1. Product overviewMJIOT-AMB-03 is a highly integrated single chip low-power 802.11n Wireless local

area network (WLAN) network controller. It integrates a ARM-CM4 kernel, MAC wireless

LAN, WLAN baseband and RF RF on a single chip. It can be a configurable GPIO

configuration is provided for the application and control of the Realtek RTL8710BN.

Integrated memory can complete all the functions of the WiFi protocol stack, also

provides application development to the memory and flash.

MJIOT-AMB-03 is a complete and self-contained WiFi network solutions can be run

independently, but also can be used as the machine mounted on the other host MCU run

on.MJIOT-AMB-03 as should only processor device when using our SDK, according to

customer demand for solutions, not only can be reduced to the whole product the price

can also facilitate the subsequent maintenance and upgrading.

In addition cases, MJIOT-AMB-03 is responsible for the wireless internet access WiFi

adapter bear task, you can add it to any design based on micro controller, connection is

simple, only through the I2C/UART/SPI/RTC/TIMER/GPIO hardware interface, and use the

AT that refers to the development of networking products can be realized.

The powerful MJIOT-AMB-03 on chip processing and storage can, which can make the

equipment through specific GPIO port integrated sensors and other applications, to

achieve the minimal system resources occupied by the development and operation of the

minimum.

Comment①：Deep Sleep Mode deep sleep mode off the power domain, including Cortex-M3

kernel system, clock, and SRAM regulator. In addition to awaken the peripherals off source service:

a wakeup pin and a low precision timer wake-up system. In addition to keep the wakeup pin is not

closed, which he all registers a system restart after the closure. Wake up。

Comment ② ： Deep Standby Mode closed deep standby mode including Cortex-M3 kernel,

system clock, and SRAM regulator. In addition to wake up the source is 4 GPIO and other

peripherals outside the system timer wake off. Only about 200 bytes of registers keep using wake

up, the other registers are turned off. The system is restarted, wake up。

Comment③：The Sleep Mode sleep mode shuts down the power domain, including the Cortex

-M3 kernel, and the system clock. The system does not need to be restarted to wake up

7. Module installation notesMJIOT-AMB-03using the onboard PCB antenna module is required for the surrounding

environment. Suggestions are as follows: 6-9mm do not place the antenna within the

surrounding antenna components within the antenna; don't put 3-5mm below the

influence of the antenna components, if there is a need to do floor clearance processing;

don't put as much as possible under the module components and high frequency signal

line。
