Electronic Compass

Ultra-compact package 3-axis Electronic Compass for Mobile Devices with I3C bus interface compliance

AK09919C

I3C bus interface compliance with FIFO 16 steps

AK09919C is upward compatible with AKM's previous product AK09918C.
It incorporates I3C bus interface and FIFO 16 steps as new features while maintaining AK09918C footprint and pin compatibility.

AK09919C is packaged in 4-pin WL-CSP with 0.4 mm ball-pitch. Size is 0.76 mm × 0.76 mm × 0.5 mm and 2 pins for power supply, 2 pins for I3C/I²C communication.
