Features
Block Diagram
Wireless Interface Following the IEEE 802.11b Standard
Ethernet MAC Unit (EMU) Interfaces with 10/100-Mbit Ethernet Physical through a
Standard MII Port
Inter-networking Unit (INWARM) with Integrated ARM7TDMI
the Bridging Functions between Ethernet and Wireless Interfaces
WLAN MAC Unit with a Second ARM7TDMI RISC Processor and Integrated 128-byte
Transmit and 128-byte Receive FIFOs, for Wireless MAC Layer Functions
Glueless SRAM Interface for all MAC Operations, Supporting up to 16M Bytes of
Common External Memory Shared between Both Processors
Integrated 2 x 6K x 32-bit Internal SRAM Memory Banks, Used for Each Processor’s
Program Code and Data Space
Glueless Flash Memory Interface, Supporting up to 16M Bytes of Nonvolatile Memory
for Permanent Storage of Program Code
Enciphering/Deciphering of Wireless Data On-the-fly Ensures Maximum Privacy
of Data
The Integrated Physical Attachment Interface (PAI), Fully Supports Direct Sequence
Spread Spectrum and Frequency Hopping Spread Spectrum (2 Mbps) Physical-layer
Interfaces
The WLAN and Inter-networking Functions Can Be Changed and Updated Easily to
New Requirements Since They are Implemented in Microcode
