STMicroelectronics has expanded its portfolio with a device that combines three-axis sensing of both linear and angular motion. The LSM330DL multi-sensor module with six-degrees-of-freedom targets motion-sensing applications, including remote controls, black-box recorders, and GPS systems.
The multi-sensor module detects acceleration up to 16G and angular rate up to 2,000dps along the pitch, roll and yaw axes. The six-axis motion-sensing module can mount multiple components in one package to induce random alignment errors of the two sensors' reference axes.
Addressing energy efficiency on chip and at the system level, the motion-sensing module includes power-down and sleep modes and an embedded FIFO (first-in first-out) memory block, which removes the need for continuous communication between the module and the host processor, claims the company. The multi-sensor can operate at 2.4 to 3.6V.
The company's gyro-accelerometer six-axis combo chip is suitable for intuitive user interfaces in pointers and remotes, motion monitoring in black-box recorders, dead-reckoning and map-matching in navigation systems, and smart power-saving and free-fall detection in portable electronics. The multi-sensor module is pin-to-pin and software-compatible with the recently announced five-degrees-of-freedom LSM320DL module.
