Mouser Electronics has announced the shipping of new WINC1500 Wi-Fi Module from Atmel Corporation. The WINC1500 is a low-power consumption 802.11 b/g/n WiFi module specifically optimized for low power Internet of Things (IoT) applications. This WiFi module supports WEP, WPA, and WPA2 WiFi security encryption as well as China WAPI security while drawing as small as 4µA. It allows both WiFi and Bluetooth signals to coexist locally without any signal interference.
This highly integrated device includes an integrated power amplifier, low noise amplifier (LNA), all necessary power management functions, and an integrated antenna. The WiFi module targets low power WiFi wireless applications and draws only 4µA in Deep Power Down mode; at beacon monitoring mode the module draws only 850µA in Doze Mode. This module 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 signaling interface. The interface allows this module to coordinate transmission and reception with a compatible Bluetooth module to insure that both radios do not interfere with each other. It also features a small form factor at only 21.5 x 14.5 x3.4 mm.
This WiFi module is based on a powerful Cortus-APS3 32-bit processor. The 32-bit processor performs hardware accelerated MAC functions including association, authentication, power management, security key management, and MSDU aggregation/de-aggregation. The processor also 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.
