STMicroelectronics has unleashed what it boasts as the industry's smallest 6-axis inertial measurement unit (IMU) qualified for automotive applications. The ASM330LXH features low-noise and improved output resolution, making it ideal for in-dash car navigation solutions that need accurate and reliable inertial sensors to optimise positioning and direction, even without a strong GNSS signal, stated the company.

Multi-axis gyroscopes and accelerometers, such as the 6-axis ASM330LXH, empower sophisticated dead reckoning software algorithms that calculate current position from a previously determined location updated by time, acceleration and change of direction. The device also targets on-board units for electronic road tolling and other vehicle telematics systems.

Built on the company's fab on its robust 8in manufacturing line using the proprietary THELMA micromachining process technology to integrate on the same silicon both a 3-axis acceleration and 3-axis angular-rate sensor (gyroscope), the device comes in a 3 x 3 x 1.1mm land grid array package. It offers selectable full-scale ranges of 2/4/8/16g and 125/245/500/1000/2000dps with 16bit synchronised data outputs, at six user-selectable output data rates, for both the gyroscope and accelerometer. An SPI digital output allows the trouble-free transport of sensor data to the MCU, and I2C is also supported. Energy efficiency is assured via power-down, low-power and normal power modes, ST added.

AEC-Q100 qualified for automotive non-safety applications, the ASM330LXH is a robust sensor [up to 10000g shock survivability] that operates over an extended industrial temperature range of -40¡ãC to 85¡ãC.
