In Flash mode it is possible to transmit and receive LIN messages on the LIN bus. The slew rate control
mechanism of the LIN bus signal is disabled. This allows higher data transmission rates, disregarding the EMC
limitations of the LIN network. The Flash mode is intended to be used during the ECU production for programming
the microcontroller via the LIN bus interface.
The TLE7269G can be set to Flash mode either from Normal Slope mode or from Low Slope mode (see
Flash mode is entered by setting the EN pin to “Low” for the time
the TxD1 pin with the timing
the TLE7269G back to its previous state, be that either Normal Slope mode or Low Slope mode. Finally to release
the data transmission it is required to set the TxD1 pin and the TxD2 pin to “High” for the time
The TLE7269G can be set from Flash mode directly to Sleep mode by switching the EN pin to “Low”. Setting the
pin EN to “High” again, the device will return to Flash mode.
