PI7C8154BNAIE - 64-Bit 66MHz PCI Bridge | Diodes Incorporated
Артикул: PI7C8154BNAIE ✗ Снят с производстваPI7C8154BNAIE Обзор
A PCI-to-PCI bridge is an interface IC within the PCI interface hierarchy and broader computer-interface semiconductor category. It allows a host system or embedded PCI platform to extend its available PCI bus resources by connecting two PCI segments. The bridge coordinates transaction forwarding, arbitration, and bus ownership across the two segments while presenting a unified PCI interface to connected peripherals.
The PI7C8154BNAIE is specified as a 2-port, 64-bit, 66 MHz asynchronous PCI bridge. Its 304-PBGA package provides the large number of signal and power connections required for parallel PCI data, address, command, and control paths. The package is surface-mount technology and uses a 31 x 31 mm body according to the product listing. The device is intended for industrial, embedded, and legacy PCI platform designs requiring a dedicated bus-to-bus bridge rather than a general-purpose serial interface controller.
The PI7C8154B family was designed for compatibility with the 64-bit, 66 MHz PCI Local Bus Specification Revision 2.2. Because the target is an older parallel-bus bridge, system-level validation is important. The host firmware, PCI configuration space, interrupt routing, clocking, termination, and power-delivery arrangement must be checked against the board design and the manufacturer datasheet before deployment.
Typical uses include PCI industrial controllers, embedded computer backplanes, PCI expansion chassis, data-acquisition systems, and legacy embedded platforms that need two PCI bus segments. In these systems, the bridge allows an existing PCI host to reach additional cards without replacing the host processor or redesigning the entire bus topology.
Layout is the primary implementation consideration. Route high-speed parallel PCI signals with controlled impedance, continuous reference planes, and minimal stubs. Follow the manufacturer pin-assignment and escape-routing guidance for the 304-PBGA footprint, and place decoupling and termination components close to their associated pins. This page combines the manufacturer-family specifications, package details, sourcing facts, and practical integration considerations for engineers evaluating the PI7C8154BNAIE.

Типичное применение
PI7C8154BNAIE подходит для 6 применениеs: Embedded PCI Controller Expansion, Industrial Data-Acquisition System, PCI Backplane and Expansion Chassis, Legacy PCI Network and Communication Adapter, PCI Test and Measurement Platform, PCI-to-PCI Bus Isolation in Embedded Equipment.
Embedded PCI Controller Expansion
The PI7C8154BNAIE fits embedded platforms that use one PCI host bus and need access to a second PCI segment. Its two-port asynchronous bridge architecture separates the bus domains while supporting 64-bit transfers at up to 66 MHz. This allows an industrial controller to extend its PCI resource set without replacing the host processor. Integration remains demanding because the 304-PBGA package requires careful ball escape routing, plane continuity, clock distribution, decoupling, and validation of arbitration and interrupt behavior under the PCI Local Bus Specification Revision 2.2.
Industrial Data-Acquisition System
A PI7C8154BNAIE can connect separate PCI bus segments in an industrial data-acquisition system that combines legacy acquisition cards with newer processing hardware. The confirmed 64-bit, 66 MHz, two-port asynchronous operation is appropriate for a parallel PCI topology where deterministic bus segmentation is required. The bridge should be placed so each segment has a clear electrical boundary and its clock and arbitration domain. Validation should cover card enumeration, interrupt routing, bus ownership transfers, power sequencing, and sustained transfers between acquisition and processing nodes.
PCI Backplane and Expansion Chassis
The PI7C8154BNAIE is suited to PCI backplanes and expansion chassis that need a dedicated bridge between two bus segments. Its two asynchronous ports support a segmented architecture, while the 64-bit, 66 MHz capability matches the PCI Local Bus Specification Revision 2.2 operating profile described by the manufacturer. In a backplane, maintain continuous ground references and controlled impedance for all address and data routes. Keep repeaters, terminations, and peripheral components positioned according to the system timing budget, and verify hot-plug or isolation behavior only if the chassis specification requires it.
Legacy PCI Network and Communication Adapter
The PI7C8154BNAIE can be used in legacy communication systems that retain PCI adapters for networking, protocol conversion, or specialized I/O. The bridge provides a way to preserve an existing PCI ecosystem while separating resources into two bus domains. Its stated 66 MHz ceiling and 64-bit width support the high end of the original parallel PCI interface, but software must correctly enumerate resources behind the bridge. Firmware and operating-system configuration should define bridge windows, interrupt routing, and device ownership before the adapter is deployed in a production system.
PCI Test and Measurement Platform
The PI7C8154BNAIE can support test and measurement equipment that separates PCI instrumentation from a host computer while retaining the legacy PCI card ecosystem. A segmented bridge arrangement allows dedicated analyzer, generator, or interface cards to operate behind the bridge without loading every device onto one electrical bus. Because the IC is a 304-PBGA component, the practical benefit depends on careful fanout and reference-plane design. Bring-up should include signal-integrity checks, enumeration across both ports, sustained transfer tests, fault injection, and confirmation that test-system timing margin remains acceptable.
PCI-to-PCI Bus Isolation in Embedded Equipment
The PI7C8154BNAIE fits embedded equipment that needs separate PCI bus segments for resource organization, electrical isolation, or controlled attachment of specialized cards. Its two asynchronous ports provide the basic segmentation function, and the 64-bit, 66 MHz specification matches the intended Revision 2.2 PCI environment. The implementation must preserve signal integrity on both sides of the bridge. Use short clock routes, maintain uninterrupted reference planes, decouple each supply domain at the device, and verify that arbitration and interrupt ownership remain correct when cards are added, removed, or bus-mastered.

Заметки по проектированию
Treat the 304-PBGA as a high-pin-count escape-routing problem. Follow the manufacturer ball map and recommended package-outline data, preserve continuous ground references beneath routed buses, and avoid layer transitions that create impedance discontinuities. Keep the PCI address, data, and control escape paths as short as practical. Validate the complete stack-up with the board fabricator and confirm that exposed-pad, via-in-pad, and thermal-relief requirements match the selected assembly process.
The 64-bit, 66 MHz PCI interface requires controlled-impedance routing and careful clock distribution. Match length where the platform design requires it, maintain uniform reference-plane continuity, and avoid stubs or test-point structures that create unnecessary reflections. Decoupling must be distributed near the relevant supply balls rather than grouped away from the device. Perform receiver-eye, timing-margin, and simultaneous-switching-noise checks under the expected card-loading and clock-jitter conditions.
Do not approve a substitute from package appearance alone. PI7C8154BNAE and PI7C8154ANAE are documented family candidates, while the -80 suffix changes a principal parameter designation. Confirm electrical limits, timing, configuration behavior, ordering information, and production status for the exact replacement. Firmware must also enumerate the bridge and resource windows correctly, and system validation should confirm arbitration, interrupt routing, and ownership transfer across both asynchronous PCI ports.
