PI7C8150BNDE - 32-Bit 66MHz PCI Bridge | Diodes Incorporated
MPN: PI7C8150BNDE ✗ Son Kullanım ZamanıPI7C8150BNDE Genel Bakış
A PCI-to-PCI bridge is an interface IC that connects two peripheral component interconnect buses and allows devices on one bus to communicate with resources on the other. In the interface hierarchy, the PI7C8150BNDE belongs to the PCI interface controller and bus-bridge category, where it provides protocol translation, transaction handling, and bus arbitration between conventional PCI domains. It is intended for established PCI systems rather than modern PCI Express designs.
The PI7C8150B family provides 32-bit primary and secondary ports that run as fast as 66 MHz. Both bus interfaces support asynchronous operation, which allows the bridge to operate between systems whose bus timing is not synchronized. The PI7C8150B-33 member is distinguished by a maximum 33 MHz operating frequency, while the PI7C8150B family described by the manufacturer supports operation up to 66 MHz.
As a PCI Local Bus Specification Revision 2.2 device, the bridge targets legacy parallel PCI infrastructure, including systems that require a secondary PCI bus behind a host bridge. Its 256-pin PBGA construction provides the dense pin access needed for two 32-bit PCI interfaces, associated control signals, clock inputs, power rails, and ground connections. The package is identified by distributors as a 17 mm by 17 mm 256-ball PBGA.
Typical uses include industrial PCI adapter designs, embedded legacy PCI systems, industrial control equipment, data-acquisition systems, and PCI expansion chassis that require a bridge between primary and secondary buses. The asynchronous operating capability is particularly relevant when the connected PCI domains do not share identical clock timing. Designers must also account for the physical size, routing density, and power requirements of a 256-pin BGA package.
The primary design consideration is that PI7C8150BNDE must be evaluated as a conventional PCI bridge rather than a PCI Express device. Board design requires exact BGA layout, controlled-impedance routing, adequate power-plane integrity, and compliance with the PCI Local Bus Specification Revision 2.2. Firmware and system configuration must also support the bridge and its bus-routing requirements.
This page consolidates the verified manufacturer and distributor information for the PI7C8150BNDE, distinguishes the 66 MHz part from the 33 MHz PI7C8150B-33 option, and identifies same-family replacement candidates. Detailed electrical values, pricing, pin assignments, and lifecycle details remain explicitly marked where the supplied source data does not provide verified values.

Tipik Uygulamalar
PI7C8150BNDE için uygundur 6 uygulamas: Industrial PCI Expansion Systems, Legacy PCI Data Acquisition, Embedded Legacy PCI Control, PCI Networking Adapters, Test and Measurement Systems, Storage and Communications Expansion.
Industrial PCI Expansion Systems
The PI7C8150BNDE is suitable for an industrial PCI expansion architecture that connects a primary PCI bus to a secondary bus through a dedicated bridge. Its two 32-bit ports support operation up to 66 MHz, while asynchronous operation accommodates buses that do not share identical timing. The device also targets PCI Local Bus Specification Revision 2.2 compatibility. The 256-pin PBGA requires careful power-plane and escape-routing design, but it provides the pin density needed for a full 32-bit bridge in a single package.
Önerilen
Legacy PCI Data Acquisition
The PI7C8150BNDE can bridge legacy PCI data-acquisition equipment to a host PCI domain. Its 32-bit primary and secondary ports operate up to 66 MHz, providing more bandwidth than the 33 MHz PI7C8150B-33 family member. Asynchronous operation is useful when the acquisition subsystem and host bridge use different clock arrangements. System designers should verify acquisition-card timing, arbitration behavior, and PCI Revision 2.2 electrical requirements against the complete manufacturer datasheet.
Önerilen
Embedded Legacy PCI Control
The PI7C8150BNDE fits embedded control systems that retain conventional PCI peripherals but use a local processor or FPGA as the upstream controller. Two 32-bit asynchronous PCI ports allow compatible primary and secondary bus segments to operate up to 66 MHz. This arrangement can isolate slower peripherals from the main processing domain while retaining PCI Revision 2.2 compatibility. Clock topology, reset requirements, interrupt routing, and the 256-ball PCB footprint remain critical implementation considerations.
Önerilen
PCI Networking Adapters
A networking adapter can use the PI7C8150BNDE to join a PCI host environment to a secondary bus containing communication equipment. The bridge's two 32-bit ports and 66 MHz maximum operation provide a conventional PCI path for Ethernet, serial, or industrial-network controllers. The asynchronous interface permits separate clock domains, although power sequencing and termination still need validation. Use the bridge for legacy PCI attachments rather than attempting to connect PCI Express modules to a parallel PCI bus.
Önerilen
Test and Measurement Systems
The PI7C8150BNDE can be evaluated for legacy test and measurement platforms that need a secondary PCI bus behind a host controller. The two 32-bit ports run up to 66 MHz and support asynchronous operation, making the bridge relevant to instrument systems with independently timed PCI segments. Its 256-pin PBGA package demands advanced PCB assembly capability and careful return-path design. Confirm sustained bus loading, interrupt latency, and instrument-specific timing against the complete datasheet before production use.
Önerilen
Storage and Communications Expansion
The PI7C8150BNDE supports legacy expansion systems that connect storage or communications adapters to a host PCI bus through a secondary segment. Both interfaces are 32 bits wide and can operate at 66 MHz, supporting sustained legacy PCI transactions while asynchronous operation helps bridge different clock domains. The design must observe PCI bus arbitration, termination, and power requirements. Because the part is a conventional PCI bridge, it should not be treated as a PCI Express-to-PCI protocol translator.

Tasarım Notları
The PI7C8150BNDE uses a 256-pin PBGA measuring 17 mm by 17 mm, so the board must provide the exact manufacturer land pattern rather than a generic BGA footprint. Route both 32-bit PCI buses with continuous reference planes, minimize layer transitions, and provide low-inductance connections from the BGA power balls to the relevant power planes. Confirm paste volume, pad geometry, assembly profile, and X-ray inspection requirements with the PCB and assembly suppliers.
Maintain controlled-impedance routing for the 32-bit primary and secondary PCI interfaces and avoid splitting reference planes beneath the BGA. The verified data establishes operation up to 66 MHz, but it does not provide rise-time, AC timing, or board-derating values. Use the complete datasheet and PCI Local Bus Specification Revision 2.2 to determine trace geometry, termination, loading, and via transitions.
Decouple each documented power rail directly beneath or close to the corresponding 256-ball positions, using the capacitance and voltage values specified in the complete manufacturer datasheet. Keep the high-frequency return path continuous through the BGA region and avoid routing noisy external power converters near the bridge. The verified excerpts provide only the 3.6 V maximum supply value, so current limits, rail sequencing, and startup behavior must not be guessed.
Do not treat PI7C8150BNDE as a PCI Express controller or substitute the 33 MHz PI7C8150B-33 into a design that requires the full 66 MHz bridge. Also do not infer pin compatibility from the 256-pin package name alone. Confirm clock, reset, interrupt, power, and every exposed-ball connection against the official pinout, and verify the complete PCI system configuration before production release.
