Overview
The MT7621 integrates a dual-core MIPS1004K (880MHz), HNAT/ HQoS/ Samba/ VPN accelerators, 5p GbE switch, 2xrGMII, USB3.0, USB2.0, 3xPCIe, SD-XC. The powerful CPU with rich portfolio is suitable for 802.11ac, LTE cat4/5, edge, hotspot, VPN, AC (Access Control). It can also connect to touch-panel, ZigBee/Z-Wave for Internet Service Router and Home Security Gateway. For the next generation router, MT7621 provides several dedicated hardware engines to accelerate the NAT, QoS, Samba and VPN traffic. These accelerators relief the CPU for other upper layer applications.
