    6-axis Inertial sensor hones vehicle navigation

    STMicroelectronics’ ASM330LHH automotive-grade inertial sensor uses dead-reckoning algorithms to calculate precise position from sensor data if satellite signals are blocked. The MEMS module combines in a single chip a 3-axis accelerometer and 3-axis gyroscope to deliver high-resolution motion tracking in advanced vehicle navigation and telematics applications.

    A device temperature range of -40°C to +105°C gives designers the freedom to locate electronic controls in hot areas, such as in smart antennas on the vehicle roof or near the engine compartment. The accelerometer offers a user-selectable full-scale acceleration range of ±2/±4/±8/±16 g, while the gyroscope provides a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000 dps. Low-noise operation allows greater measurement resolution by minimizing integration errors when positioning is reliant on sensors only.

    The ASM330LHH system-in-package has built-in temperature compensation that eliminates any need for external compensation algorithms over its operating range. It also includes an SPI/I2C host serial interface and an embedded 3-kbyte FIFO. The device comes in a 3×2.5×0.83-mm, 14-lead plastic LGA package.

    Engineering samples of the ASM330LHH inertial sensor will be available in Q3 2018, with volume production to begin in Q4 2018. Prices start at $5 each for lots of 1000 pieces.
