In the IoT market, solutions are becoming more complex and end users are demanding more functions and features. In addition, measures for battery life, cost reduction, and size reduction are also important, and there may be people who are worried about them every day.
For those who are concerned about such requests from users, we recommend Texas Instruments' (hereafter TI)'s "SimpleLink™ Series" wireless products. This series of products supports various wireless standards and features low power consumption and software reuse. In this article, we will explain the common features of the SimpleLink series products.
Three features of the SimpleLink series products suitable for IoT
TI's SimpleLink series offers a number of products consisting of microcontroller (MCU)/wireless products with a 32-bit Arm®-based core, supporting more than 10 wired/wireless communication standards. increase. It also has industry-leading technologies such as low power consumption, robustness, and security functions.
The main features are the following three points.
1. Low power consumption
The best feature is low power consumption. Each series has slightly different characteristics, so I will briefly introduce them.
CC26XX, CC13XX series
- A system that can detect sensor data even in ultra-low power mode
These products have their own sensor controllers, and it is possible to collect sensor information even when the main CPU is turned off and the microcomputer is in sleep mode. This function is ideal for those who are considering products that can be used for IoT services.
- low transmit and receive power
For example, in the case of CC1350, the built-in RX (receiver) and TX (transmitter) power is as follows.
RX
5.4mA (Sub-1GHz),
6.4mA (Bluetooth Low Energy, 2.4GHz)
TX
+10dBm: 13.4mA (Sub-1GHz)
+9dBm: 22.3mA (Bluetooth Low Energy, 2.4GHz)
+0dBm: 10.5mA (Bluetooth Low Energy, 2.4GHz)
CC32XX, CC31XX Series
- Abundant low power consumption modes
The CC3220 has three main modes for reducing power consumption, each of which reduces power by function.
See the document below for details. (CC3110 is Networking subsystem only)
CC3120, CC3220 SimpleLink™ Wi-Fi® Interneton-a chip™ Networking Subsystem Power Management
- Built-in DC/DC converter with wide supply voltage range
The power management subsystem has a built-in DC/DC converter to support a wide range of power supply voltages. This subsystem allows you to use the low power consumption modes mentioned above to extend battery life.
2. Supports a wide range of wired/wireless standards
It supports wireless standards such as Bluetooth® Low Energy, Wi-Fi®, and Sub-1GHz. Representative products and corresponding wireless standards are as follows.

3. Code can be ported to products in the same series
The SimpleLink Software Development Kit (SDK) enables application reuse from previous generations. Therefore, there is no need to start development from scratch, and new functions can be added to existing systems while reducing development time and costs.
For example, it can be easily ported even if the wireless standard needs to be changed due to a change in the installation environment.
For porting, I think that it is easy to imagine if you watch the video below.
Shorten design time with reference designs that include test data
The development/design work of electronic devices is extremely difficult and complicated, as well as requiring a lot of man-hours. If a problem occurs, you have to go back to the upper process and start over.
To simplify such development, it is a good idea to use reference designs provided by semiconductor manufacturers.
Of course, the reference design also has the disadvantage that it is difficult to come up with a unique color. In addition, it is not easy to reduce the size or add distinctive functions.
However, not all electronic devices require significant miniaturization or distinctive features, do they? If reference designs are used in the development of general-purpose electronic devices, the design/development period, challenges, and costs can be greatly reduced.
TI reference designs
TI offers a variety of reference designs. For example, for wireless-related solutions, the following reference designs are available and can be used free of charge.
In addition to the reference designs introduced here, more than 1000 reference designs are registered.
