　　【MT7688】

　　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.

　　Key features

　　MIPS24KEc 580 MHz with 64 KB I-Cache and 32 KB D-Cache

　　Supports up to 256MB RAM with additional SD-card storage

　　1T1R 2.4 GHz with 150 Mbps PHY data rate

　　Legacy 802.11b/g and HT 802.11n modes

　　1-port 10/100 FE PHY

　　SD-XC, eMMC, I2C, PCM, I2S(192K/24bits), PWM, SPI master/slave, UART lite, JTAG and GPIO
