Preliminary W89C926 PENTIC+ PCMCIA ETHERNET NETWORK TWISTED PAIR INTERFACE CONTROLLER
GENERAL DESCRIPTION
The W89C926 PENTIC+ is a CMOS device designed for easy implementation of PCMCIA R2.1 compatible CSMA/CD local area networks. The W89C926 combines a W89C902 Serial LAN Coprocessor for Twisted-pair (SLCT) with a PCMCIA Bus Interface (PBI), thus integrating into a single chip all the registers and logic necessary to connect the SLCT to buffer SRAMs, flash memories (or an EEPROM), and the PCMCIA system bus. The PCMCIA Bus Interface (PBI) is designed to provide a switchless setting architecture that allows the card setting to be configured by software. It implements a full set of PCMCIA registers for PCMCIA R2.
