Description 
 
Atmel ATWINC1500B is a single chip IEEE 802.11 b/g/n Radio/Baseband/MAC 
network controller optimized for low-power mobile applications. ATWINC1500B 
supports single stream 1x1 802.11n mode providing up to 72Mbps PHY rate. 
ATWINC1500B features fully integrated Power Amplifier, LNA, Switch, and 
Power Management. ATWINC1500B also features an on-chip microcontroller 
and integrated Flash memory for system software. Implemented in 65nm CMOS 
technology, the ATWINC1500B offers very low power consumption while 
simultaneously providing high performance and minimal bill of materials. 
The ATWINC1500B supports 2- and 3-wire Bluetooth coexistence protocols. 
The ATWINC1500B provides multiple peripheral interfaces including UART, SPI, 
2
I C the only external clock source needed for the ATWINC1500B is a high-speed 
crystal or oscillator with a wide range of reference clock frequencies supported 
(12-40MHz). The ATWINC1500B is available in QFN packaging.
