STMicroelectronics ASM330LHHG1 6-Axis Inertial Measurement Unit
STMicroelectronics ASM330LHHG1 6-Axis Inertial Measurement Unit (IMU) features a 3-axis digital gyroscope and a 3-axis digital accelerometer with an extended temperature range up to +125°C, designed to address automotive non-safety applications. The ASM330LHHG1 is AEC-Q100 compliant and industrialized through a dedicated MEMS production flow to meet automotive reliability standards. All 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. At the same time, the IC interfaces are developed using CMOS technology, allowing the design of a dedicated circuit that is trimmed to match the sensing element's characteristics better. The ASM330LHHG1 has a full-scale acceleration range of ±2/±4/±8/±16g and a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000dps, enabling it for a broad range of automotive applications.
The device supports dual operating modes: high-performance and low-power. All design aspects of the ASM330LHHG1 have been optimized to achieve superior output stability, extremely low noise, and full data synchronization, thereby benefiting sensor-assisted applications such as dead reckoning and sensor fusion. The STMicroelectronics ASM330LHHG1 is available in an overmolded 14-lead plastic, land grid array (LGA) package.
