1 Introduction
AI7688H integrates a 1T1R 802.11n Wi-Fi radio, a 575/580 MHz MIPSR 24KEc
1-port Fast Ethernet PHY, USB2.0 host, PCIe, SD-XC, I2S/PCM and 3 UARTs. AI7688H
provides two operation modes – IoT gateway mode and IoT device mode. In IoT
gateway Mode, the PCIe Express interface can connect to 802.11ac chipset for 11ac
dual-band concurrent gateway. The high performance USB 2.0 allows AI7688H to add
3G/LTE modem support or add a H.264 ISP for wireless IP camera. For the IoT device
mode, AI7688H supports SD-XC and USB2.0. AI7688H can support the I2S interface at
192kbps@24bits. In IoT device mode, it further supports PWM, SPI slave, 3
and more GPIOs.
