Overview[edit]

MT7622E is a highly integrated network router system-on-chip used for high wire

performance, home entertainment, home automation and so on.

MT7622E is fabricated with advanced silicon process and integrates a Dual-Core

ARM Cortex-A53 Core operating up to 1.35GHz and more DRAM bandwidth.

This SoC also includes a variety of peripherals, including SGMII, RGMII, PCIe 2.0,

USB2.0 (Host/Device), USB 3.0 (Host) ports, and 5-port 10/100 switch.

To support popular network applications, MT7622E also implements 2.5Gbps HSGMII

and 1Gbps RGMII Ethernet interface, embedded a 5-ports 10/100.
