PCI9052 G

Specialized Overview

The PCI9052 G is a 32-bit, 33MHz PCI Target I/O Accelerator designed for 32-bit, 40MHz generic and ISA local bus implementations. It operates on a single 5V power supply and supports data transfer rates up to 132MB/s. The device features a 160-pin PQFP package and functions as a PCI r2.1 compliant target. It provides five independent local address spaces and four programmable local chip selects. The local bus supports multiplexed or non-multiplexed configurations with 8-, 16-, or 32-bit widths.

Specialized Feature Summary

• Glueless ISA interface enables low-cost conversion of legacy ISA adapters to PCI
• Zero wait state burst operation allows unlimited PCI transfers at peak performance
• On-the-fly big/little endian byte conversion redirects word or byte lanes during 8- or 16-bit operations
• Serial EEPROM interface facilitates configuration loading and mode switching

Specialized Applications

• Networking adapter designs
• Telecommunications equipment
• Industrial control systems
• Imaging applications
• Storage solutions

Specialized Procurement Notes

Verify the component status before procurement planning. Official documentation indicates this product has reached end-of-life status. Availability is restricted, and distributors may not stock this item in all regions. Confirm current supply constraints directly with authorized vendors prior to initiating any design-in processes.

Specialized Selection Notes

Select this component when migrating existing ISA-based hardware to modern PCI architectures. It is suitable for designs requiring asynchronous local bus operation independent of the PCI clock. Ensure the application utilizes 5V logic levels compatible with the specified CMOS package requirements.

Specialized Part Context

This part belongs to the PLX Technology PCI90xx series of I/O accelerators. It is based on the industry-leading architecture of the PCI9050, ensuring backwards compatibility and simplified software migration. Broadcom Limited acquired PLX Technology, making it the current manufacturer of record.
