Wakeup time from Low power mode
The wakeup times given in the following table are measured with the MSI RC oscillator. The
clock source used to wake up the device depends on the current operating mode:
• Sleep mode: the clock source is the clock that was set before entering Sleep mode
• Stop mode: the clock source is the MSI oscillator in the range configured before
entering Stop mode
• Standby mode: the clock source is the MSI oscillator running at 2.1 MHz
1. The typical values are given for V
DD
= 3.0 V and max values are given for V
DD
= 3.6 V, unless otherwise
specified.
2. Based on characterization, not tested in production, unless otherwise specified
3. LCD enabled with external VLCD, static duty, division ratio = 256, all pixels active, no LCD connected
4. LCD enabled with external VLCD, 1/8 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD
connected.
5. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY)
with two 6.8pF loading capacitors.
6. When MSI = 64 kHz, the RMS current is measured over the first 15 µs following the wakeup event. For the
remaining time of the wakeup period, the current is similar to the Run mode current.
