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.

The AS5030 Demoboard

The AS5030 demoboard measures the angle of a diametral magnet turning over the AS5030 sensor. It is

controlled by a built-in microcontroller and shows the result on the LCD display or on the PC GUI via the USB

interface.

The board is powered from the USB plug if it is connected to a PC, or from an external power supply on the DC

Jack (>7.5V) if the board works in stand alone mode without any PC. The angle and AGC values are displayed on

the LCD screen in both modes.

Dimensions of the demo board: 77mm x 84mm (3.03 x 3.30 inch).

... The U1 switch enables the bootloader mode of the microcontroller, if pressed during power up. In normal mode, pressing the switch makes the microcontroller writing the zero position value into the active AS5030. The connector U7 is used for ISP programming of the microcontroller only.
