface IC, and ultimately a semiconductor. The primary and secondary ports each operate at 32-bit width, allowing legacy PCI expansion systems, embedded modules, industrial controllers, and data-acquisition equipment to communicate across separate bus domains while preserving the electrical and transaction behavior expected from PCI Revision 2.2 systems.
The verified device family supports asynchronous operation, meaning the primary and secondary interfaces do not require a shared clock. Both ports can run up to 66 MHz, while the PI7C8150B-33 family option is limited to 33 MHz. These characteristics distinguish the bridge from simpler endpoint devices: the PI7C8150BB family translates bus transactions between two PCI segments rather than terminating only one host bus. Its large 208-pin package also provides the substantial I/O and power connections required by two full 32-bit PCI interfaces.
Mechanically, the MAE ordering code is associated with the 208-FQFP 28 mm by 28 mm package. The package is substantially larger than a modern low-pin-count interface IC, so its footprint imposes demanding PCB routing and assembly requirements. Exact pin names, exposed-pad connections, voltage tolerances, input thresholds, output timing, current limits, temperature ratings, and package thermal data were not included in the supplied verified records and must therefore be confirmed in the manufacturer datasheet before schematic capture or layout release.
Typical applications include PCI-to-PCI expansion systems, embedded industrial control platforms, communications equipment, legacy data-acquisition chassis, and computer expansion products that require an additional bus segment. The asynchronous capability can simplify clock-domain planning when the two PCI segments do not operate in lockstep. However, system designers must still validate bus timing, termination, drive strength, isolation requirements, and power sequencing against the specific board configuration.
The main design consideration is PCB complexity. Two full 32-bit PCI buses require careful point-to-point routing for address, data, control, interrupt, and clock signals, together with conservative return-path planning. Layout should minimize stubs, provide continuous reference planes, control crosstalk, and keep bypass connections close to the device. Because the verified data does not supply complete pinout or layout guidance, engineers should use the official Diodes PI7C8150B documentation rather than infer connections from third-party listings.
This page consolidates the verified manufacturer description, distributor identification, package information, and product-family behavior into an engineer-oriented reference. It also distinguishes documented capabilities from missing electrical data and explains when a true pin-compatible replacement cannot be confirmed from the available cross-reference records.

Applications typiques
PI7C8150BMAE convient pour 6 applications: PCI Expansion Systems, Industrial PCI Control Platforms, Data-Acquisition Chassis, Communications Equipment, Embedded Computer Backplanes, Legacy PCI Adapter Products.
PCI Expansion Systems
The PI7C8150BMAE fits legacy PCI expansion systems that need a second bus segment rather than a conventional endpoint device. Its two 32-bit interfaces can connect a primary PCI bus to a secondary bus, supporting transaction transfer while retaining operation up to 66 MHz. The Diodes product page confirms asynchronous operation and PCI Revision 2.2 compliance, making the device relevant where the two segments do not share identical clocking. The principal engineering trade-off is PCB density: two full 32-bit interfaces require a large 208-FQFP footprint and careful routing of address, data, command, interrupt, and clock signals. The available verified records do not provide complete timing or signal-integrity limits, so implementation must follow the official datasheet and PCI system-design guidance.

Industrial PCI Control Platforms
PI7C8150BMAE can support industrial controllers that separate a host PCI segment from an acquisition or peripheral bus. The two 32-bit ports and asynchronous operation provide architectural flexibility when the primary and secondary buses are not clocked together. Its documented 66 MHz capability suits legacy industrial PCI infrastructure, while the 3 V to 3.6 V supply range identifies the device as a modern 3.3 V interface component. Deployment in an industrial enclosure requires additional verification of operating temperature, isolation, emissions, and long-term availability because those details were not present in the supplied records. Board-level reliability also depends on controlled-impedance routing and adequate power-plane distribution around the 208-pin package.
Recommandé
Data-Acquisition Chassis
The PI7C8150BMAE is applicable to data-acquisition chassis that need to bridge a host PCI segment to a secondary card cage or peripheral bus. A full 32-bit primary interface and 32-bit secondary interface preserve the PCI Local Bus Specification Revision 2.2 operating model while allowing the bus segments to operate asynchronously. The verified 66 MHz rating can shorten transaction latency compared with a 33 MHz bridge, but the benefit is realized only when the complete signal path supports that rate. Designers should evaluate connector loss, clock jitter, trace length, loading, and termination before enabling 66 MHz operation. Because detailed setup timing, hold timing, and electrical thresholds were not supplied, the official Diodes documentation remains the controlling source.
Recommandé
Communications Equipment
PI7C8150BMAE can isolate or extend PCI connectivity in communications equipment that includes multiple legacy bus segments. Its asynchronous bridge operation allows the primary and secondary PCI interfaces to function without a common clock, while the 32-bit datapaths support the bandwidth expected from PCI Revision 2.2 designs. For telecommunications or network-processing equipment, this can help partition traffic between host and peripheral card sections. Engineering attention is required around power integrity and signal integrity because the package exposes two complete high-speed parallel interfaces. The available verified records do not identify I/O voltage tolerances, per-pin current limits, or isolation capability, so those specifications must be checked before using the bridge in safety-critical or line-card applications.
Recommandé
Embedded Computer Backplanes
The PI7C8150BMAE is suited to embedded backplanes that need a transparent PCI-to-PCI link between a host processor and an expansion interface. Two 32-bit ports provide a direct bridge topology, and asynchronous operation can reduce constraints caused by mismatched bus clocks. The 208-FQFP package offers the pin count associated with full primary and secondary interfaces but requires a substantial controlled-impedance PCB. Backplane designers should minimize layer transitions, provide uninterrupted reference planes, account for connector and via capacitance, and keep clock traces well controlled. The verified manufacturer description establishes the bridge's PCI Revision 2.2 and 66 MHz capabilities, while exact AC timing, drive strength, and termination guidance must be obtained from the full manufacturer datasheet.
Recommandé
Legacy PCI Adapter Products
PI7C8150BMAE can be used in legacy PCI adapter products that need to present a secondary PCI bus to an external enclosure or downstream board. Its two 32-bit ports and support for frequencies up to 66 MHz align with conventional PCI Revision 2.2 expansion hardware. Asynchronous operation offers additional flexibility when the adapter's primary interface and downstream bus are not synchronized. The device should not be selected merely by its advertised PCI function; the adapter designer must also verify voltage levels, termination requirements, reset behavior, clock topology, and connector fanout from the official datasheet. Because the package is a 208-pin 28 mm square FQFP, assembly planning must include suitable board area, fine-pitch inspection, and thermal-evacuation assumptions.

Notes de conception
Treat both PCI interfaces as controlled-impedance point-to-point channels. Maintain uninterrupted reference planes beneath address, data, control, interrupt, and clock routes; minimize stubs and layer transitions; and match trace geometry to the impedance required by the complete board stack-up. The verified records do not provide a recommended stack-up, impedance value, via count, or length-matching rule, so these details must come from the official Diodes PI7C8150B documentation and the overall PCI platform specification. Avoid substituting generic Ethernet routing guidance for this parallel PCI bridge.
Estimated: the device's 3 V to 3.6 V core-supply range is verified, but core current and I/O current are not. Before assigning the power budget, obtain worst-case and typical current from the manufacturer datasheet and include every supply rail. Estimated: total dissipated power equals the sum of each rail voltage multiplied by its current, while junction-temperature rise equals total dissipated power multiplied by the applicable thermal resistance. Validate the result against the actual PCB copper, airflow, ambient temperature, and neighboring heat sources rather than relying only on the package rating.
Do not assume that a 66 MHz device rating guarantees 66 MHz operation in every chassis. Clock jitter, connector and via capacitance, trace length, loading, request and arbitration behavior, and adjacent high-speed signals can all reduce margin. Use the manufacturer's setup and hold timing, output drive, input-threshold, and loading information to establish the operating envelope. If the system cannot meet those constraints, the PI7C8150B-33 family option may be a lower-speed engineering choice, but it requires a separate 33 MHz timing and signal-integrity review.
Do not substitute the MAE ordering code solely from the base PI7C8150B family name. The verified comparison record identifies PI7C8150BMAIE as a related candidate but does not expose the suffix differences, temperature grade, or complete pin table. Procurement or engineering teams should compare the manufacturer's ordering information, package drawing, pin compatibility, voltage limits, and lifecycle status. Packaging suffixes such as tube or tray variants are orderable-format distinctions and should not be presented as separate electronic alternatives.
Informations de conformité
The supplied verified records do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed from the current manufacturer product documentation and the specific ordering code.
