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

DD.
External Crystal Oscillator Input—This input should be connected to an
8MHz external crystal or ceramic resonator. For more information, please
refer to
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.
Table 2-3 Grounds
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
