Aceinna has announced a triple-redundant, three-axis MEMS accelerometer and gyroscope sensor for automotive driver assistance, drones and robotics.

Called IMU383ZA, the 24 x 37 x 9.5mm module is factory-calibrated across -40 to +85°C.

“IMU383ZA is an improved pin-compatible version of our IMU381ZA,” according to the company. “It offers 1.3°/hr, 0.08°/√hr performance and a triple-redundant sensor architecture for reliability. Aceinna’s proprietary voting scheme will use only valid sensor data – any defective sensor output or errant data set will be ignored or de-rated in importance.”

An SPI bus is included for communication, and the module includes a bootloader for field upgrades.

As well as car ADAS, electronic stability control and lane keep assist, applications are foreseen in self-driving taxis, self-driving delivery vehicles and other autonomous vehicles in agriculture, construction and industry.
