MEMS accelerometer offers high mechanical stability

A 3-axis MEMS accelerometer, designed to deliver consistent and stable performance in portable applications, has been unveiled by STMicroelectronics.

"The innovative architecture of our new accelerometer represents a significant advance in the design of MEMS devices," said ST's Benedetto Vigna. "This next generation device addresses the need of the mobile industry for higher performance and stability in advanced motion sensitive applications."

The LIS2HH12 is housed in a small 2 x 2 x 1mm package. It has selectable full scale range of ±2, ±4 or ±8g and a 16bit digital output, an integrated temperature sensor, industry standard I2C and SPI interfaces, a wide analogue supply voltage range of 1.71 to 3.6V, and two programmable interrupt generators that help streamline system design.

In addition, the accelerometer offers a typical Zero-g level change versus temperature of ±0.25mg/C and a typical offset accuracy of ±30mg.

Engineering samples are available now. Volume production is due to commence in the first quarter of 2014.
