5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input. When configured as a ADC input,
digital section of the pad is disabled and the pin is not 5 V tolerant.
5 V tolerant pad providing digital I/O with TTL levels and hysteresis and analog output function. When configured as the DAC output,
digital section of the pad is disabled.
Pad provides digital I/O and USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and
Low-speed mode only). This pad is not 5 V tolerant.
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad with TTL levels and hysteresis. Internal pull-up and pull-down resistors disabled.
5 V tolerant pad with TTL levels and hysteresis and internal pull-up resistor.
5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
Pad provides special analog functionality.

analog ground: 0 V reference. This should nominally be the same voltage as V
but should be isolated to minimize noise and error.
3.3 V supply voltage: This is the power supply voltage for the I/O ports.
3.3 V voltage regulator supply voltage: This is the supply voltage for the on-chip
voltage regulator only.
analog 3.3 V pad supply voltage: This should be nominally the same voltage as

not used.
ADC positive reference voltage: This should be nominally the same voltage as
V
as a reference for ADC and DAC. This pin should be tied to 3.3 V if the ADC and
DAC are not used.
ADC negative reference voltage: This should be nominally the same voltage as
V
a reference for ADC and DAC.
RTC pin power supply: 3.3 V on this pin supplies the power to the RTC
peripheral.
