Features
Wireless Interface Following the IEEE 802.11b Standard
Two Ethernet MAC Units (EMU) Interfaces with 10/100 Mbits Ethernet Physical Layer
Transceivers through Standard MII Ports
Dual ARM7TDMI
RISC Processor Architecture
Inter-networking ARM7TDMI (INWARM) with 16 Kbytes Program and Data Cache
Controls the Ethernet MAC Units and Provides the Bridging Functions between
Ethernet and Wireless Interfaces
WLAN ARM7TDMI (WLANARM) with a Dedicated 32 Kbytes Program Memory
Coordinates the 802.11b MAC Functionality
802.11b MAC Unit with 512-byte Transmit and 128-byte Receive FIFOs
SDRAM Interface Supporting up to 256 MBytes of External Memory Shared between
Both Processors
32-bit DMA Channels Are Used for Data Packet Transfers between the SDRAM and the
MAC Units
Enciphering/Deciphering of Wireless Data On-the-fly Ensures Maximum Privacy of
Data
SPI Interface and Eight GPIO Pins that Can Be Used As Slave-Select Pins
A Bootstrap ROM Is Used in the Initialization Phase by the WLAN ARM
to Execute a
Code Downloading Procedure from an SPI Flash to Its Internal Program Memory
UART with 16-byte Receive and Transmit FIFO and Programmable Baud Rate up to
921 Kbaud
(Atmel proprietary roaming protocol)
Different Packages, Depending on the Requirements
