Product Overview
The PCI9052G is a 32-bit 33MHz PCI target interface controller originally developed by PLX and now supported by Broadcom. It enables simple legacy ISA hardware migration to standard PCI v2.1/v2.2 without complex master-side design. This bridge chip supports configurable 8/16/32-bit local bus via external EEPROM, connects directly to FPGAs and MCUs with no extra logic, and features built-in bidirectional FIFOs for stable burst data transfer. Housed in lead-free 160-pin PQFP, it is widely used in medical devices, industrial backplanes and PCI expansion boards.
Core Advantages
Seamless ISA-to-PCI Migration
Dedicated decoding circuits convert 8/16-bit legacy ISA designs to standard PCI with minimal firmware modification.
Flexible Local Bus Configuration
Supports multiplexed/non-multiplexed bus layout with 4 programmable chip selects, compatible with various MCUs and FPGAs.
Independent Asynchronous Clock Design
Onboard high-speed FIFOs isolate local bus timing from the 33MHz PCI host clock for stable cross-domain data transmission.
RoHS Lead-Free SMT Package
Low-power CMOS 160-pin PQFP meets global green manufacturing and automated reflow production standards.

Frequently Asked Questions
Q1: Is PCI9052G 100% genuine new?
A: All chips are original PLX/Broadcom new stock. Every batch passes strict ESD QC and is shipped in factory trays to avoid pin damage.
Q2: What’s the difference between PCI9052G, PCI9052 and PCI9030?
A: G suffix stands for RoHS lead-free package; PCI9052G shares identical logic with standard PCI9052. PCI9030 adopts different bus structure with extra signal ports.
Q3: Does PCI9052G need an external local bus clock?
A: Dual clock domains separated by asynchronous FIFO. Local bus can sync with the 33MHz PCI clock or use an independent external oscillator for unmatched MCU/FPGA timing.
Q4: How to configure vendor ID and address windows on power-up?
A: The chip loads config parameters from external 93CS46 Microwire EEPROM after power on, including Vendor ID, Device ID and chip select ranges for automatic system identification.
Q5: Can I get free samples of PCI9052G for testing?
A: We support sample orders for project verification. You can submit sample demand via our inquiry form, we will confirm sample cost and freight within 24 hours.
Q6: What is the warranty period for PCI9052G?
A: All our ICs come with a 1-year quality warranty against manufacturing defects under normal operating conditions.
Q7: What is the lead time for mass orders of PCI9052G?
A: In-stock items ship within 1-2 working days. For out-of-stock bulk orders, the delivery cycle is 3-7 working days.
Q8: Is PCI9052G compatible with 5V and 3.3V peripheral devices?
A: Yes, the chip supports mixed 3.3V/5V signal level matching, compatible with most industrial MCUs and FPGA modules.
Q9: What packaging options do you supply for PCI9052G?
A: We only supply the standard 160-pin PQFP lead-free RoHS package as marked in the datasheet, no other alternative packages.
