MPN: PI7C8150DMAE ✗ End of LifePI7C8150DMAE Overview
A PCI-to-PCI bridge is a specialized interface semiconductor that translates and buffers transactions between two Peripheral Component Interconnect bus segments. It sits within the interface-IC and semiconductor hierarchy and can isolate traffic, improve bus fan-out, and support legacy PCI system architectures. The PI7C8150DMAE is particularly relevant to embedded industrial equipment, industrial control systems, legacy PCI expansion platforms, test equipment, and data-acquisition systems where a conventional PCI interface must be extended to another PCI segment.
The Diodes Incorporated product listing identifies the PI7C8150DMAE as a PCI-to-PCI bridge interface with two ports. Its 208-FQFP package supports the numerous signals required by a conventional PCI bridge, while its size and pin count make careful high-speed layout essential. The available product information also identifies Tube packaging, lead-free construction, and RoHS status for this part. Tube packaging is intended for automated pick-and-place and board assembly, but the exact tube quantity and shipping configuration should be confirmed before production planning.
The primary design consideration is signal integrity. Because the device bridges a parallel peripheral bus, routing must minimize trace-length mismatch, maintain continuous reference planes, provide proper termination, and avoid splits across PCB layers. Power and ground distribution also require careful treatment because multiple PCI signal groups and auxiliary functions can create simultaneous switching activity. A complete 208-pin symbol, pin names, and electrical limits cannot be reconstructed from the available product listings; use the manufacturer datasheet and its pin-description tables for layout and schematic work.
PI7C8150DMAE is most appropriate when maintaining an existing PCI topology matters more than adopting a modern serial interconnect. Its selection should be based on the host bus, target bus, clocking requirements, interrupt routing, and the exact electrical characteristics defined in the manufacturer documentation. This page combines package information, application guidance, replacement constraints, and practical layout considerations to support early design decisions without inventing unverified electrical values.

Typical Applications
PI7C8150DMAE is suitable for 6 applications: Industrial PCI Bus Expansion, Data-Acquisition Systems, Test and Measurement Instruments, Embedded Controller Platforms, PCI Storage and Memory Systems, Legacy PCI Networking Equipment.
Industrial PCI Bus Expansion
The PI7C8150DMAE fits embedded industrial platforms that need to divide a conventional PCI topology into two bridged bus segments. Its two-port PCI bridge architecture allows a host adapter and downstream PCI agent to communicate through a dedicated interface rather than loading the source bus with every transaction. The 208-FQFP package provides the pin count required for parallel PCI data, control, arbitration, interrupt, and auxiliary functions. Engineering attention is required for clock routing, impedance-controlled traces, reference-plane continuity, and termination because the parallel bus is sensitive to loading and trace-length mismatch.
Recommended
Data-Acquisition Systems
PI7C8150DMAE can support a data-acquisition instrument that retains a legacy PCI acquisition card while bridging it to another PCI segment. The two-port asynchronous arrangement is useful when separate bus domains are required for an instrument controller, memory-mapped I/O card, or downstream peripheral. The main design benefit is controlled PCI segmentation rather than direct multidrop loading. Signal-integrity review must cover bus length, point-to-point topology expectations, clock source distribution, termination, and the exact pin assignments of each optional function before the layout is released.
Recommended
Test and Measurement Instruments
The PI7C8150DMAE is suitable for a modular test instrument that uses PCI as an internal expansion mechanism. Two PCI-facing ports can isolate instrument subsystems and provide structured communication between a controller and acquisition or processing card. Its large 208-FQFP package requires adequate board area, but it supports the extensive conventional PCI signaling required by these systems. For reliable operation, keep synchronous PCI traces length-matched, preserve uninterrupted reference planes, provide clean power distribution, and validate the bridge's clock, reset, interrupt, and arbitration behavior as one subsystem.
Recommended
Embedded Controller Platforms
PI7C8150DMAE can be used in an embedded controller that needs to retain PCI compatibility with industrial modules or legacy expansion hardware. The two-port bridge provides a defined interface between controller and peripheral PCI segments, allowing system architecture to separate bus traffic while preserving the established PCI programming model. Designers should verify the bridge role, clocking behavior, reset sequence, and interrupt routing against the intended controller platform. The 208-FQFP package also demands component placement planning and adequate copper for the numerous power and ground connections.
Recommended
PCI Storage and Memory Systems
The PI7C8150DMAE can bridge a PCI storage or memory subsystem when a legacy controller must communicate with a downstream PCI agent. Segmentation helps organize traffic and provides a clearer interface between independently timed bus segments than a direct shared-bus arrangement. Because this is a parallel asynchronous bridge, the design must account for bus timing, clock distribution, termination, and the interaction of reset and interrupt signals. Confirm operating-current limits, voltage tolerances, and every auxiliary function from the official datasheet before selecting this IC for a new storage platform.
Recommended
Legacy PCI Networking Equipment
PI7C8150DMAE can support legacy PCI networking equipment that bridges an embedded PCI bus to another PCI-based processing or storage section. The asynchronous two-port interface may help isolate traffic within the subsystem, while preserving compatibility with conventional PCI cards and controllers. The implementation should include impedance-controlled routing, continuous ground references, careful clock topology, and power planes sized for the expected activity. Board validation should exercise hot-plug-related signals, serial EEPROM functions, reset behavior, and arbitration because the manufacturer application note identifies these functions as important compatibility considerations.

Key Differentiators
- Specified for asynchronous PCI-to-PCI bridging (vs 21150)
- Two-port PCI bridge interface (vs PI7C8150BNDE)
- Established 208-FQFP 28 mm by 28 mm package format (vs PI7C8150A)
Design Notes
Route the PCI bus as a controlled parallel interface rather than a general-purpose digital bus. Match data and control trace lengths where timing margins require it, preserve a continuous reference plane beneath every routed signal, and avoid plane splits or stub-heavy test pads. Review the manufacturer's clocking and termination guidance for the specific topology before committing the stack-up and impedance constraints.
Allocate the full 208-FQFP land pattern and verify the official package drawing before PCB release. The 28 mm by 28 mm body leaves less routing space than a typical mixed-signal IC, so place the device early in layout and preserve escape channels for PCI data, address, control, clock, power, and ground pins. Confirm the exposed thermal and power-pin requirements directly from the datasheet.
Do not treat every 8150-family or 21150-family bridge as automatically interchangeable. Diodes Incorporated application note AN079-P identifies minor pinout differences and states that asynchronous designs require the PI7C8150. It also calls out the serial EEPROM and hot-swap pins, so verify those functions, clocking behavior, reset requirements, and auxiliary signals before approving a replacement.
Provide low-impedance power and ground planes sized for the device's actual operating-current and switching requirements. Confirm input-voltage tolerances and per-pin power classifications in the manufacturer datasheet, then decouple each supply group as directed. Avoid routing return current through narrow signal traces because a conventional PCI bridge contains many simultaneous switching outputs.
Compliance Information
The component listing identifies the PI7C8150DMAE as RoHS compliant and lead-free. Automotive qualification, REACH status, halogen-free status, and conflict-minerals status require confirmation from the manufacturer.
