3-axis electronic compass


Since smartphones and tablet-type devices become multifunctional, compact, and thinner, the mounting area of electronic devices used in these products have become extremely narrow.  As processing capacity improves, the demand for low power consumption is increasing.
In response to these new demands, Asahi Kasei Microdevices Corporation, (AKM), has launched the AK09917D.  This product is compatible with I3C, a high-speed communication protocol whose interface reduces system load achieving low power consumption.  In addition, while maintaining the high performance of the AK09915D, package size has been reduced to the same size as AKM’s AK09916C.

● I3C Interface support

Capable of 12.5MHz (max.) communication in SDR, (Single data rate), Mode.

● Except for the interface, the AK09917D has the same functions and characteristics as the AK09915D.
● Package size is 1.2mm x 0.8mm x 0.5mm, equal to the AK09916C
