PI7C8150AND-33 - 2-Port 33MHz PCI Bridge | Diodes
MPN： PI7C8150AND-33 ✓ 啟用中PI7C8150AND-33 概覽
A PCI-to-PCI bridge is an interface integrated circuit used to extend and isolate conventional Peripheral Component Interconnect bus segments. It belongs to the PCI interface controller class, the interface IC hierarchy, and the broader semiconductor category. Its primary function is to translate and coordinate bus transactions so that devices on separate PCI segments can communicate while each segment operates as an independent bus.
The PI7C8150AND-33 provides two PCI ports, a 33 MHz operating frequency, and a 256-pin PBGA package. Its 17 x 17 mm ball-grid-array construction supports dense board layouts where fine interconnect pitch and many power, ground, and signal connections are required. Current ratings, voltage limits, electrical timing, host interfaces, and supported PCI signaling modes should be confirmed in the manufacturer datasheet before schematic or layout release.
This bridge architecture is useful in embedded industrial controllers, legacy PCI expansion systems, test equipment, communication appliances, and embedded computing platforms that still depend on conventional PCI topology. The two-port organization allows a motherboard or mezzanine design to divide devices across multiple bus segments instead of placing every device on one shared PCI bus.
The principal engineering trade-off is board complexity. A 256-pin PBGA requires careful escape routing, multilayer construction, ball assignment review, and assembly-process control. Power delivery and return paths must also support the bridge's switching and I/O requirements while minimizing crosstalk on high-fanout bus signals.
Use the manufacturer pin-description table to assign every power, ground, clock, reset, interrupt, and PCI data contact. Confirm the complete board stack-up, ball-map orientation, decoupling strategy, and manufacturing rules before release because the public product summary does not provide a complete production pin list.
This page organizes the verified device identity, package information, sourcing path, family relationship, and practical integration considerations into a concise engineering reference. It also highlights the distinction between the ordered -33 configuration and related PI7C8150 family members without substituting unverified performance claims.

典型應用
PI7C8150AND-33 適用於 6 應用s: Embedded Industrial PCI Controller, PCI Test and Measurement Fixture, Legacy PCI Expansion Backplane, Communication Equipment Interface, Data Acquisition Control Platform, PCI Security and Storage Appliance.
Embedded Industrial PCI Controller
The PI7C8150AND-33 fits an embedded industrial controller that needs two conventional PCI bus ports operating at 33 MHz. Placing compatible PCI devices behind the bridge can separate traffic into dedicated segments and reduce contention compared with placing every peripheral on one shared bus. The 256-pin PBGA provides the required signal and power connections, but it also demands multilayer escape routing, strict impedance control, and assembly validation. Before schematic release, verify the complete host-interface requirements, PCI signal termination, supply rails, timing, and operating-temperature limits against the manufacturer datasheet.
推薦
PCI Test and Measurement Fixture
A PCI test fixture can use the PI7C8150AND-33 to bridge a host system and a second conventional PCI segment populated with acquisition, interface, or diagnostic cards. Its identified 33 MHz operating rate and two-port organization fit legacy PCI equipment where bus segmentation improves device organization. The bridge does not eliminate the need for careful signal-integrity design: the 256-pin PBGA must be placed on a controlled multilayer board, with high-fanout nets routed away from sensitive analog sections. Confirm the fixture's voltage, timing, reset, and termination requirements before releasing the schematic.
推薦
Legacy PCI Expansion Backplane
The PI7C8150AND-33 is suitable for a legacy PCI expansion backplane where two bus segments must communicate through a dedicated bridge controller. The 33 MHz PCI operating point and two-port arrangement support systems that retain conventional PCI peripherals while organizing traffic across separate segments. Backplane implementation requires careful attention to length matching, layer transitions, ground continuity, and connector-to-bridge placement. Because the device uses a 256-pin PBGA rather than a through-hole package, the board also needs solder-mask and paste controls appropriate for its ball pitch and an assembly process qualified for that package.
推薦
Communication Equipment Interface
Network and communication appliances that retain conventional PCI add-in cards can use the PI7C8150AND-33 as a two-port PCI interface bridge. Its identified 33 MHz operation allows a system architect to isolate a management, storage, or acceleration card behind a separate PCI segment while preserving access through the host bridge. The design must account for the 256-pin PBGA's thermal and routing requirements, especially when several high-speed peripherals share power distribution paths. Validate electrical timing, reference clocks, reset behavior, interrupt routing, and all termination details in the manufacturer documentation before layout.
推薦
Data Acquisition Control Platform
A data-acquisition platform can use the PI7C8150AND-33 to connect a controller to a second PCI domain containing I/O, processing, or communication cards. The two-port topology helps separate acquisition peripherals from the main system bus, while the 33 MHz operating rate matches conventional PCI traffic. Because acquisition systems may combine digital, analog-adjacent, and high-fanout digital circuitry, the bridge's power and ground connections require a quiet distribution network and the PCI nets require controlled impedance. Confirm signal integrity, grounding, clocking, and thermal requirements against the complete system specification.
推薦
PCI Security and Storage Appliance
Security appliances and storage controllers can employ the PI7C8150AND-33 when they need two conventional PCI domains and a 33 MHz bridge operating point. A dedicated bridge segment can organize storage, security-processing, or network-interface adapters while preserving a controlled relationship to the host PCI bus. The PBGA implementation is appropriate for a dense multilayer platform, but designers must reserve adequate copper for power delivery and ground return and maintain controlled impedance on clock and data nets. Confirm address-map behavior, reset requirements, interrupt topology, timing margins, and production status before committing the platform architecture.

- High-density board integration (對比PI7C8150AND)
設計說明
Treat the 256-pin PBGA as a high-density routing and assembly interface. Assign every ball from the manufacturer pin-description table, preserve the package orientation, and provide multilayer escape routing without vias where practical. Validate solder-mask-to-pad and paste-to-pad conditions against the package drawing and the board manufacturer's assembly capability before releasing artwork.
Route clock, reset, interrupt, and PCI data nets with a controlled-impedance stack-up and continuous reference planes. Keep the bridge's bypass connections close to their associated power balls and provide a low-impedance ground path beneath and around the device. Review trace spacing, via stubs, and layer transitions against the PCI timing and topology requirements in the manufacturer datasheet.
Do not treat a similar PI7C8150 order code as interchangeable until the exact ball map, voltage ratings, timing, reset behavior, and production configuration have been checked. A shared package outline does not guarantee identical signal assignments. Record the approved manufacturer ordering code and verify it against the assembled-board inspection plan to prevent an incorrect bridge from entering production.
合規資訊
The available product information identifies the device, interface function, operating frequency, package, and pin count but does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The AEC-Q100 field is not applicable because this is a conventional PCI interface bridge rather than an automotive-qualified device.
