No. of Pins Signal Name Signal Description
8 V
DD
Power—These pins provide power to the internal structures of the chip, and
should all be attached to V
DD.
1 V
DDA
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.

No. of Pins Signal Name Signal Description
7 V
SS
GND—These pins provide grounding for the internal structures of the chip, and
should all be attached to V
SS.
1 V
SSA
Analog Ground—This pin supplies an analog ground.
1 TCS TCS—This Schmitt pin is reserved for factory use and must be tied to V
SS
for
normal use. In block diagrams, this pin is considered an additional V
SS.

Signal Description
2 VCAPC Supply Supply VCAPC—Connect each pin to a 2.2μF 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 Input VPP—This pin should be left unconnected as an open circuit
for normal functionality.
