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

• Supports 802.1f (IAPP) and Tap-Dance™ (Atmel proprietary roaming protocol)

• 2.5 V for Core and 3.3 V for I/O

• Different Packages, Depending on the Requirements
