Sensor integrated circuits having a single edge nibble transmission (sent) output

A sensor comprising:

• a single semiconductor die supporting:
• a sensing element to produce a sensing element signal;
• and
• a processor responsive to the sensing element signal to generate a first sensor output signal at a first sensor output and a second sensor output signal at a second sensor output, the first sensor output signal comprising a first Single Edge Nibble Transmission (SENT) frame and the second sensor output signal comprising a second SENT frame, wherein the first SENT frame and the second SENT frame include the same data.

A method for generating a Single Edge Nibble Transmission (SENT) output signal of a sensor, the method comprising:

• generating a sensing element signal indicative of a characteristic of a target with a sensing element;
• and
• processing the sensing element signal to generate the SENT output signal indicative of the characteristic, wherein processing comprises:
• indicating a status of at least one diagnostic indicator in a Status and Communication (SCN) nibble of the SENT output signal, wherein
• the SCN nibble comprises a bit 0 and a bit 1;
• and
• embedding in at least one of a plurality of data nibbles of the SENT output signal (a) a cyclic redundancy check (CRC) of the bit 0 and the bit 1 of the SCN nibble and the plurality of data nibbles and (b) a count indicative of a new frame, the CRC being at least a five bit value.
