AS5020

Pin Description

Pin # Symbol Type Description

1

DATA DO DATA Output of the SSI.

If PD/CS=0, the measured angle data (6bit value) is serially

shifted out over this pin by the CLK, starting with the MSB. A

NVR Bit and a Parity bit are added. (NVR=1 indicates a Non-

Valid Range of the magnetic field.) Even Parity is given.

2

VDD

AI Positive Supply Voltage.

3

VSS

AI Negative Supply Voltage (GND).

4

PROG

DI PROGramming Input.

This pin is used to program the zero position into a non-volatile

memory (OTP). The programmed value is subtracted from the

actual measured angle.

5

N.C.

AI Not Connected during operation. This pin is used for testing

purposes.

6

N.C.

AI Not Connected during operation. This pin is used for testing

purposes.

7 PD/CS DI Power Down Input, Disable or Chip Select (active low).

PD/CS=0 activates the device and enables the measurement.

PD/CS=1 sets the device in power save mode and puts the

DATA pin in high impedance (highZ) state.

8

CLK

DI CLOCK Input of the SSI.

This pin is used to serially clock out the measured angle data at

Pin 7 (DATA).

DI: Digital Input

DO: Digital Output
