Power Considerations
5.1
Power Supplies
The AT91SAM7XC512/256/128 has six types of power supply pins and integrates a voltage reg-
ulator, allowing the device to be supplied with only one voltage. The six power supply pin types
are:
VDDIN pin. It powers the voltage regulator and the ADC; voltage ranges from 3.0V to 3.6V,
3.3V nominal. In order to decrease current consumption, if the voltage regulator and the ADC
are not used, VDDIN, ADVREF,AD4, AD5, AD6 and AD7 should be connected to GND. In this
case, VDDOUT should be left unconnected.
VDDOUT pin. It is the output of the 1.8V voltage regulator.
VDDIO pin. It powers the I/O lines; voltage ranges from 3.0V to 3.6V, 3.3V nominal.
VDDFLASH pin. It powers the USB transceivers and a part of the Flash and is required for
the Flash to operate correctly; voltage ranges from 3.0V to 3.6V, 3.3V nominal.
VDDCORE pins. They power the logic of the device; voltage ranges from 1.65V to 1.95V,
1.8V typical. It can be connected to the VDDOUT pin with decoupling capacitor. VDDCORE
is required for the device, including its embedded Flash, to operate correctly.
VDDPLL pin. It powers the oscillator and the PLL. It can be connected directly to the
VDDOUT pin.
No separate ground pins are provided for the different power supplies. Only GND pins are pro-
vided and should be connected as shortly as possible to the system ground plane.
5.2
Power Consumption
The AT91SAM7XC512/256/128 has a static current of less than 60 A on VDDCORE at 25°C,
including the RC oscillator, the voltage regulator and the power-on reset when the brownout
detector is deactivated. Activating the brownout detector adds 28 A static current.
The dynamic power consumption on VDDCORE is less than 90 mA at full speed when running
out of the Flash. Under the same conditions, the power consumption on VDDFLASH does not
exceed 10 mA.
5.3
Voltage Regulator
The AT91SAM7XC512/256/128 embeds a voltage regulator that is managed by the System
Controller.
In Normal Mode, the voltage regulator consumes less than 100 A static current and draws 100
mA of output current.
The voltage regulator also has a Low-power Mode. In this mode, it consumes less than 25 A
static current and draws 1 mA of output current.
Adequate output supply decoupling is mandatory for VDDOUT to reduce ripple and avoid oscil-
lations. The best way to achieve this is to use two capacitors in parallel: one external 470 pF (or
1 nF) NPO capacitor should be connected between VDDOUT and GND as close to the chip as
possible. One external 2.2 F (or 3.3 F) X7R capacitor should be connected between VDDOUT
and GND.
