Atmels' USB Wireless LAN Media Access Controller

From Atmel Corporation
 

 
Atmel's AT76C503A is a single-chip USB controller that provides all the processing and functionality required for the Media Access Control (MAC) protocol of wireless LANs at up to 11 Mbps. It focuses on, but is not limited to the IEEE 802.11b (Wi-Fi) standard. The AT76C503A provides a glueless interface conforming to the 12-Mbps Universal Serial Bus (USB) specification and can control a variety of wireless physical interfaces. It integrates Wired Equivalent Privacy (WEP) in hardware, supporting both 64-bit and 128-bit encryption.

Smart card chips contain a microprocessor and/or memory. They are embedded in smart cards; portable devices that resemble credit cards but are used in applications such as banking and health care. Search by Specification | Learn more about Smart Card Chips
Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function. Search by Specification | Learn more about Digital Signal Processors (DSP)
Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator. Search by Specification | Learn more about Microcontrollers (MCU)
Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another.
