Electrical characteristics

15.1

Parameter conditions

Unless otherwise specified, all voltages are referred to GND.

15.2

Minimum and maximum values

Unless otherwise specified the minimum and maximum values are guaranteed in the worst conditions of ambient

temperature, supply voltage and frequencies by tests in production on 100% of the devices with an ambient

temperature at Tc = 25°C.

15.3

Typical values

Unless otherwise specified, typical data are based on Tc = 25 °C, VCC=1.8 V, VCC_IO=1.8 V and VBAT=1.8 V.

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

15.4

Absolute maximum ratings

This product contains devices to protect the inputs against damage due to high static voltages. It is advisable to

take normal precautions to avoid application of any voltage higher than the specified maximum rated voltages.
