| PCI 9050 Bus Target Interface Chip Features I PCI Specification 2.1 Compliant Target Interface Chip supporting low cost slave adapters to five local bus address spaces and four chip selects FIFO for zero wait-state burst operation Bus transfers up to 132 Mbytes/second multiplexed and non-multiplexed 8-, 16-, and 32-bit generic local buses bus runs asynchronously to the PCI clock Big/Little Endian byte conversion power CMOS in 160-pin PQFP package I Up I Bi-directional I PCI I Supports I Local I Supports 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 implementation. The PCI 9050RDK also includes a set of development software tools, including PLXMonTM for PCI bus monitoring and debug, and example serial/modem device drivers for Windows 95.TM I Low Direct Slave PCI Interface Chip Speeds the Inevitable Disappearance of the ISA Bus PCI 9050 Block Diagram CLK RST# INTA# LOCK# Local Bus AD[31:0] C/BE[3:0]# PAR FRAME# IRDY# TRDY# STOP# IDSEL DEVSEL# PERR# SERR# PCI 9050 Serial EEPROM EESK EEDO EEDI EECS LAD[31:0] LA[27:2] LBE[3:0]# LINTi1 LINTi2 LCLK LHOLD LHOLDA LRESET# BCLKO CS[1:0]# USER0/WAITO# USER1/LLOCK# USER2/CS2# USER3/CS3# ADS# BLAST# LW/R# RD# WR# LRDYi# BTERM# ALE MODE PCI Bus Interface PCI Bus I/O Controller Memory PLX Technology, Inc. 870 Maude Ave. Sunnyvale, CA 94085 USA Tel: 1-800-759-3735 Tel: 1-408-774-9060 Fax: 1-408-774-2169 Email: info@plxtech.com Product Ordering Information PCI 9050 PCI 9050RDK PCI Bus Target Interface Chip PCI 9050 Software Development Kit (c) 2000 PLX Technology, Inc.
