| Description | PCI Target Interface Controller IC, 32‑Bit 33MHz PCI Bus to Local Bus Smart Target Bridge, Lead‑Free, 160‑PQFP Package. |
| Stock Status | In Stock |
| Origin | Original Factory |
Product Overview
The PCI9050‑1F is a cost‑effective 32‑bit PCI target bridge IC from PLX (Broadcom). It connects 8/16/32‑bit local‑bus hardware to PCI v2.1 without complex glue logic. Running at 33MHz, it integrates FIFO buffers, programmable chip selects, auto byte‑endian conversion and interrupt merging. This industrial‑grade 160‑pin lead‑free PQFP device is widely used for legacy industrial boards, DAQ modules and embedded system maintenance.
Core Advantages
Cost‑Effective PCI Target Bridge
Low‑power single‑chip solution linking local‑bus devices to 32‑bit / 33MHz PCI bus conforming to PCI v2.1 standard.
Flexible Local‑Bus Support
Works with multiplexed or non‑multiplexed 8/16/32‑bit bus, directly interfacing MCU, DSP and memory without extra peripheral logic.
Flexible Timing & Chip Select Configuration
Offers 5 local‑bus address spaces and 4 chip selects with programmable wait‑states to match different peripheral speed requirements.
Industrial‑Grade Reliability
RoHS lead‑free package with ‑40℃~+85℃ wide temperature range, delivering stable performance for industrial repair‑and‑replace applications.

Frequently Asked Questions
Q1: What is the main function of the PCI9050‑1F?
A: It is a dedicated PCI target controller bridging 32‑bit/33MHz PCI bus with local 8/16/32‑bit MCU, memory and ISA‑style peripherals.
Q2: What does the “F” suffix in PCI9050‑1F stand for?
A: “F” means lead‑free RoHS‑compliant 160‑pin PQFP package.
Q3: Does PCI9050‑1F support PCI Bus Mastering?
A: No, it works only as PCI target. For bus‑master DMA function, select PCI9054 or PCI9056.
Q4: What near‑compatible alternatives are available for PCI9050‑1F?
A: PCI9050‑1 (tin‑lead) is pin‑to‑pin compatible but non‑RoHS. PCI9052 has similar functions yet different registers; firmware modification is required, not direct drop‑in replacement.
Q5: PCI9050‑1F vs PCI9054, what is the core difference?
A: PCI9050‑1F is target‑only for legacy repair with lower cost. PCI9054 supports target and bus‑master DMA for high‑speed transfer; pinout differs and cannot substitute directly.
Q6: Can I use third‑party clone PCI bridge IC to replace PCI9050‑1F?
A: Third‑party chips may share partial features, while registers, interrupt and timing often mismatch. Original PLX/Broadcom part is recommended for legacy industrial board repair to avoid compatibility risks.
Q7: How to get datasheets, register docs or bulk quotations?
A: Submit request via Quick Inquiry form. Our sales‑engineering team will send datasheets, stock check and pricing within 24 hours.
