PI7C8154BNAE - 64-Bit 66MHz PCI Bridge | Diodes Incorporated
Teilenummer: PI7C8154BNAE ✓ AktivPI7C8154BNAE Übersicht
A PCI-to-PCI bridge is a type of interface controller that connects two PCI bus domains electrically and logically. It belongs to the PCI interface controller hierarchy, where bus controllers and bridges coordinate address decoding, transaction forwarding, arbitration, and compatibility between peripheral buses and host systems. The PI7C8154BNAE supports the 64-bit, 66MHz implementation described by the PCI Local Bus Specification, Revision 2.2.
Key characteristics include asynchronous two-port operation, a 64-bit parallel PCI data path, and a maximum operating frequency of 66MHz. The device is intended for 3.3V operation, with an industrial operating-temperature range of 0°C to 85°C. Its 304-PBGA construction provides a large, mechanically robust package for systems requiring hundreds of high-speed PCI connections.
Technically, the bridge provides the interface between two independently operating PCI bus segments. Its asynchronous architecture allows transactions to be transferred between buses with different timing characteristics, while maintaining the full 64-bit width and 66MHz operating rate of the target PCI implementation. Correct PCB implementation therefore depends on careful power distribution, controlled-impedance routing, and complete decoupling around this high-pin-count device.
Typical applications include industrial PCI systems, embedded server and storage platforms, industrial networking equipment, test systems, and legacy PCI expansion platforms that require an additional bus segment. The device can also support compatibility and bridging designs in industrial control, data-acquisition, communications, and specialized embedded equipment.
Designers should pay particular attention to the 304-ball land pattern, power and ground-plane assignment, high-speed signal integrity, and the PCI routing rules in the manufacturer datasheet. Because this is a large BGA device with many connections, assembly inspection and via-in-pad or via-under-bump design practices may materially affect manufacturing yield and long-term reliability.
This product page combines interface categorization, verified operating characteristics, alternative-device guidance, and practical PCB considerations to help engineers evaluate the PI7C8154BNAE for legacy PCI bridging applications.

Typische Anwendungen
PI7C8154BNAE ist geeignet für 6 Anwendungs: Industrial PCI Control Systems, Embedded Server and Storage Expansion, Industrial Networking Equipment, PCI Data-Acquisition Systems, Legacy PCI Test and Measurement, Embedded Communications Equipment.
Industrial PCI Control Systems
The PI7C8154BNAE fits industrial PCI control systems that need to extend a legacy bus to a second asynchronous PCI segment. Its 64-bit data width preserves the full transfer capability of the PCI implementation, while the 66MHz operating frequency supports the documented PCI Local Bus Specification Revision 2.2 implementation. Use the bridge between a host bus and a populated peripheral segment, with both sides operating within the permitted PCI loading and timing topology. The 3.3V supply and 0°C to 85°C operating range suit controlled industrial enclosures, although final thermal qualification remains system dependent. PCB implementation should preserve uninterrupted ground planes, adequate supply distribution, and the high-speed topology required for 66MHz operation.
Empfohlen
Embedded Server and Storage Expansion
The PI7C8154BNAE is suitable for embedded server and storage platforms that retain a 64-bit PCI expansion segment. Two asynchronous ports allow the bridge to connect host and peripheral bus domains while preserving 64-bit transfers and operation up to 66MHz. In this topology, the bridge is a transaction-routing element rather than a storage controller, so it works alongside the host, storage interface, clocking, and power components. Its 304-PBGA package lowers interconnect escape complexity compared with a large perimeter-lead device, but it requires careful BGA assembly planning. Confirm connector, termination, clock-reference, and isolation requirements from the manufacturer design documentation before placing the component in a new storage platform.
Empfohlen
Industrial Networking Equipment
The PI7C8154BNAE can support legacy PCI expansion inside industrial networking equipment where a 64-bit, 66MHz bus connects specialized communication, DSP, or data-acquisition modules. The asynchronous two-port arrangement helps divide the system into separate PCI bus segments, reducing the loading presented to one segment when the topology is designed correctly. The device’s 3.3V operating requirement and 0°C to 85°C range align with many temperature-controlled network appliances, but enclosure temperature and airflow must be checked at worst case. Preserve the specified reference-clock arrangement, maintain continuous power and ground planes, and follow the manufacturer’s PCI routing guidance to avoid timing degradation at 66MHz.
Empfohlen
PCI Data-Acquisition Systems
The PI7C8154BNAE can bridge a PCI data-acquisition subsystem to a second asynchronous PCI segment when the acquisition platform uses a 64-bit legacy PCI architecture. The 66MHz capability and full 64-bit width support the documented PCI implementation, allowing multiple compatible acquisition peripherals to remain on an isolated bus segment. The bridge does not perform analog measurement or buffering; it provides the PCI transaction path between system segments. Engineers should account for clock distribution, bus arbitration, connector loading, and power sequencing in the complete chassis. Because acquisition cards can add substantial bus loading, reproduce the reference topology and validate timing at the intended population and card length rather than relying only on nominal clock-rate ratings.
Empfohlen
Legacy PCI Test and Measurement
The PI7C8154BNAE is appropriate for test and measurement chassis that need to connect legacy 64-bit PCI instruments, interface cards, or processor modules through a second PCI bus domain. Its 66MHz asynchronous operation enables the bridge to accommodate differing bus timing domains while maintaining the documented PCI transaction width. This can simplify the migration path for laboratory equipment that still depends on PCI peripheral cards. The device should be placed where power and ground planes remain continuous and where high-speed traces can be routed without unnecessary stubs. Validate connector pin assignments, termination, arbitration behavior, and the complete bus topology using the manufacturer reference design and PCI system specification.
Empfohlen
Embedded Communications Equipment
The PI7C8154BNAE can serve embedded communications equipment that retains PCI-based radio, modem, or protocol-processing modules. The two-port asynchronous bridge supports segmented bus arrangements, while 64-bit width and 66MHz operation preserve the performance level defined for the PCI Local Bus Specification Revision 2.2 implementation. Such equipment typically demands deterministic bus behavior, controlled power delivery, and repeatable BGA assembly, making the manufacturer layout and test guidance important during design. Use the 304-PBGA land pattern exactly and avoid placing disruptive split planes beneath the device. Confirm signal and power tolerances, clock distribution, thermal performance, and peripheral-card loading before production release.

- Large 304-PBGA package supports dense PCI connectivity (vs. PCI2060IGHK)
Designhinweise
Implement the 304-PBGA footprint directly from the manufacturer land-pattern drawing and preserve continuous ground planes beneath the device. The large ball count requires coordinated escape routing, so fan out supply, ground, clock, and high-speed signals in a controlled sequence rather than routing them independently. Validate the complete stackup and impedance before fabrication and inspect solder joints using a process capable of evaluating the dense BGA geometry.
Route all 66MHz PCI signals as a controlled-impedance bus using the stackup and topology specified by the manufacturer. Avoid stubs, unnecessary test pads, and right-angle transitions on high-speed paths. Match clock distribution to the documented reference configuration and account for connector and card loading. System-level timing validation should include the intended peripheral population because board loading and topology can affect operation even when the component itself is rated for 66MHz.
Provide a low-impedance 3.3V distribution network with local bulk and high-frequency decoupling placed close to the corresponding BGA power balls. Keep plane transitions symmetric and minimize sharing of high-current return paths between power and signal distributions. Decoupling values and stability requirements should follow the manufacturer guidance, and the power system should be tested for adequate margin under maximum bus-loading and peripheral-card activity.
Compliance-Informationen
No explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations were identified. AEC-Q100 is not applicable because the PI7C8154BNAE is an industrial-temperature PCI bridge rather than an automotive-qualified device.
