MTK2622E
Overview
MT7622E is a highly integrated network router system-on-chip used for high wire performance, home entertainment, home automation and so on.
MT7622 is fabricated with advanced silicon process and integrates a Dual-core ARM® Cortex-A53 MPCoreTM operating up to 1.35GHz and more DRAM bandwidth. This SoC also includes a variety of peripherals, including SGMII, RGMII, PCIe2.0, USB2.0(Host/Device) ,USB3.0(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.
