3/7

The parameters on which the consumption depends are as follows:

s

The MCU inserts a delay of 256 CPU cycles to stabilize the internal RC, during this time it

consumes some current.

For example at 3.6V, the details of the duration of different modes are as follows:

– MCU in Halt mode: 72.00 ms

– MCU in Run mode (delay period + capacitor discharge time) : 211.2 µs

Setup No.
