MediaTek MT7687F is a highly integrated single chip featuring an application processor, a low power 1T1R 802.11n single-band Wi-Fi subsystem and a power management unit (PMU).

Key features

  • Integrates 4kbit eFuse to store device specific information and RF calibration data
  • High integration with RF, MCU and memory
  • Low power mode with RTC

The application processor subsystem contains ARM Cortex-M4F MCU. It also includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC as well as embedded SRAM/ROM and a serial Flash in the package.

​The Wi-Fi subsystem contains the 802.11b/g/n radio, baseband, and MAC that are designed to meet both the low power and high throughput applications. It also contains a 32-bit RISC CPU that could fully offload the application processor.
