PIN NAME
PIN NO.
I/O
FUNCTION
V
DD
34
I
This pin is the digital power supply at 5 volt. This pin should be
decoupled to GNDD with a 0.1
μ
F capacitor.
This is the output of the on-chip 2.7 volt regulator which supplies
the digital circuit of the chip. This pin should be decoupled to
GNDA2 with a 0.1
μ
F ceramic capacitor. This pin cannot be used
for powering external loads.

I
This pin connects the digital ground and is typically connected to 0
volt.
VAA1
40
I
This pin is the first analog power supply at 5 volt. This pin should
be decoupled to GNDA1 with a 0.1
μ
F capacitor.
