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 interface 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, telecommunications, imaging, industrial, and storage applications:
■ 32-bit, 33MHz PCI operation
■
32-bit, 40MHz local bus operation
Glueless ISA interface for low cost adapters
32-bit, 16-bit, 8-bit data lines
■
■
Local bus asynchronous
to PCI clock
■
Serial EEPROM interface for loading configuration
information, to simplify your switch from ISA designs
■
On-the-fly big/little endian
byte conversion
■
Based on the industry-leading architecture of the
PCI 9050, for easy software migration
■
– Redirects current word or byte
lane during 8- or 16-bit local bus
operation
■ Backwards compatibility with the
PCI 9050
■
Five local address spaces
independent from EEPROM
■
Four independently programmable local chip selects
■
Up to four programmable GPIOs

Development Tools Support
To minimize risk and lower your product
development costs, PLX offers Software
Development Kits (SDKs) and Rapid
Development Kits (RDKs) that support the
PCI 9052. These kits enable designers to
quickly bring new designs to production.
PLX recognizes that software often represents the largest investment in development.
The PCI 9052 is fully compliant with PLX’s
SDK-LITE that enables quick and easy development of high performance local processor
and host PCI software through standard
APIs, PCI debug tools, and sample drivers.
The PCI 9052 design support is provided
through RDKs that include a robust PCI
development platform, complete with
OrCAD schematics, documentation, a PCI
9052 chip sample, and software.
