China, November 3, 2015 – STMicroelectronics (ST; NYSE: STM), a leading global semiconductor supplier across multiple electronic applications, demonstrates an advanced and energy-efficient connected smart city technology. The concept of a smart city is to use sensors, networks and data processing technologies to improve energy efficiency and productivity throughout the city, not only to use energy more efficiently, but also to improve the management, utilization and maintenance of buildings and utilities. .

　　STMicroelectronics takes a smart city environment that connects multiple wireless sensor networks with multiple sensor nodes as an example to fully demonstrate the important role of sensors. These sensor nodes perform functions such as intelligent lighting system monitoring, smart garbage monitoring, smart vibration detection, and intelligent environmental monitoring.

　　STMicroelectronics uses a wireless grid sensor network to detect wirelessly controlled car models using proximity detection sensor nodes, and adjusts the brightness of the street lights according to the location of the car; detects the vibration of the building by accelerating the sensor nodes; and installs the surrounding environment The sensor node measures temperature, humidity and pressure; the wirelessly connected lighting control panel monitors the power consumption of the light in real time. Data from all sensor nodes will be transmitted to a display via the network for easy viewing. The design is based on ST's 32-bit microcontroller development board and a variety of sensors, such as RF transceivers and power management chips for wireless full mesh networks built with Paradox Engineering [1] communications platform.

　　Engineers can also experience ST's latest embedded development ecosystem, using Nucleo 32-bit micro-control development boards and X-Nucleo expansion boards, as well as ST's motion MEMS sensors, environmental sensors, MEMS microphones, motor drives, and low-power Bluetooth (BLE) chip and dynamic NFC tag. The purpose of developing an ecosystem is to make the development of smart cities and IoT applications faster and easier.

　　In order to adapt to the various specifications of many electronic products that have been mass-produced, the development of power adapters has become more diversified, and the demand for simple and easy-to-use power solutions has been increased. In the field of wireless charging, STMicroelectronics has introduced an advanced multi-platform digital power controller chip that meets the two wireless charging alliance standards of Qi and PMA. Other ST's solutions include: stand-by-power monitoring solutions for multi-mode power control chips for tablet and smartphone chargers, and the new 1200V silicon carbide (SiC, silicon carbide) ) Power MOSFET.

　　As the world's leading MEMS supplier, ST has the most advanced sensor solutions, including a 6-axis MEMS sensor module evaluation board with integrated 3-axis digital output accelerometer and 3-axis gyroscope for a compact package size (2.5 x 3.0 x 0.8 mm) and 20% more energy efficiency than competing products; and speech recognition applications based on MEMS microphones and smart low-power Bluetooth network processors.

　　STMicroelectronics teaches people how cutting-edge technologies can realize smart city concepts and the impact of smart cities on our daily lives.
