SENT bus - introduction SENT (Single Edge Nibble Transmission), SAE standard J2716, is a one way, point-to-point protocol for transmission of signal values from sensors to a controller. It is used mainly in automotive applications and enables reliable transmission of high-resolution data with lower cost than standards such as CAN, and higher bit rate than LIN. Data is transmitted in units of 4 bits (1 nibble), for which the time is measured between falling edges (single edge) of the modulated signal. Nibbles are assembled into message frames that typically contain two 12-bit data words although other options are also possible, such as 16 bits for signal 1 and 8 bits for signal 2. SENT data format is determined by what is best suited to the application. Once the format and data set have been selected, it is usually fixed in the design or configured with nonvolatile memory so that the data is continually transmitted on power up.
