Characteristic data
Power supplies
The power supply is divided into seven separate power groups: CORE, PLL, IO1, IO2, IO3, IO4 and FL. Each group has its
corresponding V
DD
and V
SS
supplies.
The groups may be powered independently with the following restrictions:
1. V
DDCORE
and V
DDPLL
must always be tied to the same common voltage.
2. V
DDIO1
, V
DDIO2
and V
DDIO4
power supplies must not be lower than V
DDCORE
.
3. V
DDIO3
and V
DDFL
must always be tied to the same common voltage and must not be lower than 2.6 V (2.7 V for 8 Mbit Flash
memory, see note below).
Further information about power supply restrictions can be found in the Static data section of this document.
