Bosch has launched the world’s smallest (1.2 × 0.8 × 0.55mm3) MEMS accelerometers for wearables and hearables. Space is at a premium in hearables, smartwatches, and other portable consumer products, and all components must be as small as possible. At the same time, OEMs are demanding plug-and-play step-counters and other sensors with built-in features that enable easy implementation without detailed application knowledge.
To meet these challenges, Bosch Sensortec has announced the BMA530 and BMA580, the world’s smallest MEMS accelerometers. Both devices include built-in features making them easy to design with. BMA530 tracks activities with its step counter and is especially suitable for wearables, and BMA580 targets hearables with voice activity detection. Both devices offer multiple power modes and automatically switch between low- and high-power modes to extend battery life. They offer a flexible set of connectivity options, including an I3C interface.
