Go micro with new Bosch MEMS accelerometers from Mouser

Mouser Electronics is stocking the new BMA530 and BMA580 accelerometers from Bosch. The BMA530 and BMA580 are the world’s smallest acceleration sensors for space-constrained applications like wearables and hearables.

The Bosch BMA530 and BMA580 accelerometers, available from Mouser, offer high performance in a small package for design engineers requiring easy implementation without detailed application knowledge. Built-in features enable the BMA530 to track motion activities with a step counter, particularly suitable for wearables. The BMA580 targets hearables with voice activity detection that featured bone conduction. Typically, microphones consume a lot of power in hearables because they needed to be ‘always-on’ to listen for voice activity. However, bone conduction detects the vibration of the user’s voice to wake the device from sleep, increasing power savings in a miniature sensor size.

Compared to Bosch’s previous generation accelerometers, the BMA530 and BMA580 have a 76% smaller footprint (down from 0.95 to 0.55mm) in an innovative Wafer Level Chip Scale Package (WLCSP), making them easy to place on a PCB and integrate into portable products. They offer a flexible set of connectivity options, including an I3C interface.

The BMA530 and BMA580 accelerometers are supported by the BMA530 and BMA580 shuttle boards, available for order from Mouser. The shuttle boards, when used in conjunction with the Bosch Application board, which are also available to order, provide an example application circuit, allowing rapid prototyping when incorporated into existing designs.
