Signal Description
8
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
μF or greater bypass
capacitor in order to bypass the core logic voltage regulator,
required for proper chip operation. For more information,
please refer to Section 5.2.
1
VPP
Input
VPP—This pin should be left unconnected as an open circuit
for normal functionality.
