PI7C8152BMAE - 2-Port 66MHz PCI Bridge | Diodes
Teilenummer: PI7C8152BMAE ✓ AktivPI7C8152BMAE Übersicht
A PCI-to-PCI bridge is a specialized interface IC that connects a host-side PCI bus to one or more downstream PCI buses. It belongs to the hierarchy of PCI interface controllers, bus interface integrated circuits, interface devices, and semiconductors. By separating primary and secondary bus traffic through a bridging controller, the PI7C8152BMAE allows PCI-compatible equipment to extend a 32-bit PCI topology while maintaining compatibility with the Revision 2.2 bus specification.
The verified device characteristics include two PCI ports, 32-bit bus width, operation from 33 MHz to 66 MHz, PCI 2.2 compliance, PCI-to-PCI Bridge 1.1 compliance, and a 160-MQFP package. A related distributor listing also identifies 3.3 V operation and a 10 pF feature. These details distinguish it as a conventional, parallel-bus PCI interface solution rather than a serial PCIe controller.
The PI7C8152BMAE is applicable to legacy PCI expansion systems, industrial controller interfaces, embedded PCI equipment, data-acquisition platforms, and test systems that retain 32-bit PCI buses. In these systems, the bridge can isolate a secondary bus segment and support devices operating with the same 32-bit width and up to 66 MHz clock rate. System designers must also account for the bridge-specific interrupt, arbitration, and reference-clock requirements described by the manufacturer documentation.
PCB implementation is the primary design consideration. The 160-pin MQFP footprint requires a fine-pitch, high-pin-count land pattern, careful escape routing, and verified multilayer-board construction. Power, ground, clock, and high-speed parallel bus signals should follow the manufacturer’s recommended topology, with particular attention to return paths and trace-length relationships.
This page combines verified manufacturer and distributor information with package, compatibility, sourcing, and design guidance intended to help engineers evaluate the PI7C8152BMAE efficiently. Because the verified data does not expose a complete public pin table, the page does not reproduce guessed pin assignments; the manufacturer datasheet and product page remain the authoritative references for implementation.

Typische Anwendungen
PI7C8152BMAE ist geeignet für 6 Anwendungs: Legacy PCI Expansion Systems, Industrial PCI Control Equipment, PCI Data-Acquisition Systems, Embedded PCI Interface Platforms, PCI Test and Measurement Racks, PCI Network and Communication Adapters.
Legacy PCI Expansion Systems
The PI7C8152BMAE fits systems that retain the 32-bit PCI Local Bus and need a secondary bus behind a primary host segment. Its two-port bridge organization, operation up to 66 MHz, and support for synchronous and asynchronous transactions align with PCI Local Bus Specification Revision 2.2 and PCI-to-PCI Bridge Specification Revision 1.1. The bridge can isolate downstream traffic while preserving compatibility with installed PCI cards. Because it uses a 160-MQFP package, the implementation should follow the manufacturer land pattern and validate arbitration, interrupt routing, clock distribution, and power distribution before production release.
Empfohlen
Industrial PCI Control Equipment
PI7C8152BMAE is applicable to industrial controllers that retain a 32-bit PCI expansion architecture rather than moving to serial PCI Express. Its 66 MHz maximum bus rate and support for synchronous and asynchronous transactions provide compatibility with conventional PCI devices operating at 33 MHz or 66 MHz. The commercial-grade designation means that temperature range and regulatory requirements must be checked separately for the final enclosure. A successful design also requires controlled reference-clock routing, tested reset behavior, and full electromagnetic-compatibility validation rather than reliance on generic parallel-bus layout practices.
Empfohlen
PCI Data-Acquisition Systems
A PI7C8152BMAE-based measurement chassis can use a secondary 32-bit PCI segment to organize compatible data-acquisition, signal-conditioning, or communication cards. The bridge’s documented 66 MHz ceiling and Revision 2.2 local-bus support allow legacy acquisition peripherals to remain connected without redesigning them around a serial controller. The engineering trade-off is board complexity: a 160-pin MQFP implementation requires multilayer routing, careful clock distribution, and deliberate power and ground partitioning. Timing, bus loading, arbitration, and interrupt behavior should be verified with the actual card population and cable lengths.
Empfohlen
Embedded PCI Interface Platforms
The PI7C8152BMAE can bridge an embedded processor platform to one or more legacy PCI peripherals when the product architecture depends on the established parallel PCI bus. Its 2-port configuration permits downstream bus segmentation, while 32-bit width and operation at up to 66 MHz preserve compatibility with PCI Revision 2.2 devices. Embedded implementations should give special attention to power sequencing, reference-clock jitter, peripheral arbitration, and the availability of bus resources. The 28 mm by 28 mm MQFP also makes board area and escape-routing density important constraints.
Empfohlen
PCI Test and Measurement Racks
PI7C8152BMAE-based test racks can retain instrumentation modules that communicate over 32-bit PCI while presenting a segmented bus to the host computer. Supporting both synchronous and asynchronous transactions provides flexibility across the PCI Local Bus Revision 2.2 environment, including devices that use different transaction timing. Because parallel PCI performance can be affected by loading, clock integrity, and trace topology, the bridge should be evaluated with the intended module population. Signal-integrity measurements, bus functional testing, thermal testing, and documented configuration procedures are recommended before field deployment.
Empfohlen
PCI Network and Communication Adapters
The PI7C8152BMAE may be used in communication appliances that include multiple legacy PCI adapters, allowing a primary host bus to serve downstream networking or storage cards through secondary PCI segments. Its 2-port topology and 66 MHz maximum transfer rate support the operating envelope of 32-bit PCI Revision 2.2 devices. The bridge does not alter the data protocol of attached adapters; it provides bus connectivity and segmentation. Designers should verify supported transaction types, interrupt routing, clock distribution, and electrical loading for each adapter while also planning for legacy PCI supply availability and long-term obsolescence management.

Designhinweise
Use the exact manufacturer land pattern for the 160-MQFP package rather than creating a footprint from the 28 mm body dimensions alone. The MQFP leads are closely spaced, so every pin must have a practical escape path without requiring excessive vias or short segments between opposing rows. Confirm pin-one orientation, solderable land length, courtyard clearance, and assembly tolerances against the manufacturer drawing. A multilayer board is generally more practical for escaping this lead count while maintaining the reference-clock and parallel-signal routing quality.
Treat the PCI reference clock and the 32-bit parallel buses as high-speed signal paths. Route the clock from its source to the bridge without unnecessary stubs, and provide a continuous return path beneath each routed signal. Keep clock and data topology consistent between the primary and secondary buses because mismatched propagation can create functional failures even when the schematic is correct. The verified data does not specify trace impedance or allowable skew, so obtain those limits from the manufacturer documentation and validate them with the actual board stack-up.
Follow the manufacturer’s exact 3.3 V supply and decoupling topology for this legacy parallel-bus bridge. Place required bypass capacitors at the associated power pins rather than collecting them at a distant regulator, and provide low-impedance planes or paths for the return current. Because the supplied excerpts do not identify every power pin, voltage rail, or capacitor value, these details must be taken from the complete datasheet. Confirm startup current, sequencing requirements, and tolerance limits before releasing the power architecture.
Do not assume that a part sharing the PI7C8152B family name is an automatic drop-in replacement. Verify the complete terminal list, package drawing, PCI revision, clock behavior, reset requirements, temperature grade, and qualification status against the exact PI7C8152BMAE ordering code. This caution is particularly important for legacy Pericom cross-references because lifecycle, manufacturing status, and document revisions may differ. Perform board-level functional, timing, and thermal tests with the intended peripheral population before substitution approval.
Compliance-Informationen
The supplied distributor and manufacturer excerpts do not provide explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements. The PI7C8152BMAE is identified as commercial grade; AEC-Q100 is therefore recorded as not applicable rather than assumed.
