Pin types
6.3.1
P
OWER SUPPLY PINS
There are 6 different power supply domains (see Fig.3):
Digital core circuit (2.5 V): V
DD3V1
/V
SS3V1
Digital periphery circuit (3.0 V): V
DD3V2
/V
SS3V2
and
V
DD3V3
/V
SS3V3
PLL circuits and crystal oscillator (2.5 V): V
DDPLL
and
V
SSPLL
Analog circuits (2.5 V): V
DDA
and V
SSA
.
All V
SS
pins must be connected to the same ground plane
on the Printed-Circuit Board (PCB). All 2.5 V V
DD
pins
must be connected to the same power supply. All V
DD
pins
have to be separately decoupled, according to Chapter 18.
