PIN NAME
PIN NO.
I/O
FUNCTION
V
EXT

I
This pin is the external power supply between 2.7 and 5.25 volt.
This pin should be decoupled to V
SS
with a 0.1
μ
F capacitor.
This is the output of the on-chip 3 volt regulator which supplies the
digital circuit of the chip. This pin should be decoupled to V
SS
with
a 0.1
μ
F ceramic capacitor. This pin cannot be used for powering
external loads.

I/O
This is the output of the on-chip 5 volt charge pump which supplies
the analog circuit. When V
EXT
= +5V
±
5%, V
DD
is an input and
should be connected to V
EXT
externally. Charge pump capacitor
C1+ and C1- should not be used and BR0[b2] must be written into
logic "1". In this case V
EXT
and V
DD
can share the same 0.1
μ
F
decoupling capacitor to V
SS
. When V
EXT
= 2.7 to 5.25 volt, V
DD
is
a 5 volt charge pump output and should not be connected to V
EXT
.
V
DD
should be decoupled to V
SS
with a 0.1
μ
F capacitor. This pin
cannot be used for powering external loads.
V
SS

I
This pin connects the analog and digital ground and is typically
connected to 0 volt.
