5V Single Supply Mode
The AT32UC3C has several types of power supply pins:
•
•
•
•
•
•
•
•
•
See
For decoupling recommendations for the different power supplies, please refer to the schematic
checklist.
The AT32UC3C embeds two voltage regulators:
The AT32UC3C supports two power supply configurations.
In 5V single supply mode, the 1.8V internal regulator is connected to the 5V source (VDDIN_5
pin) and its output feeds VDDCORE.
• One 1.8V internal regulator that converts from VDDIN_5 to 1.8V. The regulator supplies the
• One 3.3V internal regulator that converts from VDDIN_5 to 3.3V. The regulator supplies the
• 5V single supply mode
• 3.3V single supply mode
VDDIO pins (VDDIO1, VDDIO2, VDDIO3): Power I/O lines. Two voltage ranges are available: 5V or
3.3V nominal. The VDDIO pins should be connected together.
VDDANA: Powers the Analog part of the device (Analog I/Os, ADC, ACs, DACs). 2 voltage ranges
available: 5V or 3.3V nominal.
VDDIN_5: Input voltage for the 1.8V and 3.3V regulators. Two Voltage ranges are available: 5V or
3.3V nominal.
VDDIN_33:
VDDCORE: Stabilization for the 1.8V voltage regulator, requires external capacitors.
GNDCORE: Ground pins for the voltage regulators and the core.
GNDANA: Ground pin for Analog part of the design
GNDPLL: Ground pin for the PLLs
GNDIO pins (GNDIO1, GNDIO2, GNDIO3): Ground pins for the I/O lines. The GNDIO pins should be
connected together.
output voltage on VDDCORE.
USB pads on VDDIN_33. If the USB is not used or if VDDIN_5 is within the 3V range, the
3.3V regulator can be disabled through the VREG33CTL field of the VREGCTRL SCIF
register.
– USB I/O power supply
– if the device is 3.3V powered: Input voltage, voltage is 3.3V nominal.
– if the device is 5V powered: stabilization for the 3.3V voltage regulator, requires external
