6.2 DC Characteristics
All characteristics are specified at VDD = 3.3 volts and VSS = 0 volts over an operating temperature of 0° C to
+70° C for all frequencies of operation. The current consumption figures relate to typical conditions at 2.5 V core,
3.3V I/O, 18.432 MHz operation with the PLL enabled.

Notes: 1. The leakage value given assumes that the pin is configured as an input pin but is not currently being driven. An
input pin not driven will have a maximum leakage of 1 µA. When the pin is driven, there will be no leakage.
2. Assumes buffer has no pull-up or pull-down resistors.
3. The leakage value given assumes that the pin is configured as an output pin but is not currently being
driven. An output pin not driven will have leakage between 25 µA and 100 µA. When the pin is driven,
there will be no leakage. Note that this applies to all output pins and all I/O pins configured as outputs.
