across multiple electronic application in the field of semiconductor supplier stmicroelectronics will appear in 2013 Japan's cutting-edge technology exhibition (schoolNO - faceIER). In time, 1 d - stmicroelectronics booth no. 201, visitors will see a variety of power and sensor application demonstration and development board. Semiconductor power solutions help to improve the efficiency of energy use, the use of sensor solutions can improve the user experience, increase the customer value products, help to achieve new way of life.

Sensor solutions

Perceive our environment and home environment information, use the awareness to improve the life quality of the environment information, sensor application is becoming a professional media hot words. The next generation of household system with awareness and wisdom will help us to detect temperature, humidity, gas and smoke, let our life safer, more comfortable, more efficient. Stmicroelectronics in cutting-edge technology exhibition booth will show environment of MEMS sensors, including the ability to detect environmental information of pressure sensors, temperature - humidity sensor.


Stmicroelectronics high precision pressure sensor is especially suitable for portable devices, low power consumption good to test the accuracy of the portable devices in accurate location of stair steps. Stmicroelectronics pressure sensor and determination of plane position (the longitude and latitude) of global navigation satellite system (GNSS) receiver, which can realize 3 d positioning and mobile location services, expect the two services will usher in rapid growth. Temperature and humidity sensor can be used in air conditioners, refrigerators and other appliances or family, factory, building automation systems, promote family intelligent building process.


MEMS microphone contribute greatly to improve sound quality, the business is high-speed growth. In both size, durability, and in terms of power consumption, MEMS microphone is better than traditional electret condenser microphone. Active noise suppression performance of MEMS microphone arrays are great. Stmicroelectronics booth will hold a voice audio engine were used to detect the external environment and suppress noise application demonstration, the audio engine contains matching and frequency response sensitivity are extremely small size MEMS microphones.
Audio engine, give full play to the excellent properties of stmicroelectronics MEMS microphones, using high-performance and nc active feedback and positive feedback to deal with the noise suppression technology to eliminate redundant environmental noise, natural and comfortable listening experience for users, as if not wearing headphones. By monitoring the ears of the acoustic environment, the presentation will provide even more clear voice quality.
Power solutions

Replace the power cord charging wireless charging technology is rapidly spread. The technology bring more convenience to users, and help to save resources. Stmicroelectronics booth will demonstrate the power of a wireless charger end solution (WPC), the scheme adopts the world's first programmable digital power controller STLUX385A.

STLUX385A monolithic integrated cost-effective stmicroelectronics Watson Wchangeorganisation microprocessor kernel and a set of unique variety of wireless charging standard peripherals. Before the advent of STLUX, wireless charger power circuit also need multiple discrete device, in order to satisfy a variety of charging standards and the requirements of technical specification, equipment manufacturers must also modify power circuit configuration for each standards. STLUX385A in the implementation of the first high-speed growth of the market to support multiple standard, allowing full custom architecture and high portability WPC platform, help to simplify the control performance and adaptability.

Ac adapter and switching power supply (Ssyhalt) is widely used in personal computers, game consoles and consumer electronic equipment and other electronic products. As energy costs rise, the global greenhouse effect limit, reduce the energy consumption of ac adapter's new regulations, power equipment manufacturers are trying to improve energy efficiency.

By using numerical control type STLUX385A in traditional power system, can be in different load conditions and to optimize the design of the improvement of energy efficiency. Semiconductor booth care method, adjust and modify via personal computers STLUX385A program and parameters, users can see waveform and changes in performance under different load conditions.

In addition, stmicroelectronics can be realized on a portable device will also show the touch-sensitive touch screen controller IC, 1 impacte for sensor node communication under wireless transceiver ICfiber1 chip level and high performance motor control system. Among them, the motor control chip integrates control all the digital control and analog measurement function and power electronic circuits.
