- Implementation of MEMS motion sensing in consumer electronics ∙∙∙ Excellent high-resolution output and temperature sensor capabilities

December 21, 2011, Seoul — STMicroelectronics (NYSE:STM), a global semiconductor company in various electronic applications and a leader in Micro-Electro-Mechanical Systems (MEMS) used in consumer and portable electronics, has launched an ultra-low-power, high-performance 3-axis accelerometer measuring 2x2mm. Half the size of existing devices, ST’s latest family of accelerometers provides motion sensing capabilities for consumer electronics where power and size are critical, such as mobile phones, tablets, and game controllers.

ST's LIS2DH and LIS2DM accelerometer sensors provide accurate, high-resolution output in a full-scale range of ±2g/±4g/±8g/±16g and demonstrate excellent stability over time and temperature. This sensor family is equipped with the latest features, including 4D/6D orientation detection, motion detection, and two programmable interrupt signals that provide immediate alerts for falls and other situations.

ST's accelerometer sensor product, which solves the power issues of battery-operated portable devices, adopts a first-in first-out (FIFO) memory block for power-down mode and sleep mode, and more efficient power management. In addition, it has a built-in temperature sensor and self-test function, allowing customers to verify the sensor's functionality after assembling the board.

The LIS2Dx sensor is software compatible with ST's existing 3-axis accelerometer, allowing users to easily 'hot swap' and reduce application development investment costs.

ST's latest accelerometer sensors are currently in mass production, priced at $1.05 per unit for the LIS2DH and $0.98 per unit for the LIS2DM for orders of 1,000 units. Prices are negotiable for bulk orders. ST's full MEMS portfolio can be found at www.st.com/mems .
