Introduction：
The MT7681 is a highly integrated Wi-Fi SoC(system on Chip) single chip, which supports IEEE802.11b/g/n single stream, providing GPIO and PWM for intelligent control, and UART, SPI, and I2C interfaces for device communication. The MT7681 integrate power amplifier, low noise amplifier, and RF switch to reduce the module size and RF design capability required. And also integrate power manage unit for single 3.3V power source for cost effective design. The MT7681 embedded 32-bit RISC MCU for 802.11b/g/n drivers, supplicant, TCP/IP protocol stack, and networking applications, can be operated in station mode and softAP mode. The MT7681 is an ideal solution for embedded device to enable networking service with minimized design effort. All the features are available in compact 40pin, 5x5mm QFN package.
