Features
• IEEE 802.11b MAC and Baseband for Supporting Standard Rates Up to 11 Mbps
• Wireless Interface Following the IEEE 802.11b Standard
• Wireless LAN MAC Unit with ARM7TDMI® RISC Processor
• Integrated 128-byte Transmit and 128-byte Receive FIFOs for Wireless MAC
Layer Functions
• Delivers Standard Wireless Networking to Any Host that Supports a Full-speed
(12 Mbps) USB Interface
• The On-chip Boot-ROM Implements the Device Upgrade Protocol (DFU) Spec Making
the AT76C505 Ideal for Low-cost Terminal Adaptors without Requiring External
Program Flash Since the Host Driver Downloads the Code During the Start-up Phase
• Support of an External Serial EEPROM for Configuration Settings
• Glueless SRAM Interface for All MAC Operations, Supporting Up to 1M Byte of
External Memory
• Integrated 6K x 32-bit Internal SRAM, Used for Fast Program Code Execution and
Temporary Storage of Data
• Glueless Flash Memory Interface, Supporting Up to 1M Byte of Nonvolatile Memory for
Permanent Storage of Program Code
• Wired Equivalency Privacy (WEP) in Hardware Supporting 64-bit and 128-bit
Encryption
• Hardware Implementation of Time Critical MAC Functions by the MAC Support Unit
(MSU) Guarantees Maximum Robustness
• The WLAN and Inter-networking Functions Can Be Changed and Updated Easily to
New Requirements Since They are Implemented in Microcode
• Supports 11 Mbps Rates with Automatic Fallback to 5.5, 2 and 1 Mbps
• 128-ball CABGA Package
• Low-voltage 3.3V Operation
• SPI Interface and 8 GPIO Pins
• Baseband Supports Antenna Diversity Algorithm
• Baseband Supports Japan Filter
• Baseband Supports Differential or Single-ended I- and Q-Baseband Signals
• Integrated 802.11b Baseband Processor
