MXC6255XU: Fully Integrated Thermal Accelerometer
The MEMSIC Digital Thermal Orientation Sensor (DTOS) is the world's first
fully-integrated orientation sensor. Its operation is based on our patented
MEMS-thermal technology and is built using a standard 0.18um CMOS process.
DTOS contains no moving parts (such as a ball) and thus eliminates field-reliability
and repeatability issues associated with competitive products. It also eliminates the
"click" sounds typically heard in ball based orientation sensors. Shock survival is
greater than 50,000g. DTOS detects four orientations, shake and shake direction.
In addition, it provides X/Y axis acceleration signals with very low 0g offset. An I2C
interface is used to communicate with this device and an interrupt pin (INT) is
provided for shake and orientation. The DTOS also has a power down enabled
through the I2C interface.

The DTOS is packaged in a hermetically sealed 6-pin surface mount package (3 mm
x 3 mm x 1mm); the product is RoHS compatible and operates over -20~70℃
