Since 2021, with more and more attention paid to issues such as carbon neutrality and green economy in China, many enterprises have begun to integrate “carbon neutrality” into their development considerations. At the same time, many mechanisms to promote “carbon neutrality”, represented by the carbon trading market, are gradually developing and improving, bringing new huge market opportunities.

As an important part of the digital economy, the Internet of things industry and enterprises also play an important role in the process of carbon neutrality. According to the research conducted by the world economic forum on 643 Internet of things projects, 84% of these Internet of things deployments can achieve 17 sustainable development goals set by the United Nations. On the one hand, IOT technology can help effectively monitor, manage and reduce carbon emissions; On the other hand, the growing Internet of things also needs to pay attention to energy conservation and reduce power consumption.

Therefore, more and more IOT manufacturers are turning to wireless communication technology with lower power consumption. According to the data of Bluetooth SIG, from 2021 to 2025, the annual shipment of single-mode low-power Bluetooth devices will increase by three times; By 2025, it is estimated that 96% of Bluetooth devices will include low-power Bluetooth. Low power wireless technology has become the market choice.

IOT devices are realizing more complex functions

In many fields such as medical and health care, wearable, smart home and so on, emerging applications are emerging, such as intelligent blood glucose monitoring, medical identity certification, smart rings, bracelets and so on. These IOT applications not only have higher requirements for lower power consumption, but also become more complex in function. This requires that IOT devices can provide continuous and stable connections, advanced functions, and as long as possible, so as to avoid frequent charging or battery replacement on the basis of good use experience.

Take the blood glucose monitoring products whose market demand has increased rapidly in recent years as an example. These portable products are often wearable, and they want to have a very thin size and cling to the human body through soft plastic materials; But at the same time, reliable battery performance is required to provide monitoring function continuously for a long time. Therefore, the product needs to be in a low-power state for a long time while accurately completing the monitoring task, which puts forward very strict requirements for battery size, chip efficiency and power consumption.

Similarly, some other IOT devices have higher requirements for SoC computing power, security or storage specifications. For example, accurate positioning and direction finding devices will generate continuous data flow, requiring the processor to receive and process quickly while maintaining low power consumption. The fast and continuous access of such data needs to be based on stable device storage and requires certain performance and reliability. Therefore, sufficient ram and flash memory are indispensable. However, home automation equipment, such as smart door locks and smart switches, often have higher requirements for SoC security and battery life.

Atmospheric atm33 supports advanced applications with ultra-low power consumption

To meet the growing market demand, atmosic launched a new generation of Bluetooth in January 2022 ® 5.3 high performance system on chip (SOC) product atm33 combines its patented advanced energy collection and ultra-low power consumption technology to provide customers with wireless solutions with stronger processing power and lower power consumption.

The atmospheric atm33 supports the longest battery life and battery free operation to date, and has first-class wireless power performance. The battery life of this solution is 3 to 5 times that of competitive products.

Atm33 integrates power optimized arm ® M33f processor, operating frequency up to 64mhz, with DSP instruction function, and support arm TrustZone ®, It can provide strong system security. This new product series also supports Bluetooth Le 5.1/5.2/5.3 and aoa/aod indoor positioning technology, and has higher energy collection efficiency, wider energy collection input range, lower cold start voltage, lithium-ion battery and low-power voice processing.

In addition, atm33 series SOC also has sensorhub hardware module, which can complete data collection when most modules of SOC such as CPU are dormant. With sensorhub technology, customers can greatly reduce the wireless communication power consumption of sensors and extend the battery life of devices; At the same time, reduce the overall RF spectrum noise caused by the sensor competing for transmission or performing endless “retry” transmission; And further reduce the overall network and cloud service load of the system and the corresponding operating costs.

Through these technical advantages, in addition to being compatible with the functions of previous generation products, atm33 can also meet the more complex advanced application requirements in many fields, such as medical health, wearable, human-computer interface devices, home automation, etc., such as dynamic blood glucose monitoring, medical identity certification, smart hand rings / rings, precision orientation and direction finding devices, smart door locks / switches, etc.

Looking ahead

Looking forward to 2022, the ultra-low power Bluetooth market is expected to continue to grow, while home automation, wearable and other fields will also maintain an upward trend. With the continuous development of the Internet of things industry and more and more participation in the process of carbon peaking and carbon neutralization, its pursuit of higher performance and lower power consumption is bound to become more important.

As a global leader in wireless technology for energy collection of the Internet of things, atmosic will also continue to focus on the design of ultra-low power wireless technology and energy collection solutions to achieve the development of the permanent battery life and battery free Internet of things, and help reduce the impact of the Internet of things on the global overall ecological environment.
