SAM7SE512/256/32 Summary
5.
Power Considerations
5.1
Power Supplies
The SAM7SE512/256/32 has six types of power supply pins and integrates a voltage regulator,
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.
VDDOUT pin. It is the output of the 1.8V voltage regulator.
VDDIO pin. It powers the I/O lines; two voltage ranges are supported:
– from 3.0V to 3.6V, 3.3V nominal
– or from 1.65V to 1.95V, 1.8V nominal.
VDDFLASH pin. It powers the USB transceivers and a part of the Flash. It 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.
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.
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 SAM7SE512/256/32 has a static current of less than 60 A on VDDCORE at 25°C, includ-
ing the RC oscillator, the voltage regulator and the power-on reset when the brownout detector
is deactivated. Activating the brownout detector adds 20 A static current.
The dynamic power consumption on VDDCORE is less than 80 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 SAM7SE512/256/32 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 20 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.
