EMW3162 is a low-power embedded Wi-Fi module integrates a wireless LAN MAC/baseband /radio, and a Cortex-M3 microcontroller STM32F205 that runs a unique "self-hosted" Wi-Fi networking library and software application stack. EMW3162 has 1M bytes flash, 128k RAM and rich peripherals for your embedded Wi-Fi applications. EMW3162 is also an mxchipWNetTM compatible platform; users can build their own embedded Wi-Fi applications based on mxchipWNetTM library which manage all of the Wi-Fi MAC and TCP/IP stack processing. We also provide several mxchipWNetTM firmwares to meet typical applications: wireless UART, wireless audio, wireless sensor etc. When using mxchipWNetTM-DTU firmware, you can establish Wi-Fi networking for any device with a micro-controller and a serial interface. Quick development cycles enable fast time to market. EMW3162 and EMW3280 are pin compatible.
