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

AI

Positive Supply Voltage.

3

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

AI:

Analogue Input

DO: Digital Output

OTP: One Time Programmable

MSB: Most Significant Bit

LSB: Least Significant Bit

Note: The pins 5 and 6 must not be connected!
