FB
This pin is the feedback resistor input of the booster circuit. It is used to adjust the booster output voltage
level (Vcc). This pin can be left open when the converter is not used.
BGGND
This is a ground pin for analog circuits. It must be connected to external ground.
VB
This pin is the internal voltage reference of booster circuit. A stabilization capacitor, typ. 1uF, should be
connected to Vss. This pin can be left open when the converter is not used.
V
This is the most positive voltage supply pin of the chip. It is supplied either by external high voltage
source or internal booster
V
This pin is the input pin for the voltage output high level for COM signals. It can be supplied externally or
internally. When V

These pins are the driving voltages for OLED driving segment pins SA0-SA131, SB0-SB131 and SC0-
SC131 respectively. They can be supplied externally or internally generated by VP circuit. When internal
VP is used, V
I
This pin is the segment output current reference pin. I
A resistor should be connected between this pin and V
VSL
This is segment voltage reference pin. This pin should be left open.
VCL
This is common voltage reference pin. This pin should be connected to V
COM0-COM131
These pins provide the Common switch signals to the OLED panel. These pins are in high impedance
state when display is off.
