PI7C8150BMAIE - 66MHz PCI Bridge | Diodes Incorporated
MPN: PI7C8150BMAIE ✓ সক্রিয়PI7C8150BMAIE সারাংশ
A PCI-to-PCI bridge is an interface IC within the broader PCI interface controller hierarchy. It translates and arbitrates transactions between two PCI Local Bus segments, allowing compatible peripheral cards and bus masters on the secondary segment to access resources through the primary segment. The PI7C8150B family supports asynchronous operation, meaning its primary and secondary buses do not have to operate from one shared clock.
The bridge's primary and secondary interfaces are both 32 bits wide, and the standard PI7C8150B supports operation up to 66 MHz. The PI7C8150B-33 family member provides a lower-frequency version rated to 33 MHz. A 3 V to 3.6 V core supply range supports integration into conventional 3.3 V PCI systems while avoiding the need for a 5 V-only interface arrangement.
In a PCI system, the bridge can separate bus traffic between processor-side and expansion-card segments. Its asynchronous architecture is useful when the two sides run at different clock rates or when independent bus timing is preferred. The 208-pin FQFP exposes the numerous address, data, control, arbitration, and power pins required by two full 32-bit PCI interfaces.
Typical uses include industrial PCI systems, embedded instrumentation, industrial control equipment, data-acquisition systems, and legacy PCI expansion platforms. In each case, the bridge must satisfy the PCI Local Bus electrical and transaction-routing requirements while preserving the intended peripheral ordering and arbitration behavior.
PCB design should provide the required 3.3 V supply decoupling and route the many high-speed address and data signals with short, continuous paths. The manufacturer's pin-description table should be used directly when assigning all 208 package connections and when checking board constraints for this large fine-pitch bridge.

সাধারণ ব্যবহার
PI7C8150BMAIE এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Industrial PCI Bus Segmentation, Embedded Data-Acquisition Systems, PCI Test and Measurement Equipment, Medical Instrument PCI Expansion, Networking and Communications Equipment, Legacy PCI Storage and Adapter Systems.
Industrial PCI Bus Segmentation
The PI7C8150BMAIE fits industrial controller architectures that divide a 32-bit PCI Local Bus into primary and secondary segments. Its two 32-bit interfaces and asynchronous bridge operation allow expansion-card traffic to be isolated behind the bridge while maintaining access to upstream system resources. The 66 MHz capability supports higher-performance legacy PCI equipment, while the 3 V to 3.6 V supply range integrates with conventional 3.3 V logic. Confirm system arbitration, ordering, and transaction timing against PCI Local Bus Specification Revision 2.2 before releasing the board.

Embedded Data-Acquisition Systems
The PI7C8150BMAIE is appropriate for embedded data-acquisition chassis that place acquisition peripherals on a secondary PCI segment. A transparent asynchronous bridge lets PCI cards communicate with the host-side bus without treating both segments as one electrical load domain. Both ports are 32 bits wide, and the standard family operates up to 66 MHz for systems requiring faster bus transactions. Its 208-FQFP construction demands careful high-speed routing and a continuous supply plane, making the manufacturer's package and reference-layout guidance essential during PCB implementation.

PCI Test and Measurement Equipment
Test and measurement instruments can use the PI7C8150BMAIE to connect legacy PCI measurement cards to a primary control bus. Independent asynchronous timing on the two sides helps accommodate legacy peripheral behavior while retaining a 32-bit data path. The 66 MHz maximum is relevant when the instrument must service higher-speed bus masters, and the 3 V to 3.6 V operating range supports conventional 3.3 V system logic. Validate signal integrity, arbitration latency, and expansion-card ordering as a complete system rather than evaluating the bridge in isolation.

Medical Instrument PCI Expansion
The PI7C8150BMAIE can divide a medical instrument's PCI expansion subsystem from its primary control bus, providing a structured path for compatible legacy cards. The two 32-bit ports and asynchronous operation support systems whose peripheral timing differs from the primary bus. At up to 66 MHz, the standard PI7C8150B family can serve demanding instrument architectures, but medical deployments require separate validation of electrical safety, regulatory, and reliability requirements. The bridge itself must be evaluated for thermal performance, supply integrity, and fault containment under the completed system specification.
সুপারিশকৃত
Networking and Communications Equipment
The PI7C8150BMAIE is suitable in communications equipment that retains a 32-bit PCI expansion architecture for legacy network, modem, or storage cards. Placing those peripherals behind an asynchronous bridge can organize bus traffic and allow independent timing between the system and expansion segments. The two 32-bit ports and 66 MHz maximum support the throughput expected from PCI-compatible adapters, while the 3 V to 3.6 V supply aligns with 3.3 V interface designs. Engineering review should include peripheral ordering, shared-bus contention, termination, connector routing, and system reset behavior.
সুপারিশকৃত
Legacy PCI Storage and Adapter Systems
The PI7C8150BMAIE provides a compatible path for systems combining a primary PCI processor bus with a secondary adapter segment containing storage or I/O cards. Asynchronous operation permits the bridge to manage transactions between independently timed bus sections, and the 32-bit primary and secondary paths preserve the architecture's required width. The standard family's 66 MHz rating offers more operating margin than the PI7C8150B-33 option for faster devices. Because the package has 208 connections, designers must follow the manufacturer pin table closely and validate signal integrity across connector and cable interfaces.

ডিজাইন নোট
The PI7C8150BMAIE operates from 3 V to 3.6 V, so the 3.3 V rail must remain within that range under transient and tolerance conditions. Place the required bypass capacitors at the device's supply and ground pins using the shortest practical paths. Provide a low-impedance reference plane and avoid splitting return paths beneath the 208-FQFP device. Use the manufacturer power-distribution guidance to determine the exact capacitor network and exposed-pad connection.
The package contains two full 32-bit PCI interfaces, making uninterrupted routing of address, data, control, and arbitration signals essential. Follow the manufacturer's recommended layer stack and topology, keep sensitive clock paths short, and avoid unnecessary stubs or test pads on high-speed nets. PCI connector and trace geometry should be reviewed as a complete signal-integrity problem, including return vias, connector pin assignment, and the separation of unrelated interface groups.
Use the manufacturer's clock and PCI interface requirements when configuring buffers, terminations, and topology. Because the PI7C8150BMAIE supports asynchronous operation, primary and secondary bus timing must still be checked independently rather than assuming identical edge relationships. Validate the final design with representative traffic covering arbitration contention, burst transfers, bus ownership transfer, error responses, and reset sequencing. These tests can expose timing problems that a simple signal-continuity check cannot reveal.
Do not substitute PI7C8150B-33 for a design requiring 66 MHz operation: its 33 MHz limit is 50% lower and can prevent correct operation at the intended PCI frequency. Also avoid treating a generic 208-pin interface IC as a replacement without a full pin, timing, and transaction comparison. Confirm the exact orderable suffix, package drawing, electrical limits, and lifecycle status before releasing production artwork or placing a manufacturing order.
