Atmel’s WiFi and Bluetooth combo module at Mouser
It supports WEP, WPA, and WPA2 WiFi security encryption as well as China WAPI security while drawing as little as 4µA. This module includes features that allow both WiFi and Bluetooth signals to coexist locally without any signal interference.
The 21.5×14.5×3.4mm unit includes an integrated power amplifier, low noise amplifier (LNA), all necessary power management functions, and an integrated antenna. It provides SPI, UART, and I2C host interfaces for communicating with a host microcontroller.
It also supports 2-wire and 3-wire Wi-Fi/Bluetooth coexistence signalling interface. The Atmel WINC1500 is based on a Cortus-APS3 32-bit processor which performs hardware accelerated MAC functions including association, authentication, power management, security key management, and MSDU aggregation/de-aggregation.
In addition, the processor provides flexibility for various modes of operation, such as STA and AP modes. An on-chip IP stack minimizes the host microcontroller requirements and supports TCP, UDP, DHCP, ARP, HTTP, SSL, and DNS.
