FUNCTION
OSCI
38
I
Oscillator input pin. Connect to a 32.768 KHz crystal. An external
capacitor is needed. In RC mode an internal resistor must be
added in circuit between the OSCI and OSCO pins.
OSCO
37
O
Oscillator output pin with internal capacitor.
VDD
35
I
Positive power supply.
VDD1
46
I
For voltage level shift during data transceiver.
VSS
40
I
Negative power supply.
VLCD1,
VLCD2
51, 50
I
LCD voltage pins.
CN,
CP
54, 55
I
CP is the voltage control capacitor positive pin. CN is the voltage
control capacitor negative pin.
A 0.1
F capacitor should be connected between these two pins.
TEST1
TEST2
36, 29
I
Test pins with pull-low resistor. Not used.
RST
34
I
Chip reset input pin. Active low with internal pull-high resistor.
