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: s 32-bit, 33MHz PCI operation

Development Tools Support
To minimize risk and lower your product development costs, PLX o ers 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.
