PCI 9052

32-bit, 33MHz PCI Target I/O Accelerator for 32-bit, 40MHz

Generic and ISA Local Bus Designs

As PCI evolves in today's complex systems, PLX continues to provide market leading

high performance 32-bit PCI solutions. In this tradition, PLX offers the PCI 9052 I/O

Accelerator. The PCI 9052 brings PLX's industry leading experience in the world of PCI

designs to you in a way that is simple and convenient to use. The PCI 9052 is the ideal

choice for implementation of your 32-bit, 33MHz PCI bus target (slave) I/O Accelerator

designs for you 32-bit 40MHz, Industry Standard Architecture (ISA) local bus, or generic

designs.

Add Target Functionality with Ease

The PCI 9052 has the industry's most flexible local bus, which allows for multiple inter-

face options to a wide variety of memory and I/O devices. Combine that with fully tested,

PCI r2.1 compliance, and your design risk is virtually zero. The PCI 9052 has a set of

advanced features to provide high performance and flexibility in order to simplify your

design, such as four programmable GPIOs, local chip select, prefetch read ahead mode,

zero wait state bursting, and on-the-fly big/little endian byte conversion.

Move your ISA Designs Up to Leading PCI Capabilities with Ease

The PCI 9052 accelerates I/O data movement on adapter boards, from ISA’s nominal

bus speed of 8MHz, 5MBytes/second, to high-performance 33MHz, 132Mbytes/second

PCI data transfer. The PCI 9052 enables a simple, rapid, low cost conversion of ISA

adapters to the PCI. The PCI 9052 is a perfect fit for many networking, telecommunica-

tions, imaging, industrial, and storage applications:
