1. The typical values are given for VDD = 3.0 V and max values are given for VDD = 3.6 V, unless otherwise specified.

2. Guaranteed by characterization results, 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. Guaranteed by test in production.

7. 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.
