And also integrate power manage unit for single 3.3V power source for cost effective design.The MT7681 embedded 32-bit RISC MCU for 802.11b/g/n drivers, supplicant, TCP/IP protocol stack, and networking applications, can be operated in station mode and softAP mode. The MT7681 is an ideal solution for embedded device to enable networking service with minimized design effort.All the features are available in compact 40pin, 5x5mm QFN package.1.2 FeaturesSingle stream IEEE 802.11 b/g/n32-bit RISC microprocessor as the host MCUEmbedded IEEE 802.11b/g/n drivers, supplicant, and TCP/IP stackHighly integrated RF PA, LNA, and RF switchIntegrate high efficiency switching regulator for single 3.3V power sourceSecurity support for WFA WPA/WPA2 personal, WPS2.0, WAPIOperation in station mode or softAP modeRich interfaces, UART, SPI, I2C, PWM and GPIOsAll functions integrates in compact 5mm x 5mm QFN40L packageUART interface1.3 ApplicationsHome automationSmart plugLightingMeteringRemote controlNetwork consumer devices1.4 Block DiagramRF_INRF_OUTPGPIO/LED RF_OUTNFigure 1 MT7681 block diagram2Product Descriptions2.1Pin LayoutB G _E X T RR F _L D OR F _L D OX T A L _X IX T A L _X OR F _L D OP L L _L D OV D D 33V D D 12G P I O 0GPIO1 GPIO2 GPIO3 GPIO4UART_TX UART_RX LDO_RST_N PMU_PHASE PMU_V33 PMU_COMPF L C L K V D D 12G N D G N D G N D G N D P M U _12V P M U _V 15A P M U _V 33P M U _F BFigure 2 Top view of MT7681 QFN pin-out.2.2 PIN DescriptionTable 1 Pin descriptions2.3 Strapping optionTable 2 Strapping option2.4 Package Information 2.4.1 QFN PackagingFigure 3 Package outline drawing2.5 Ordering InformationTable 3 Ordering information 2.6 TOP Marking InformationFigure 4 Top marking3 Electrical characteristics3.1 Absolute maximum ratingTable 4 Absolute maximum ratings 3.2 Recommended operating rangeTable 5 Recommended operating range 3.3 DC characteristicsTable 6 DC description3.4 Thermal characteristicsNote:[1] Air flow condition: Natural convection. 0.5m/s.[2] PCB dimension 21mm x 11mm. 4-layer.[3] 5mm x 5mm QFN40L packageTable 7 Thermal information3.5 Current consumptionNote: All result is measured at the antenna port and VDD33 is 3.3VTable 8 WLAN 2.4GHz Current Consumption。
