MT7620 DATASHEET

Integrated 802.11n MAC/BBP and 2.4 GHz RF/FEM Router-on-a-Chip

Overview

The MT7620 router-on-a-chip includes an 802.11n MAC and baseband, a 2.4 GHz

radio and FEM, a 580 MHz MIPS® 24K™ CPU core, a 5-port 10/100 switch and two

RGMII. The MT7620 includes everything needed to build an AP router from a

single chip. The embedded high performance CPU can process advanced

applications effortlessly, such as routing, security and VoIP. The MT7620 also

includes a selection of interfaces to support a variety of applications, such as a

USB port for accessing external storage.
