Application of Freescale sensor in consumer electronics

The core of this paper is that Freescale's sensors make the application of consumer electronics smaller, faster, more accurate and more power-saving.

has more than 30 years of sensor technology accumulation of Freescale, since the introduction of the Xtrinsic sensor solutions since 2010, has been continuously improve its product line, and strive to sensor systems smaller, faster, more accurate and less power consumption, is committed to providing customers with diversified, differentiated product portfolio, To meet the needs of multiple markets, including consumer electronics markets, is well received by customers.

MPL 3115A 2 Pressure sensor-more accurate

The Xtrinsic MPL 3115A 2 pressure sensor, which was officially produced in the third quarter of 2011, provides high-precision pressure and altitude data with a variable sampling rate of up to 140 Hz with extremely high accuracy, 30 cm resolution (20-bit measurement), The flexible output in meters or Pascal can be used for mobile devices, outdoor/indoor location services, medical and security applications. Other intelligent features include temperature compensation without additional software and direct read values for height, pressure and temperature, which can save a lot of development time.

Xtrinsic MPL 3115A 2 pressure sensor All compensation is completed in the chip, the main MCU does not need to use the compensation algorithm to continuously the height, pressure and temperature of the original data conversion, thus reducing the demand for the main MCU. This intelligent integration is significant for saving power consumption, when the MPL 3115A 2 is operating in standby mode with a power consumption of 2 micro-Ann, while the low power mode with a sampling rate of 1 Hz when the power consumption of 8.5 micro-Ann. Low power consumption also benefits from the optional sampling rate of the MPL 3115A 2 and the 32 FIFO (Advanced/First Out) sampled storage buffers with configurable interrupts to mitigate communication with the primary processor.

The Xtrinsic MPL 3115A 2 pressure sensor offers rich embedded functionality and flexible user-programmable options, and designers can benefit from their intelligence and unique performance. The MPL 3115A 2 is the only pressure sensor in the market with a built-in low dropout (LDO) linear regulator that minimizes the impact of coupling noise caused by power supply and any change in power supply voltage. Up to 30 cm resolution allows the pressure transducer to recognize subtle height variations. The direct output of the vertical height measurement does not require the pressure unit conversion of the host, and gives a very precise outdoor and indoor position. Xtrinsic MPL 3115A 2 is a high-precision and easy to develop excellent sensor products.
