POWER SUPPLY

Core supply 3 3 V Digital logic supply voltage

VDD#

Core supply +3.3 V. Digital logic supply voltage.

129

† Bold, italicized pin names indicate pin function after reset.

‡ GPIO − General-purpose input/output pin. All GPIOs come up as input after reset.

§ It is highly recommended that VCCA be isolated from the digital supply voltage (and VSSA from digital ground) to maintain the specified accuracy

and improve the noise immunity of the ADC.

¶ Only when all of the following conditions are met: EMU1/OFF is low, TRST is low, and EMU0 is high

# No power supply pin (VDD, VDDO, VSS, or VSSO) should be left unconnected. All power supply pins must be connected appropriately for proper

device operation.

LEGEND:

↑ − Internal pullup

↓ − Internal pulldown

(Typical active pullup/pulldown value is

±16 µA.)
