Product Overview
PI7C8152BMAE is a high‑performance 2‑port 32‑bit PCI‑to‑PCI bridge from Diodes‑Pericom, compliant with PCI v2.2 and bridge v1.1. It supports 66MHz max speed, asynchronous clock, 4 secondary bus masters and 4×128‑byte FIFO buffers. 160‑MQFP package, commercial temperature 0℃~+85℃, for embedded computing and telecom PCI bus expansion.
Core Advantages
Full PCI Specification Compliance
Supports PCI v2.2, bridge v1.1 and PCI power‑management v1.1, good compatibility with legacy PCI hardware.
Asynchronous Clock Support
B‑version enables independent clock for primary and secondary PCI buses, flexible system frequency configuration.
Multi‑Master & FIFO Optimization
On‑chip arbiter for up to 4 secondary masters; built‑in FIFO improves burst performance and reduces bus congestion.
Robust SMD Package
3.3V core, 5V‑tolerant I/O; 160‑MQFP SMD package for dense layout, commercial 0℃~+85℃ operating range.

Frequently Asked Questions
Q1: What do suffix “E”, “I”, “MA” mean for PI7C8152 series?
A: E = Lead‑free RoHS; I = Industrial grade (-40℃~+85℃); MA = 160‑MQFP package. PI7C8152BMAE is commercial grade (0℃‑+85℃); industrial model is PI7C8152BMAIE.
Q2: Difference between PI7C8152A and PI7C8152B?
A: PI7C8152A only supports synchronous clock (primary & secondary bus same frequency). PI7C8152B adds asynchronous clock, two ports can run at different frequencies for flexible system design.
Q3: What speed & bus width does PI7C8152BMAE support?
A: 32‑bit PCI bus, max clock 66MHz. B‑version supports asynchronous independent clock operation.
Q4: How many secondary bus masters can this bridge support?
A: Built‑in arbiter supports up to 4 secondary PCI masters, no extra external arbitration circuit needed.
Q5: Are there pin‑compatible replacement parts?
A: Pin‑compatible options: PI7C8152BMA(non‑RoHS), PI7C8152AMAE(sync‑clock only). Function‑compatible reference: Intel 21152. Hardware & firmware validation is required before replacement.
Q6: What FIFO buffers are integrated inside?
A: Total 4×128‑Byte FIFOs: two for posted memory transactions, two for delayed transactions, improving multi‑master bus burst performance.
Q7: How to get datasheet, footprint and bulk price?
A: Submit quick inquiry for datasheet, 160‑MQFP footprint drawing, stock check and volume quotation, reply within 24 hours.
