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
