Advantages of CC1312R over CC1310 in the Internet of Things

1. CC1310 Introduction

CC1310 is a cost-effective ultra-low power RF device below 1GHz. The interior is highly integrated with active RF and MCU with ultra-low current consumption. This excellent performance can also be used in energy collection and long-distance transmission, even if it is powered by small button batteries. CC1310 combines RF standard platform and multiple physical layers, so it can integrate the powerful 48MHz Cortex ®- M3 microcontroller and ultra-low power RF transceiver are flexibly combined. In order to ensure flexibility and ultra-low power consumption, special ARM is used ® Cortex ®- The M0 wireless controller processes the low-level RF protocol commands in ROM and RAM separately. CC1310 not only integrates a complete RF system and DC-DC converter, but also is a highly integrated and high-performance ultra-low power consumption MCU. This MCU can be configured to process analog and digital sensors, so it can greatly delay its sleep time. CC1310 uses software processing to configure the power supply, clock management and wireless system. It will be convenient for use and development. The required software can be queried on TI's official website.

CC1310 supports frequency standards lower than 1GHz, such as 315MHz, 433MHz, 780MHz, 868MHz and 915MHz. It is generally called Sub 1GHz. Different countries have different frequency planning ranges. With the same transmission power, Sub 1GHz has better communication performance than 2.4GHz short-range wireless transmission technology. In particular, Sub 1GHz does not require high transmission rate and complex modulation, and the communication distance can reach several kilometers. Compared with WiFi 2.4 GHz, the communication distance of 315MHz is about 8 times of that. When the air speed is 50Kbps, the receiving sensitivity can reach - 110 dBm, and 0.625 Kbps can reach - 124 dBm.

2. CC1312R characteristics

CC1312R improves its own hardware performance while integrating CC1310 device features, including internal available resources, integrated master MCU performance, and AES128 bit and 256 bit encrypted accelerometers. Its main characteristics are compared as follows:

3. Outlook

In recent years, the Internet of Things has achieved explosive development. According to statistics, in 2000, only 200 million IoT devices in the world were connected to the Internet. By 2014, this number had doubled 50 times to 10 billion, but it was less than 1% of the global 1.5 trillion devices and objects. It is estimated that by 2020, the number of global networking devices will reach 26 billion, and the scale of the Internet of Things market will reach 1.9 trillion dollars.

CC1312 is a cost-effective ultra-low power consumption RF device below 1GHz. Its hardware supports a variety of standard protocol communication methods, such as sigfox and Contiki 6LoWPAN. At the same time, the physical layer meets IEEE 802.15.4 standards. A series of standards and private networking methods can be developed in combination with relevant information. At the same time, its sleep current is less than 1uA. Combined with its extremely high reception sensitivity, a button battery can ensure its communication distance is more than 20km, The service life of the ultra-low power battery can be as long as about 20 years, and it is fully applicable to wireless sensor networks, building and home automation, smart grids, smart homes, wireless meter reading, industrial detection and control, wireless medical access control and RFID, etc. to meet the needs of a variety of IoT scenarios.

4. Summary

The Internet of Things is a major development industry at present and in the future, and its demand is tens of billions. It is foreseeable that CC1312R will shine in the future physical network industry with its excellent hardware performance and ultra-low cost.
