The concept of the Internet of Things (The Internet of Things) was put forward in 1999. It has developed rapidly in recent years. Relevant data indicates that the scale of the Internet of Things industry has exceeded 600 billion yuan in 2013, and is expected to be close to one trillion yuan in 2015. It is estimated that by 2020, there will be 50 billion connected terminals in the world, and a large number of M2M applications will emerge, and the Internet of Things will become a reality. Its definition is simple: all items are connected to the Internet through information sensing devices such as radio frequency identification for intelligent identification and management. The Internet of Things refers to a huge network formed by combining various information sensing devices with the Internet through a network, and can even be said to be "network everything."
Microchip has always been very concerned about the Internet of Things, and relying on its own technological advantages to achieve the ultimate in device integration and power consumption, jumping out of the price war, Mike Ballard, senior manager of Microchip's Home Appliance Solutions Division and cloud support project leader, said The ability to easily connect to many different low-power embedded devices is a major trend in the IoT market. Microchip's MRF family of Wi-Fi® modules makes it easy to add Wi-Fi capabilities to 8-bit, 16-bit and 32-bit MCUs with full application layer protocol stack functionality. Microchip's RN Series Wi-Fi modules integrate a protocol stack that supports certain IP service functions, allowing flexible connection to any MCU regardless of its storage space. Microchip's embedded Wi-Fi solution offers designers a wide range of general-purpose 802.11b/g options with the widest range of compatibility, distance and low power consumption of IoT applications.
According to Mike Ballard, to promote the development of IoT, Microchip advocates a full range of value-added customers, including a variety of hardware and software solutions to help customers design their IoT products, and provides a number of channels for customers to obtain sample code and design skills. To speed up the final product launch. Resources provided include application notes, reference designs, software libraries, and more.

The three elements of "network everything" to consider
It is undeniable that M2M and the Internet of Things will be the focus and direction of future industry development. It will completely change the work and lifestyle of the whole society - higher production capacity, higher work efficiency, easier and more convenient, A more harmonious life. To achieve a true Internet of Things, you need massive addresses, massive bandwidth, massive storage, and high communication intelligence and management intelligence. The three key factors that need to be considered at this stage are: communication standards, power consumption, and communication security.
Microchip has always been concerned about the communication technology of the Internet of Things. At this stage, various communication standards such as Bluetooth, infrared, WiFi, and ZigBee coexist, and there is no unified framework that can adapt to any transport layer, platform, and operating system. In this regard, Mike Ballard said that because many embedded designs have a lot of variables, no standard can meet all the needs of each product. Therefore, to ensure the functionality and robustness of the IoT design within a few years, all of these standards (and other standards) are still required.
In addition, the power consumption of wireless communication technology in the Internet of Things is also an important consideration. Microchip offers more than 190 PIC MCUs with ultra-low power (XLP) technology, which can be used with embedded Wi-Fi that can fully support IoT functions. Easily work with Bluetooth modules. XLP technology meets IoT's low power requirements, providing sleep currents as low as 9 nA and operating currents as low as 30 μA/MHz, and low-power peripherals with various low-power modes to maintain battery-powered IoT The node works for a long time. But this is only one aspect. Software and tools are at the heart of low-power design. Microchip offers a battery life estimator that simulates the life of an application designed with an XLP MCU; and an MPLAB® REAL ICETM power monitor that monitors the real-time power consumption of Microchip MCUs. Designers can use this to capture and diagnose code that causes excessive current consumption and modify it.
Mike Ballard finally stressed that security is also very important. There are several aspects to the security of IoT that require attention. The first is the outbound and/or inbound data transfer between the product or device and the Internet (cloud server). Its security is currently ensured by SSL/TLS, enabling secure sockets and/or AES encryption for packets in messages. This method is currently used by Internet communications such as credit card transactions and online banking. The second is how to ensure the security of data and information once they are saved to the cloud server. There are several security models, depending on the implementation. Implementations vary widely, and there are multiple ways to ensure information security. For example, for the server itself, software and hardware can share a security model.
