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

specified.

Based on characterization, not tested in production, unless otherwise specified

LCD enabled with external VLCD, static duty, division ratio = 256, all pixels active, no LCD connected

LCD enabled with external VLCD, 1/8 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.

Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY)

with two 6.8pF loading capacitors.

Tested in production

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.
