2. Overview
AK8963 is 3-axis electronic compass IC with high sensitive Hall sensor technology.
Small package of AK8963 incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis,
Y-axis, and Z-axis, a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing the
signal from each sensor. Self test function is also incorporated. From its compact foot print and thin package
feature, it is suitable for map heading up purpose in GPS-equipped cell phone to realize pedestrian navigation
function.
AK8963 has the following features:
(1) Silicon monolithic Hall-effect magnetic sensor with magnetic concentrator realizes 3-axis magnetometer
on a silicon chip. Analog circuit, digital logic, power block and interface block are also integrated on a
chip.
(2) Wide dynamic measurement range and high resolution with lower current consumption.
Output data resolution:
14-bit (0.6 µT/LSB)
16-bit (0.15 µT/LSB)
Measurement range:
± 4900 µT
Average current at 8Hz repetition rate:
280µA typ.
(3) Digital serial interface
- I2C bus interface to control AK8963 functions and to read out the measured data by external CPU. A
dedicated power supply for I2C bus interface can work in low-voltage apply as low as 1.65V.
- 4-wire SPI is also supported. A dedicated power supply for SPI can work in low-voltage apply as low as
1.65V.
(4) DRDY pin and register inform to system that measurement is end and set of data in registers are ready to
be read.
(5) Device is worked by on-chip oscillator so no external clock source is necessary.
(6) Self test function with internal magnetic source to confirm magnetic sensor operation on end products.

6. Functional Explanation
6.1.
Power States
When VDD and VID are turned on from Vdd=OFF (0V) and Vid=OFF (0V), all registers in AK8963 are
initialized by POR circuit and AK8963 transits to Power-down mode.
All the states in the table below can be set, although the transition from state 2 to state 3 and the transition from
state 3 to state 2 are prohibited.

Power state
OFF (0V).
It doesn’t affect external interface. Digital input
pins other than SCL and SDA pin should be fixed
to “L”(0V).

OFF (0V).
It doesn’t affect external interface. Digital input
pins other than SCL and SDA pin should be fixed
to “L” (0V).
ON
Reset Functions
When the power state is ON, always keep Vid≤Vdd.
Power-on reset (POR) works until Vdd reaches to the operation effective voltage (about 1.4V: reference value
for design) on power-on sequence. After POR is deactivated, all registers are initialized and transits to power
down mode.
When Vdd=2.4 ~ 3.6V, POR circuit and VID monitor circuit are active. When Vid=0V, AK8963 is in reset
status and it consumes the current of reset state (IDD4).
AK8963 has four types of reset;
(1) Power on reset (POR)
When Vdd rise is detected, POR circuit operates, and AK8963 is reset.
(2) VID monitor
When Vid is turned OFF (0V), AK8963 is reset.
(3) Reset pin (RSTN)
AK8963 is reset by Reset pin. When Reset pin is not used, connect to VID.
(4) Soft reset
AK8963 is reset by setting SRST bit.
When AK8963 is reset, all registers are initialized and AK8963 transits to Power-down mode.

Operation Modes
AK8963 has following seven operation modes:
(1) Power-down mode
(2) Single measurement mode
(3) Continuous measurement mode 1
(4) Continuous measurement mode 2
(5) External trigger measurement mode
(6) Self-test mode
(7) Fuse ROM access mode
By setting CNTL1 register MODE[3:0] bits, the operation set for each mode is started.
A transition from one mode to another is shown below.
MODE[3:0]=“0001”
Power-down
mode
MODE[3:0]=“0000”
Single measurement mode
Sensor is measured for one time and data is output.
Transits to Power-down mode automatically after
measurement ended.
Transits automatically
MODE[3:0]=“0010”
MODE[3:0]=“0000”
MODE[3:0]=“0110”
MODE[3:0]=“0000”
MODE[3:0]=“0100”
MODE[3:0]=“0000”
MODE[3:0]=“1000
MODE[3:0]=“0000”
Continuous measurement mode 1
Sensor is measured periodically in 8Hz.
Transits to Power-down mode by writing
MODE[3:0]=“0000”.
Continuous measurement mode 2
Sensor is measured periodically in 100Hz.
Transits to Power-down mode by writing
MODE[3:0]=“0000”.
External trigger measurement mode
Sensor is measured for one time by external trigger.
Waits for next trigger after data is output. Transits to
Power-down mode by writing MODE[3:0]=“0000”.
Self-test mode
Sensor is self-tested and the result is output. Transits
to Power-down mode automatically.
Transits automatically
MODE[3:0]=“1111
MODE[3:0]=“0000”
Fuse ROM access mode
Turn on the circuit needed to read out Fuse ROM.
Transits to Power-down mode by writing
MODE[3:0]=“0000”.
Figure 6.1 Operation modes
When power is turned ON, AK8963 is in power-down mode. When a specified value is set to MODE[3:0],
AK8963 transits to the specified mode and starts operation. When user wants to change operation mode, transit
to power-down mode first and then transit to other modes. After power-down mode is set, at least 100µs(Twat)
is needed before setting another mode.
