Pad types

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

pins:

S = Slow(a)

M = Medium(a) (b)

F = Fast(a) (b)

I = Input only with analog feature(a)

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

X = Oscillator

connected between these pins and the nearest VSS_LV

pin.(1)

11, 23, 57

19, 32, 85

VSS_LV

1.2V decoupling pins. Decoupling capacitor must be

connected between these pins and the nearest VDD_LV

pin.(1)

10, 24, 58

18, 33, 86

VDD_BV

Internal regulator supply voltage

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.

All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium

(see the PCR[SRC] description in the device reference manual).
