SENT Interface: A standardized, uni-directional digital protocol. The information is coded in nibbles with

different length. One nibble contains 4 bit of information. Beside the angle information also a status

information and a CRC is transmitted.

The SENT protocol is implemented according to the standard SAE J2716 JAN2010. The unit time UT is

configurable according to Table 4-9.

Two different sensor configurations are possible:

Single Secure Sensor:

The protocol consists of following nibbles

• A synchronization period (56UT)

• A status nibble of 12-27 UT

• 3 data nibbles of 12-27 UT, transmitting a 12bit angle value

• 2 nibbles with a 8bit rolling counter information

• 1 nibble as the inverted 1st data nibble

• A CRC nibble of 12-27 UT

• A pause pulse, this is optional and can be deactivated

• A short serial message, this is optional and can be deactivated

Standard Sensor:

The protocol consists of following nibbles

• A synchronization period (56UT)

• A status nibble of 12-27 UT

• 3 data nibbles of 12-27 UT, transmitting a 12bit angle value

• A CRC nibble of 12-27 UT

• A pause pulse, this is optional and can be deactivated

• A short serial message, this is optional and can be deactivated
