I
LVTTL
Reset: Reset Pin (active low)
This pin should connect to ground through a 0.1
F filter capacitor and a 10k resistor to
VDD. In application it can also directly connect to one output pin from microcontroller (MCU).
AVDD

Power
AVDD: Analog Power Supply
This pin provides power supply to the analog part. This pin should connect to DVDD and be
decoupled with a 0.1
F capacitor.
DVDD

Power
DVDD: Digital Power Supply
This pin provides power supply to the digital part. It should be decoupled with a 10
F capac-
itor and a 0.1
F capacitor.

P
Power
VDD18: Digital Power Supply (1.8 V)
These two pins should be connected together and connected to ground through a 10
F
capacitor.

I
OSC
OSCI: External Crystal Input
OSCO: External Crystal Output
A 16.384 MHz crystal is connected between OSCI and OSCO. There are two on-chip capac-
itor, therefore no need of external capacitors.
