AS5030
8-Bit Programmable High Speed Magnetic Rotary Encoder
1 General Description
The AS5030 is a contactless magnetic rotary encoder for accurate
angular measurement over a full turn of 360°.
It is a system-on-chip, combining integrated Hall elements, analog
front end and digital signal processing in a single device.
To measure the angle, only a simple two-pole magnet, rotating over
the center of the chip is required.
The absolute angle measurement provides instant indication of the
magnet’s angular position with a resolution of 8 bit = 256 positions
per revolution. This digital data is available as a serial bit stream and
as a PWM signal.
In addition to the angle information, the strength of the magnetic field
is also available as a 6-bit code.
Data transmission can be configured for 1-wire (PWM), 2-wires
(CLK, DIO) or 3-wires (CLK, DIO, CS).
A software programmable (OTP) zero position simplifies assembly
as the zero position of the magnet does not need to be mechanically
aligned.
A Power Down Mode together with fast startup- and measurement
cycles allows for very low average power consumption and makes
the AS5030 also suitable for battery operated equipment.

5 Absolute Maximum Ratings
Stresses beyond those listed in Table 2 may cause permanent damage to the device. These are stress ratings only, and functional operation of
the device at these or any other conditions beyond those indicated in Electrical Characteristics on page 6 is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Datasheet - Detailed Description
7 Detailed Description
The benefits of AS5030 are as follows:
Complete system-on-chip, no calibration required
Flexible system solution provides absolute serial and PWM output
Ideal for applications in harsh environments due to magnetic sensing principle
High reliability due to non-contact sensing
Robust system, tolerant to horizontal misalignment, airgap variations, temperature variations and external magnetic fields

7.1 Connecting the AS5030
The following examples show various ways to connect the AS5030 to an external controller:
7.2 Serial 3-Wire R/W Connection
In this mode, the AS5030 is connected to the external controller via three signals:
Chip Select (CS), Clock (CLK) inputs and bi-directional DIO (Data In/Out) output.
The controller sends commands over the DIO pin at the beginning of each data transmission sequence, such as reading the angle or putting the
AS5030 in and out of the reduced power modes.
A pull-down resistor is not required.
C1 and C2 are hardware configuration inputs. C1 must always be connected to VSS, C2 selects 3-wire mode (C2 = low) or 2-wire mode (C2 =
high)
