The sensor supports a basic version of the Single Edge Nibble Transmission (SENT)
protocol defined by SAE. The main difference between the standard version and its
implementation in the TLE4998 is the usage of an open drain instead of a push-pull
output.

•
• A status nibble of 36-81 µs
• Three data nibbles of 36-81 µs (data packet 1 with a length of 108-243 µs)
• Three data nibbles of 36-81 µs (data packet 2 with a length of 108-243 µs)
• A CRC nibble of 36-81 µs
Figure 13
The CRC checksum calculation includes the status nibble and the data nibbles. This
leads to a minimum transfer time of 456 µs, and a maximum transfer time of 816 µs per
sample.
It is important to know that the sampling time (when values are taken for temperature
compensation) here is always defined as the beginning of the synchronization period;
during this period, the resulting data is always calculated from scratch.

unit time frame concept. A transfer consists of the following parts:A synchronization
period of 168 µs (in parallel, a new sample is calculated)
The single edge is defined by a 9-µs low pulse on the output, followed by the high
