Continuous Timer Mode (CTM) for “Cyclic Wake Timer”
Upon start of the “cyclic wake timer” in Cyclic Wake Mode the operating mode might be
changed to “SBC Active Mode” by the microcontroller, e.g. in order to transmit data via
the CAN or LIN transceiver. In this case the timer continues running with the selected
period started in Cyclic Wake Mode. This behavior guarantees the periodic generation
of a wake-up signal at the WKO pin, even in case of a mode switch. However, this
provides that the time spent in SBC Active Mode is not exceeding the selected period.
Should a time-out (end of selected period) occur in SBC Active Mode before the Cyclic
Wake Mode is re-entered, the SBC will generate an interrupt signal at its WKO pin if the
CTM feature is enabled via the respective SPI bit (see
When the CTM feature is set in the SPI, a wake-up event at the CAN bus in “SBC Active
CAN Sleep” mode or at the LIN bus in the “SBC Active LIN Sleep” mode results in
switching WKO “low” in addition to switching the RxD to “low”.

The dual low dropout voltage regulator integrated in the TLE 7263E is able to drive
external as well as internal loads, e.g. CAN-circuit supplied via
bus short circuit. Its output voltage tolerance is better than ±2%. The maximum output
current for external loads is limited to 150 mA (
150 mA (
voltage regulator outputs are protected against overload and overtemperature. The
thermal pre-warning flag might be used by the microcontroller to reduce the power
dissipation of the TLE 7263E by switching off functions of minor priority until the
temperature threshold of the thermal shutdown is reached.
An external reverse current protection is required at the pin
capacitor from being discharged by negative transients or low input voltage.
A capacitor of 10 μF at the supply voltage input
combination with the required reverse polarity diode this prevents the device from
detecting power down conditions in case of negative transients on the supply line.
Stability of the output voltage is guaranteed for output capacitors
nevertheless it is recommended to use capacitors
and therefore improve the reset behavior at input voltage transients.
