MT7688
Overview
MT7688AN SoC is an appliance automation bridge. It integrates a 1T1R 802.11n Wi-Fi radio, a 580MHz MIPS® 24KEc™ CPU, 1-port fast Ethernet PHY, USB2.0 host, PCIe, SD-XC, I2S/PCM and multiple low-speed IOs in a single SoC. Visit the overview page to compare different smart home chipsets.
The MT7688 supports two operation modes – IoT gateway and IoT device mode.
In IoT gateway mode, the PCIe interface can connect to an 802.11ac chipset and be used as an 802.11ac dual-band concurrent gateway. The high performance USB 2.0 allows MT7688 to add 3G/LTE modem support or a H.264 ISP for wireless IP camera. The IoT gateway mode also supports touch panel and Bluetooth Low Energy, Zigbee/Z-Wave and Sub-1 GHz RF for smart home control.
In IoT device mode, MT7688 supports eMMC, SD-XC and USB 2.0 in addition to Wi-Fi high quality audio via 192Kbps/24bits I2S interface and VoIP application through PCM, as well as peripheral interfaces including PWM, SPI slave, 3rd UART and more GPIOs.
