Electrical characteristics

5.1

Parameter conditions

Unless otherwise specified, all voltages are referenced to ground (GND).

5.1.1

Minimum and maximum values

Unless otherwise specified, the minimum and maximum values are guaranteed in the following standard

conditions:

•

Ambient temperature is TA = 25 °C

•

Supply voltage is VDD: 3.3 V

•

System clock frequency is 32 MHz (clock source HSI)

•

SMPS clock frequency is 4 MHz

Data based on characterization results, design simulation and/or technology characteristics are indicated in the

table footnotes and are not tested in production. Based on characterization, the minimum and maximum values

refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean ±3σ).

5.1.2

Typical values

Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V. They are given only as design

guidelines and are not tested.

Typical ADC accuracy values are determined by characterization of a batch of samples from a standard diffusion

lot over the full temperature range, where 95% of the devices have an error less than or equal to the value

indicated (mean ± 2σ).

5.1.3

Typical curves

Unless otherwise specified, all typical curves are only given as design guidelines and are not tested.

5.1.4

Loading capacitor

The loading conditions used for pin parameter measurement are shown in the figure below.
