The MT7687 combines low power consumption with high performance and security for Smart Home Appliances and other IoT applications

The MT7687 provides lower power consumption to ensure maximum performance with a minimal impact on device power. The MT7687 has the ability to transmit at a maximum power output of 21dBm, a level that exceeds comparable SoCs in the market for enhanced WiFi coverage for smart homes. In addition, security is achieved through AES and 3DES/SHA2 protocols as security engines. Additional MT7687 advantages include:

  • An ARM® Cortex®-M4 processor with FPU.

  • 1x1 802.11b/g/n WiFi subsystem designed for power efficiency and robust connectivity.

  • 192Mhz/200Mhz for Cortex M4.

  • Versatile peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC support diverse applications.

  • An embedded SRAM/ROM and a serial flash in package.

  • A compact module for Smart Home appliances/devices.

  • An integrated security engine that makes the appliances/devices more secure.

  • A developer-friendly platform with Open SDK.
