PI7C8148ANJE - 2-Port 32-Bit 66MHz PCI Bridge | Diodes
部品番号: PI7C8148ANJE ✗ 生産終了PI7C8148ANJE 概要
A PCI bridge is an interface integrated circuit that connects two PCI bus segments and allows devices on one segment to communicate with devices on another. In the PCI hierarchy, the PI7C8148ANJE sits between a host or upstream PCI bus and a downstream PCI segment. Its 32-bit, 66 MHz capability makes it relevant to legacy PCI expansion, embedded system integration, industrial control, and legacy industrial computing platforms where a single bus cannot directly reach all peripherals.
The main verified device characteristics are the 2-port PCI-to-PCI architecture, 32-bit PCI data width, 66 MHz operating frequency, 3 V to 3.6 V supply range, and 160-LFBGA (15 x 15 mm) package. These specifications define the electrical and mechanical envelope for the component. The package uses surface-mount LFBGA construction, requiring a PCB land pattern with controlled escape routing and careful via placement beneath the device.
The bridge is intended to provide transparent PCI bus segmentation where upstream and downstream agents must share a PCI bus. Using a bridge allows more physical distance between bus loads than a single shared segment may support, while preserving protocol handling within the PCI interface domain. Designers should confirm arbitration, interrupt routing, clocking, and downstream-bus loading against the manufacturer datasheet before finalizing a system.
Typical uses include legacy PCI industrial controllers, PCI-to-PCI embedded adapters, test equipment, communication systems, and expansion systems that must retain a 32-bit 66 MHz PCI interface. The 160-LFBGA package is most appropriate for multilayer PCB designs where fine-pitch routing and adequate ground-plane continuity can be implemented.
The main design consideration is package complexity. A 160-LFBGA footprint is more demanding than a leaded package for assembly, inspection, and repair, so designers should provide adequate via-in-pad or via fanout options, a continuous reference plane, and process controls for solder bridging. The 3 V to 3.6 V supply requirement also means the bridge must be integrated with a compatible 3.3 V power rail and correctly decoupled at its supply pins.
This page consolidates the verified distributor and manufacturer-linked information for PI7C8148ANJE, provides practical packaging and PCB guidance, and distinguishes confirmed parameters from information that must be confirmed in the manufacturer datasheet before production release.

主な用途
PI7C8148ANJE の用途: 6 件s: Legacy PCI Industrial Controllers, PCI Expansion Systems, Industrial Test and Measurement Equipment, Embedded Communications Platforms, Legacy Storage Adapter Systems, Medical and Diagnostic Equipment Platforms.
Legacy PCI Industrial Controllers
The PI7C8148ANJE fits legacy industrial controller architectures that require an additional 32-bit PCI bus segment operating at up to 66 MHz. It can bridge an upstream PCI host or system bus to a downstream agent such as an I/O controller, storage interface, or communication card. The verified 3 V to 3.6 V supply range integrates with a conventional 3.3 V rail. Because this is a 160-LFBGA device, the motherboard must provide a high-density land pattern, short escape routes, and uninterrupted power and ground planes. Board partitioning, isolation, arbitration, and interrupt behavior must follow the complete manufacturer timing and layout requirements.
おすすめ
PCI Expansion Systems
PI7C8148ANJE is appropriate for expanding a legacy PCI platform with another 32-bit, 66 MHz PCI segment. It can separate two PCI bus groups while maintaining the parallel PCI interface expected by the target system. The verified 160-LFBGA (15 x 15 mm) package supports compact multilayer boards, but assembly and repair require careful BGA process control. System architects should verify downstream bus loading, arbitration windows, reset behavior, and electrical timing against the manufacturer datasheet before using the bridge as the sole segmentation element.
おすすめ
Industrial Test and Measurement Equipment
The PI7C8148ANJE can support legacy test and measurement instruments that retain one or more 32-bit PCI agent devices at up to 66 MHz. A bridge permits the instrument's main bus to communicate with a secondary measurement or I/O segment while preserving the PCI protocol hierarchy. Its confirmed 3 V to 3.6 V operating range is compatible with a 3.3 V instrument architecture. The 160-LFBGA footprint demands a multilayer PCB, calibrated decoupling, and inspection methods capable of detecting solder-joint defects. Environmental, temperature, and lifecycle limits are not available in the verified snippets and must be checked before deployment.
おすすめ
Embedded Communications Platforms
PI7C8148ANJE can bridge PCI segments in embedded communications equipment built around legacy 32-bit PCI agents. Its 66 MHz maximum PCI frequency provides a defined operating target for the upstream and downstream parallel buses, while the 2-port architecture identifies it specifically as a PCI-to-PCI device. A communications system can place the bridge near a distributed I/O or DSP-related PCI card group to improve physical bus organization. Designers should budget the 160-LFBGA assembly area and route high-speed PCI signals according to the manufacturer recommendations rather than generic BGA practice.
おすすめ
Legacy Storage Adapter Systems
The PI7C8148ANJE may be used when a legacy storage or storage-controller subsystem communicates through a 32-bit PCI segment at up to 66 MHz. The bridge creates a distinct downstream PCI segment for compatible disk controllers, RAID interfaces, or data-acquisition cards. The verified supply range of 3 V to 3.6 V is suitable for a 3.3 V platform, but power budget and regulator behavior remain to be confirmed from the datasheet. The 15 x 15 mm 160-LFBGA package also requires careful thermal distribution, via-in-pad consideration, and solder-joint inspection to support reliable industrial operation.
おすすめ
Medical and Diagnostic Equipment Platforms
PI7C8148ANJE can be evaluated for legacy medical or diagnostic equipment that depends on 32-bit 66 MHz PCI expansion cards. The bridge can isolate a secondary PCI agent group from the primary platform bus, allowing specialized acquisition or processing cards to communicate through the PCI hierarchy. However, the verified data does not establish medical certification, operating-temperature limits, reliability ratings, or long-term lifecycle status. Those requirements must therefore be resolved through current manufacturer documentation. Any medical use also requires system-level electrical safety, EMC, and risk-management validation independent of the component specifications.

設計ノート
Use the exact manufacturer land pattern for the 160-LFBGA package rather than deriving a footprint from the 15 x 15 mm body size alone. Confirm ball pitch, pad dimensions, solder-mask design, via-in-pad policy, and the number of PCB layers against the package drawing. Maintain continuous ground references beneath the device and route escape traces on the layer recommended by the manufacturer to reduce discontinuities and assembly defects.
The verified operating range is 3 V to 3.6 V, so design the PI7C8148ANJE from a stable 3.3 V rail. Place the required input and output decoupling capacitors directly at the associated supply and ground balls in accordance with the datasheet schematic. Do not estimate the rail's current capability or capacitor values from the snippets; obtain the manufacturer power data and recommended network before release.
Do not substitute a generic PCI bridge based only on the words “32-bit” and “66 MHz.” PCI-to-PCI devices can differ in pin assignment, arbitration, reset, interrupt, clocking, and downstream-bus loading behavior. Also do not treat the supplied Advance Information datasheet listing as proof of final production limits. Confirm the current revision, lifecycle status, grade, ordering code, and timing characteristics with the manufacturer.
Thermal analysis must use the actual dissipation, ambient temperature, board construction, and package thermal data from the manufacturer datasheet, none of which are present in the verified snippets. On a 160-LFBGA device, spreading heat through adjacent copper layers can be as important as exposed package area. Validate the assembled board with thermocouples or thermal imaging under worst-case traffic and environmental conditions.
コンプライアンス情報
The supplied verified snippets do not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed through current Diodes Incorporated documentation.
