Though consumers and move expenses on the products to cut down in the main electronic product by a wide margin, but in the field of cellular telephone and consumer products, micromotor system (MEMS) Still keep the powerful momentum. Success of MEMS sensor stems from several great demand factors, includes offering and possessing the ocular interface based on movement on the mobile equipment, offer the abundant, actual experience to user.

ISuppli a nearest report shows, it is estimated MEMS market will rise to 8,300 million dollars from 5,600 million dollars in 2006 in 2012. The investigation revealed, only 3% of the mobile phones adopted the acceleration sensor in 2001, because MEMS technical development and consumer's demand for enhanced user interface, by 2010, adopt the mobile phone quantity with speed pickup to increase sharply to 33%.

Consume the electronic exhibition (CES) in 2010 world Have, fly, think the intersection of Karl and semiconductor put out latest the intersection of movement and sensory technology, in order to promote, move use of consumption electronic product, experience. MMA8450Q acceleration sensor is a high-accuracy, high efficiency solution, it can lengthen the battery duration of the small-scale mobile equipment, and measure the function to catch rigorous movements through highly sensitive movements and the direction. Think of Karl MMA8450Q acceleration sensor through flying, while the developers of cellular telephone and other consumption electronic devices can be lengthening the battery life-span, integration strengthens the function, and improve the experience of the terminal user finally.

MMA8450Q acceleration sensor for mobile equipment of future generation such as intellectual mobile phone and intelligence to originally design. The ideals of this kind of characteristic, portability and battery life-span have made up and met market demand. In fly, think in the the intersection of intelligence and this dull and stereotyped reference design of Karl playing a key role the triaxial digital sensor.

This device offers a large number of embedded configurated functions, help OEM manufacturer to meet particular market and products demand, including the direction, pats, doubles click, beats, freely falling body and shaking detectability.

MMA8450Q sensor is a solution of 12 digits, adopt 3mm * 3mm * 1mm small volume to capsulate. Data supervisory functions to offer it intelligence, sample a built-in 32 Section /axle (X-axis, Y-axis, Z axis) First not enter first play (FIFO) The memory is buffered, in order to improve the electric-saving ability of the overall system, and support and accelerate the speed of response through reducing the host processor. The cooperation that embedded function and FIFO buffer uses, make the terminal processor analyze only the data required; Multiplex other sensors at the same the intersection of I2C and bus line at the same time, can prevent the data from being lost. The configurated power saving mode and waking up automatically / dormancy function of the products, can help the artificer to realize the best current consumption.

The goal of MMA8450Q acceleration sensor employs including the walkie consumption device, such as cellular telephone and long-range control equipment, and intelligence one, e-book reader (eReader) , surf the Net one, notebook computer, PMP and PDA,etc.. The activity in other application including medical treatment are employed is controlled, infer and assist in the boat location that navigates while employing, the position in motorcade's tracing measures, and the safety shutdown of power tool and small-scale electric apparatus.
