WFM-M697D is a Wi-Fi module based on the most advanced MediaTek chipset MT7697D, is a highly integrated single chip which features an application processor, a low power 1x1 11n dual-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The application processor subsvstem contains an ARM Cortex-M4F MCU. It also includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. It also includes embedded SRAM/ROM.
The Wi-Fi subsystem contains the 802.11a/b/g/n radio, baseband, and MAC that are designed to meet both the low power and high throughput application. It also contains a 32-bit RISC CPU that could fully offload the application processor.
The Bluetooth subsystem contains the Bluetooth radio, baseband, link controller. It also uses the same 32-bit RISC CPU for the Bluetooth protocols.
