STMicroelectronics (ST) Releases Smart Living Solutions

China,2014year8moon7day——STMicroelectronics (ST; NYSE: STM), the world’s leading semiconductor supplier spanning multiple Electronic applications, recently released a number of smart living solutions:

· Next Generation Transmission Technology:Lower power consumption, completely changing the traditional power supply mode

· Smart Home Applications:Monitor indoor and outdoor environments and control home networking devices

· Wearable Applications:Real-time collection of environmental and biological information

Next Generation Transmission Solutions

As a next-generation power technology, wireless charging is a fast-growing application area in the electrical appliance industry. STMicroelectronics has launched a WPC-compliant[1]The Qi-standard wireless charging solution integrates a microprocessor core and power control peripheral circuits, and only uses one chip to meet all the requirements of the Qi technical specification, helping to reduce bill-of-materials costs. The screen displays the voltage and frequency status of the entire power supply system from the power transmission board to the power receiving equipment.

· With the widespread use of USB charging for mobile devices, there is a new charging specification called USB Power Delivery (USB PD). The specification enables users to charge more power-hungry appliances, such as laptops and monitors, via USB. Based on the USB PD compatible power control chip, STMicroelectronics can realize power transmission between circuit boards with USB, check the power supply device category of the power receiving end and the power transmitting end through the USB PD protocol, and provide the best power supply capacity (maximum 100W) for the target device. ).

· SiC (Silicon Carbide) has attracted wide attention in the industry. As the next-generation semiconductor material, this new technology can significantly reduce the power loss of power semiconductor devices. Power MOSFETs using silicon carbide technology can significantly improve the energy efficiency of power supply equipment such as switch-mode power supplies and DC-DC converters. ST’s first 1200V silicon carbide power MOSFET has the industry’s highest operating temperature rating of 200°C. Because of the extremely low increase in on-state resistance at high temperature, the new devices help improve system energy efficiency and reliability.

Smart Home Solutions

· Sensor nodes installed in various indoor and outdoor locations enable remote monitoring of the surrounding environment of the house. A leader in sensor and IoT technology, STMicroelectronics has released a laptop-based remote monitoring demonstration of the environment, with sensor nodes built in temperature sensors, humidity sensors, low-power microcontrollers, and sub-1GHz wireless transceiver chips , Ultra-low power DC-DC converter chips compatible with solar cells or thermoelectric generators. Remote environmental monitoring can help improve the work efficiency of home appliances such as air conditioners, and broaden the application scope of smart homes and smart offices.

· STMicroelectronics has released a network-based remote control for indoor and outdoor LED lighting. ST’s indoor lighting solution integrates PFC controller chip, LED controller chip, 8-bit microcontroller and Bluetooth communication chip, which can realize the brightness control of indoor lighting based on notebook computer. ST’s outdoor lighting solution integrates a digital power controller chip, a 32-bit microcontroller, and a sub-1GHz wireless transceiver chip, and controls the brightness through a 32-bit microcontroller development board (gateway) with an onboard LCD touch screen . STMicroelectronics offers a complete product portfolio for remotely controlled LED lighting applications, including all key components.

Wearable Technology Solutions

The wearable device market has experienced rapid growth in recent years. STMicroelectronics has launched a wearable device platform based on a 32-bit ARM® Cortex®-M microcontroller that integrates a variety of sensors (motion sensors, air pressure sensors, temperature sensors, humidity sensors, proximity sensors, and MEMS microphones), leveraging ST’s advanced technology and signal processing and data sensing technologies.

STMicroelectronics also announced a watch-style optical heart rate monitoring solution for smartwatches and fitness equipment. The solution uses an ultra-low-power 32-bit microcontroller, an accelerometer, a Bluetooth communication chip, and a wearable device chip. There is a wrist-facing LED light on the back of the wearable device shown, and the wearable device uses this LED as a light source, using a photodiode and a microcontroller to measure the light reflected from the user’s blood flow to determine heart rate. The communication chip sends heart rate data to a laptop or smartphone, where it is displayed on the Display for the user to view.

In addition, STMicroelectronics will introduce a high-precision 3D printer motor control solution with a built-in 32-bit microcontroller and multiple motor drivers, digital power solutions for improved AC adapters and switching power supplies, and faster development and the e-Design Development Kit to reduce development costs.
