Supply characteristics
Notes
1.
This defines requirements for the external Power-on reset circuit. The exact requirements can be relaxed depending
on the specific application. A hysteresis is required to overcome reset oscillations especially in battery operated
applications.
For these parameters, the recommended external components are specified which are supported by the internal
oscillator. This is not measured on a sample-by-sample basis.
