It supports WEP, WPA, and WPA2 WiFi security encryption as well as China WAPI security while drawing as little as 4 µA. This module includes features that allow both WiFi and Bluetooth signals to coexist locally without any signal interference.
The 21.5- x 14.5- x 3.4-mm device 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.
