Murata Adds Internet To Home Appliances With WiFi Controller Modules

The self-contained module utilizes Broadcom Corporation’s Wireless Internet Connectivity for Embedded Devices architecture to provide comprehensive firmware and software features including a built-in Wi-Fi security supplicant supporting WPA PSK and WPA2 PSK, TCP/IP network stack and a simple network interface card protocol that supports socket connections.



The SN8200 is equipped with a STM32 ARM Cortex-M3, an on-board antenna and offers both UART or SPI connectivity to the host application. The ability to support sensor applications is also possible by using the module’s ADC, DAC, I2C and GPIO interfaces.



The SN8200 can operate in either access point or station mode. An integrated web server available in AP mode makes target device setup and control extremely easy. Output power is typically +18 dBm when operating in 802.11b mode at 11 Mbps.



The module is ideal for end-product designers wishing to quickly design-in internet connectivity to their product without needing to become involved in designing and certifying their own Wi-Fi transceiver. Using this approach a designer can rapidly add an internet-based control and reporting capability to any smart home appliance or industrial control equipment.
