VDD
Power—These pins provide power to the internal structures of the chip, and should all be
attached to VDD.
1
VDDA
Analog Power—This pin is a dedicated power pin for the analog portion of the chip and
should be connected to a low noise 3.3V supply.

VSS
GND—These pins provide grounding for the internal structures of the chip, and should all
be attached to VSS.
1
VSSA
Analog Ground—This pin supplies an analog ground.
1
TCS
TCS—This Schmitt pin is reserved for factory use and must be tied to VSS for normal use.
In block diagrams, this pin is considered an additional VSS.

VCAPC
Supply
VCAPC—Connect each pin to a 2.2
μFor greater bypass capacitor in order
to bypass the core logic voltage regulator (required for proper chip
operation). For more information, refer to Section 5.2.

Input
External Crystal Oscillator Input—This input should be connected to an
8MHz external crystal or ceramic resonator. For more information, please
refer to Section 3.5.
Port B GPIO—This multiplexed pin is a General Purpose I/O (GPIO) pin that
can be programmed as an input or output pin. This I/O can be utilized when
using the on-chip relaxation oscillator so the EXTAL pin is not needed.
