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:
