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.

FEATURES

• Runs with NE2000 TM or shared memory drivers

• Supports up to 128 KB flash memory (8K/112K for attribute/common memory) or 512 bytes EEPROM (for attribute memory only) for nonvolatile memory

• Uses one 16 KB SRAM or one 32 KB SRAM (if EEPROM is used) for 16 KB Ethernet ring buffer

• Auto-load algorithm provided for power-on initialization

• Supports necessary PCMCIA registers

• Configuration registers allow switchless card setting

• UTP/BNC auto media-switching function provided

• Drives necessary LEDs for network status display

• Single 5V power supply with low power consumption

• 100-pin thin package (TQFP) fits into PCMCIA Type II profile
