ASM330LHHTR Automotive 6-Axis Inertial Measurement

STMicroelectronic's ASM330LHH is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope with an extended temperature range up to +105°C designed to address automotive non-safety applications.

STMicroelectronics' family of MEMS sensor modules leverage the robust and mature manufacturing processes already used to produce the micromachined accelerometers and gyroscopes to serve both the automotive and consumer market. The ASM330LHH is AEC-Q100 compliant and industrialized through a dedicated MEMS production flow to meet automotive reliability standards. All the parts are fully tested with respect to temperature to ensure the highest quality level.

The sensing elements are manufactured using ST's proprietary micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.

The ASM330LHH has a full-scale acceleration range of ±2 g, ±4 g, ±8 g, and ±16 g and a wide angular rate range of ±125 dps, ±250 dps, ±500 dps, ±1000 dps, ±2000 dps, and ±4000 dps that enables its usage in a broad range of automotive applications. All the design aspects of the ASM330LHH have been optimized to reach superior output stability, extremely low noise, and full data synchronization to the benefit of sensor-assisted applications like dead reckoning and sensor fusion.

The ASM330LHH is available in a 14-lead plastic land grid array (LGA) package.
