Enables high-precision navigation with automotive-grade 6-axis IMU
A high-accuracy 6-axis inertial measurement unit, the STMicroelectronics ASM330LHHXG1TR integrates a 3-axis accelerometer and 3-axis gyroscope. Ultra-low-noise, high-stability sensing delivers precise motion data for robust vehicle navigation and dead-reckoning systems.
The ASM330LHHXG1TR offers wide measurement ranges selectable up to ±16g for acceleration and ±4000°/s for angular rate, capturing both subtle motions and fast rotations. Combined with exceptionally low noise densities as low as 60µg/√Hz for the accelerometer and 5mdps/√Hz for the gyroscope, the inertial measurement unit (IMU) provides the high precision and time-synchronized six-axis outputs needed for accurate inertial navigation algorithms and vehicle dead-reckoning.
Embedded sensor-processing features further simplify integration. The IMU includes 16 programmable finite state machines for the fully configurable tasks for on-device motion detection. It also embeds a machine learning core to classify motion patterns in real time. A dedicated sensor hub interface and 3KB FIFO buffer allow the ASM330LHHXG1TR to gather timestamped data from external sensors and batch inertial data, offloading the host processor and improving sensor-fusion efficiency. For design flexibility, the IMU supports dual high-performance and low-power operating modes, enabling trade-offs between maximum precision and energy consumption.
