Overview

As PCI gains momentum as the preeminent backplane standard, suppliers of

add-in cards of all types are rushing to get PCI versions to market. Continuing

its drive to provide single-chip PCI interfaces for every market, PLX offers

designers its PCI 9050 Bus Target Interface Chip for low cost adapters.

The PCI 9050 provides a compact, high performance PCI bus target (slave)

interface for adapter boards. It enables rapid, low cost conversion of Industry

Standard Architecture (ISA) adapters to the PCI bus. The PCI 9050 accelerates I/O

data movements on adapter boards from ISA’s nominal bus speed of 8 MHz,

5 Mbytes/second to PCI’s 33 MHz, 132 Mbytes/second data transfer capability.

For designers looking for a simple and painless way to convert their ISA

adapters, PLX offers the PCI 9050 RDK! It includes a PCI board designed with the

PCI 9050 chip, I/O daughter card connector for standard or custom functions, a

breadboard area, test headers, and a piggyback ISA slot that enables existing ISA

boards to be plugged into the PCI 9050 for software and hardware implementa-

tion. The PCI 9050RDK also includes a set of development software tools, includ-

ing PLXMon™ for PCI bus monitoring and debug, and example serial/modem

device drivers for Windows 95.™
