AS5600
12-Bit Programmable Contactless
Potentiometer
The AS5600 is an easy to program magnetic rotary position
sensor with a high-resolution 12-bit analog or PWM output. This
contactless system measures the absolute angle of a diametric
magnetized on-axis magnet. This AS5600 is designed for
contactless potentiometer applications and its robust design
eliminates the influence of any homogenous external stray
magnetic fields.
The industry-standard I²C interface supports simple user
programming of non-volatile parameters without requiring a
dedicated programmer.
By default the output represents a range from 0 to 360 degrees.
It is also possible to define a smaller range to the output by
programming a zero angle (start position) and a maximum
angle (stop position).
The AS5600 is also equipped with a smart low power mode
feature to automatically reduce the power consumption.
An input pin (DIR) selects the polarity of the output with regard
to rotation direction. If DIR is connected to ground, the output
value increases with clockwise rotation. If DIR is connected to
VDD, the output value increases with counterclockwise
rotation.

AS5600 Detailed Description
The AS5600 is a Hall-based rotary magnetic position sensor
using planar sensors that convert the magnetic field
component perpendicular to the surface of the chip into a
voltage.
The signals coming from the Hall sensors are first amplified and
filtered before being converted by the analog-to-digital
converter (ADC). The output of the ADC is processed by the
hardwired CORDIC block (Coordinate Rotation Digital
Computer) to compute the angle and magnitude of the
magnetic field vector. The intensity of the magnetic field is used
by the automatic gain control (AGC) to adjust the amplification
level to compensate for temperature and magnetic field
variations.
The angle value provided by the CORDIC algorithm is used by
the output stage. The user can choose between an analog
output and a PWM-encoded digital output. The former provides
an output voltage which represents the angle as a ratiometric
linear absolute value. The latter provides a digital output which
represents the angle as the pulse width.
The AS5600 is programmed through an industry-standard I²C
interface to write an on-chip non-volatile memory. This
interface can be used to program a zero angle (start position)
and a maximum angle (stop position) which maps the full
resolution of the output to a subset of the entire 0 to 360 degree
range.
IC Power Management
The AS5600 be powered from a 5.0V supply using the on-chip
LDO regulator, or it can be powered directly from a 3.3V supply.
The internal LDO is not intended to power other external ICs
and needs a 1 μF capacitor to ground, as shown in Figure 13.
In 3.3V operation, the VDD5V and VDD3V3 pins must be tied
together. VDD is the voltage level present at the VDD5V pin.

AS5600 − Detailed Description
I²C Interface
The AS5600 supports the 2-wire Fast-mode Plus I²C-slave
protocol in device mode, in compliance with the NXP
Semiconductors (formerly Philips Semiconductors)
specification UM10204. A device that sends data onto the bus
is a transmitter and a device receiving data is a receiver. The
device that controls the message is called a master. The devices
that are controlled by the master are called slaves. A master
device generates the serial clock (SCL), controls the bus access,
and generates the START and STOP conditions that control the
bus. The AS5600 always operates as a slave on the I²C bus.
Connections to the bus are made through the open-drain I/O
lines SDA and the input SCL. Clock stretching is not included.
The host MCU (master) initiates data transfers. The 7-bit slave
address of the AS5600 is 0x36 (0110110 in binary).
Supported Modes
Random/Sequential read
Byte/Page write
Automatic increment (ANGLE register)
Standard-mode

The SDA signal is the bidirectional data line. The SCL signal is
the clock generated by the I²C bus master to synchronize
sampling data from SDA. The maximum SCL frequency is 1 MHz.
Data is sampled on the rising edge of SCL.

2. Input filters on the SDA and SCL inputs suppress noise spikes of less than 50 ns.
3. I/O pins of Fast-mode and Fast-mode Plus devices must not load or drive the SDA and SCL lines if VDD is switched OFF.
4. Special-purpose devices such as multiplexers and switches may exceed this capacitance because they connect multiple paths

AS5600 Detailed Description
I²C Modes
Invalid Addresses
There are two addresses used to access an AS5600 register. The
first is the slave address used to select the AS5600. All I²C bus
transactions include a slave address. The slave address of the
AS5600 is 0x36 (0110110 in binary) The second address is a word
address sent in the first byte transferred in a write transaction.
The word address selects a register on the AS5600. The word
address is loaded into the address pointer on the AS5600.
During subsequent read transactions and subsequent bytes in
the write transaction, the address pointer provides the address
of the selected register. The address pointer is incremented
after each byte is transferred, except for certain read
transactions to special registers.
If the user sets the address pointer to an invalid word address,
the address byte is not acknowledged (the A bit is high).
Nevertheless, a read or write cycle is possible. The address
pointer is increased after each byte.
Reading
When reading from an invalid address, the AS5600 returns all
zeros in the data bytes. The address pointer is incremented after
each byte. Sequential reads over the whole address range are
possible including address overflow.
Automatic Increment of the Address Pointer for ANGLE,
RAW ANGLE and MAGNITUDE Registers
These are special registers which suppress the automatic
increment of the address pointer on reads, so a re-read of these
registers requires no I²C write command to reload the address
pointer. This special treatment of the pointer is effective only if
the address pointer is set to the high byte of the register.
Writing
A write to an invalid address is not acknowledged by the
AS5600, although the address pointer is incremented. When the
address pointer points to a valid address again, a successful
write accessed is acknowledged. Page write over the whole
address range is possible including address overflow.
Supported Bus Protocol
Data transfer may be initiated only when the bus is not busy.
During data transfer, the data line must remain stable whenever
SCL is high. Changes in the data line while SCL is high are
interpreted as START or STOP conditions.

Document Feedback [v1-06] 2018-Jun-20
AS5600 − Detailed Description
Accordingly, the following bus conditions have been defined:
Bus Not Busy
Both SDA and SCL remain high.
Start Data Transfer
A change in the state of SDA from high to low while SCL is high
defines the START condition.
Stop Data Transfer
A change in the state of SDA from low to high while SCL is high
defines the STOP condition.
Data Valid
The state of the data line represents valid data when, after a
START condition, SDA is stable for the duration of the high
phase of SCL. The data on SDA must be changed during the low
phase of SCL. There is one clock period per bit of data.
Each I²C bus transaction is initiated with a START condition and
terminated with a STOP condition. The number of data bytes
transferred between START and STOP conditions is not limited,
and is determined by the I²C bus master. The information is
transferred byte-wise and each receiver acknowledges with a
ninth bit.
Acknowledge
Each I²C slave device, when addressed, is obliged to generate
an acknowledge after the reception of each byte. The I²C bus
master device must generate an extra clock period for this
acknowledge bit.
A slave that acknowledges must pull down SDA during the
acknowledge clock period in such a way that SDA is stable low
during the high phase of the acknowledge clock period. Of
course, setup and hold times must be taken into account. A
master must signal an end of a read transaction by not
generating an acknowledge bit on the last byte that has been
clocked out of the slave. In this case, the slave must leave SDA
high to enable the master to generate the STOP condition.

AS5600 Detailed Description
Depending on the state of the R/W bit, two types of data transfer
are possible:
Data Transfer from a Master Transmitter to a Slave Receiver
The first byte transmitted by the master is the slave address,
followed by R/W = 0. Next follows a number of data bytes. The
slave returns an acknowledge bit after each received byte. If the
slave does not understand the command or data it sends a not
acknowledge (NACK). Data is transferred with the most
significant bit (MSB) first.
Data Transfer from a Slave Transmitter to a Master Receiver
The master transmits the first byte (the slave address). The slave
then returns an acknowledge bit, followed by the slave
transmitting a number of data bytes. The master returns an
acknowledge bit after all received bytes other than the last byte.
At the end of the last received byte, a NACK is returned. The
master generates all of the SCL clock periods and the START and
STOP conditions. A transfer is ended with a STOP condition or
with a repeated START condition. Because a repeated START
condition is also the beginning of the next serial transfer, the
bus is not released. Data is transferred with the most significant
bit (MSB) first.
AS5600 Slave Modes
Slave Receiver Mode (Write Mode)
Serial data and clock are received through SDA and SCL. Each
byte is followed by an acknowledge bit or by a not acknowledge
depending on whether the address-pointer selects a valid
address. START and STOP conditions are recognized as the
beginning and end of a bus transaction. The slave address byte
is the first byte received after the START condition. The 7-bit
AS5600 address is 0x36 (0110110 in binary).
The 7-bit slave address is followed by the direction bit (R/W),
which, for a write, is 0 (low). After receiving and decoding the
slave address byte the slave device drives an acknowledge on
SDA. After the AS5600 acknowledges the slave address and
write bit, the master transmits a register address (word address)
to the AS5600. This is loaded into the address pointer on the
AS5600. If the address is a valid readable address, the AS5600
answers by sending an acknowledge (A bit low). If the address
pointer selects an invalid address, a not acknowledge is sent (A
bit high). The master may then transmit zero or more bytes of
data. If the address pointer selects an invalid address, the
received data are not stored. The address pointer will increment
after each byte transferred whether or not the address is valid.
If the address-pointer reaches a valid position again, the
AS5600 answers with an acknowledge and stores the data. The
master generates a STOP condition to terminate the write
transaction.

AS5600 − Detailed Description
Figure 18:
Data Write (Slave Receiver Mode)
Slave Transmitter Mode (Read Mode)
The first byte is received and handled as in the slave receiver
mode. However, in this mode, the direction bit indicates that
the AS5600 will drive data on SDA. START and STOP conditions
are recognized as the beginning and end of a bus transaction.
The slave address byte is the first byte received after the master
generates a START condition. The slave address byte contains
the 7-bit AS5600 address. The 7-bit slave address is followed by
the direction bit (R/W), which, for a read, is 1 (high). After
receiving and decoding the slave address byte, the slave device
drives an acknowledge on the SDA line. The AS5600 then begins
to transmit data starting with the register address pointed to
by the address pointer. If the address pointer is not written
before the initiation of a read transaction, the first address that
is read is the last one stored in the address pointer. The AS5600
must receive a not acknowledge (NACK) to end a read
transaction.

AS5600 Register Description
ZPOS/MPOS/MANG Registers
These registers are used to configure the start position (ZPOS)
and a stop position (MPOS) or maximum angle (MANG) for a
narrower angular range. The angular range must be greater
than 18 degrees. In case of narrowed angular range, the
resolution is not scaled to narrowed range (e.g. 0° to
360°(full-turn) 4096dec; 0° to180°2048dec). To configure
the angular range, see Angle Programming.
CONF Register
The CONF register supports customizing the AS5600. Figure 22
shows the mapping of the CONF register.

Note(s):
1. Forced in Low Power Mode (LPM)
ANGLE/RAW ANGLE Register
The RAW ANGLE register contains the unscaled and unmodified
angle. The scaled output value is available in the ANGLE register.
Note(s): The ANGLE register has a 10-LSB hysteresis at the limit
of the 360 degree range to avoid discontinuity points or
toggling of the output within one rotation.

AS5600Register Description
STATUS Register
The STATUS register provides bits that indicate the current state
of the AS5600.
Figure 23:
STATUS Register
AGC Register
The AS5600 uses Automatic Gain Control in a closed loop to
compensate for variations of the magnetic field strength due
to changes of temperature, airgap between IC and magnet, and
magnet degradation. The AGC register indicates the gain. For
the most robust performance, the gain value should be in the
center of its range. The airgap of the physical system can be
adjusted to achieve this value.
In 5V operation, the AGC range is 0-255 counts. The AGC range
is reduced to 0-128 counts in 3.3V mode.
MAGNITUDE Register
The MAGNITUDE register indicates the magnitude value of the
internal CORDIC.
Non-Volatile Memory (OTP)
The non-volatile memory is used to permanently program the
configuration. To program the non-volatile memory, the I²C
interface is used (Option A, Option C). Alternatively, start and
stop positions can be programmed through the output pin
(Option B). The programming can be either performed in the
5V supply mode or in the 3.3V operation mode but using a
minimum supply voltage of 3.3V and a 10 μF capacitor at the
VDD3V3 pin to ground. This 10 μF capacitor is needed only
during the programming of the device. Two different
commands are used to permanently program the device:
Name State When Bit Is High
MH AGC minimum gain overflow, magnet too strong
ML AGC maximum gain overflow, magnet too weak

AS5600 Register Description
Burn_Angle Command (ZPOS, MPOS)
The host microcontroller can perform a permanent
programming of ZPOS and MPOS with a BURN_ANGLE
command. To perform a BURN_ANGLE command, write the
value 0x80 into register 0xFF. The BURN_ANGLE command can
be executed up to 3 times. ZMCO shows how many times ZPOS
and MPOS have been permanently written.
This command may only be executed if the presence of the
magnet is detected (MD = 1).
Burn_Setting Command (MANG, CONFIG)
The host microcontroller can perform a permanent writing of
MANG and CONFIG with a BURN_SETTING command. To
perform a BURN_SETTING command, write the value 0x40 into
register 0xFF.
MANG can be written only if ZPOS and MPOS have never been
permanently written (ZMCO = 00). The BURN_ SETTING
command can be performed only one time.
Angle Programming
For applications which do not use the full 0 to 360 degree
angular range, the output resolution can be enhanced by
programming the range which is actually used. In this case, the
full resolution of the output is automatically scaled to the
programmed angular range. The angular range must be greater
than 18 degrees.
The range is specified by programming a start position (ZPOS)
and either a stop position (MPOS) or the size of the angular
range (MANG).
The BURN_ANGLE command can be executed up to 3 times.

Output Stage
The OUTS bits in the CONF register are used to choose between
an analog ratiometric output (default) and a digital PWM
output. If PWM is selected, the DAC is powered down.
Without regard to which output is enabled, an external unit can

AS5600 Register Description
Analog Output Mode
By default, the AS5600 output stage is configured as analog
ratiometric output. The Digital to Analog Converter (DAC) has
12-bit resolution. In default mode, the lower reference voltage
for the DAC is GND, while the upper reference voltage is VDD.
The output voltage on the OUT pin is ratiometric between GND
and VDD.
The maximum angular range can be programmed from
18 degrees to 360 degrees. The default range is 360 degrees.
As shown below, if the range is 360 degrees, to avoid
discontinuity points exactly at the limit of the range, a 10-LSB
hysteresis is applied. This hysteresis suppresses toggling the
OUT pin when the magnet is close to zero or 360 degrees.
Figure 27:
Output Characteristic Over a 360° Full-Turn Revolution
The AS5600 supports programming both a zero angle as well
as the maximum angular range. As shown in Figure 28, reducing
the maximum angular range pushes the non-discontinuity
points to the edges, away from the 0 and θmax (where θmax is
the maximum angle) by λ, where λ= (360 - θmax)/2.

Figure 28:
Output Characteristic Over a Range Smaller Than 360°
If the maximum angular range is smaller than 360 degrees, the
DAC resolution is automatically reduced. If θmax is the maximum
angle, the number of steps N of the output signal OUT is:
N = (θmax/360) × 4096
The AS5600 also allows selecting the output dynamic
characteristics of the OUT signal with the OUTS bits in the CONF
register. By default (OUTS = 00), the output can cover the full
voltage range (0V to VDD), but a reduced range from 10% to
90% between GND and VDD may be programmed (OUTS = 01).

AS5600 Register Description
PWM Output Mode
The AS5600 output stage can be programmed in the OUTS bits
of the CONF register for a PWM-encoded digital output (OUTS
= 10). In this mode, the OUT pin provides a digital PWM signal.
The duty cycle of each pulse is proportional to the absolute
angle of the rotating magnet.
The PWM signal consists of a frame of 4351 PWM clock periods
as shown in Figure 30. This PWM frame is composed of the
following sections:
128 PWM clock periods high
4095 PWM clock periods data
128 PWM clock periods low
The angle is represented in the data part of the frame, and one
PWM clock period represents one 4096th of the full angular
range. The PWM frequency is programmed with the PWMF bits
in the CONF register.
Figure 30:

An angle of zero degrees is represented by 128 clock periods

AS5600Register Description
Step Response and Filter Settings
The AS5600 has a digital post-processing programmable filter
which can be set in fast or slow modes. The fast filter mode can
be enabled by setting a fast filter threshold in the FTH bits of
the CONF register.
If the fast filter is OFF, the step output response is controlled by
the slow linear filter. The step response of the slow filter is
programmable with the SF bits in the CONF register. Figure 32
shows the tradeoff between delay and noise for the different
SF bit settings.

variation is greater than the fast filter threshold, otherwise the
output response is determined only by the slow filter. The fast

AS5600 Register Description
Hysteresis
To avoid any toggling of the output when the magnet is not
moving, a 1 to 3 LSB hysteresis of the 12-bit resolution can be
enabled with the HYST bits in the CONF register.
Magnet Detection
As a safety and diagnostic feature, the AS5600 indicates the
absence of the magnet. If the measured magnet field strength
goes below the minimum specified level (Bz_ERROR), the
output is driven low, without regard to which output mode has
been selected (analog or PWM) and the MD bit in the STATUS
register is 0.
Low Power Modes
A digital state machine automatically manages the low power
modes to reduce the average current consumption. Three low
power modes are available and can be enabled with the PM bits
in the CONF register. Current consumption and polling times
are shown in Figure 6.
Watchdog Timer
The watchdog timer allows saving power by switching into
LMP3 if the angle stays within the watchdog threshold of 4 LSB
for at least one minute, as shown in Figure 36. The watchdog
function can be enabled with the WD bit in the CONF register.

1. Given parameter characteristics have to be fulfilled over operation temperature and product lifetime
Magnetic Requirements
The AS5600 requires the magnetic field component Bz
perpendicular to the sensitive area on the chip.
Along the circumference of the Hall element circle the magnetic
field Bz should be sine-shaped. The magnetic field gradient of
Bz along the radius of the circle should be in the linear range
of the magnet to eliminate displacement error by the
differential measurement principle.
Figure 40:
Magnetic Field Bz and Typical Airgap
The typical airgap is between 0.5 mm and 3 mm, and it depends
on the selected magnet. A larger and stronger magnet allows a
larger airgap. Using the AGC value as a guide, the optimal airgap
can be found by adjusting the distance between the magnet
and the AS5600 so that the AGC value is in the center of its
range. The maximum allowed displacement of the rotational
axis of the reference magnet from the center of the package is
0.25 mm when using a magnet with a diameter of 6mm.
