3.3

Voltage supply pins

Voltage supply pins are used to provide power to the device. Three dedicated

VDD_LV/VSS_LV supply pairs are used for 1.2 V regulator stabilization.

3.4

Pad types

In the device the following types of pads are available for system pins and functional port

pins:

S = Slow(b)

M = Medium(b) (c)

F = Fast(b) (c)

I = Input only with analog feature(b)

J = Input/Output (‘S’ pad) with analog feature

X = Oscillator

A decoupling capacitor must be placed between each of the three VDD_LV/VSS_LV supply pairs to ensure stable voltage

(see the recommended operating conditions in the device datasheet for details).

See the I/O pad electrical characteristics in the device datasheet for details.
