Bosch BMA400 3-axis Ultra-Low-Power Accelerometer
Bosch Sensortec BMA400 is a 12-bit triaxial accelerometer optimized for ultra-low-power applications such as wearables, hearables, and IoT motion-triggered devices. It combines an always-on auto-wakeup mode (~800 nA @ 25 Hz ODR), built-in step counter and activity recognition (walking/running/standing), orientation and tap/double-tap detection, and a 1 kB FIFO. Hosts can talk to it over I2C (Standard/Fast/HS up to 3.4 MHz) or SPI (3-wire or 4-wire, up to 10 MHz). Two configurable interrupt outputs (INT1, INT2) drive motion-triggered processors. This part is the bare 12-pin LGA chip (2.0 x 2.0 x 0.95 mm) — not a breakout — for use on custom PCBs.
