Claimed to be the world's smallest, fully integrated MEMS accelerometer, the MXC6226XC is based on MEMSIC's patented MEMS thermal technology. The company believes that it is the only production accelerometer on the market today using wafer- level packaging and the only single-chip MEMS accelerometer built on a standard 0.18µm CMOS process. The company claims that its price makes it accessible to designers of cost-sensitive systems like mobile phones, toys, games, cameras and domestic appliances. The accelerometer measures 1.2x1.7x1mm, or approximately 50% smaller than competitive offerings, says the company. It is available in a ball grid array package for integration into space-constrained designs. The signal conditioning circuitry includes a DSP for motion sensing. The two-axis digital accelerometer has no moving internal structures and exhibits high shock survivability of up to 50,000g, which is five times greater than the shock survivability of capacitive accelerometers. The digital accelerometer can detect four orientation positions, offers shake detection and can measure acceleration over a ±2g range with an absolute 0g offset of less than ±50mg. An I²C interface is for communications and an interrupt pin is provided for shake and orientation detection. Operating voltage is 2.5 to 5.5V and the temperature range is -20 to +70°C.
