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. Tested 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.
