2.2 Description of Pin Functions
2.2.1 SDA
This is a serial data I/O pin for serial interface (N-ch open-drain).
2.2.2 SCL
This is a serial clock input pin for serial interface (N-ch open-drain).
2.2.3 S0 to S35, S36 to S39
Note
These pins are the segment signal output pins for the LCD controller/driver.
Note
64-pin product only.
2.2.4 COM0 to COM3
These pins are the common signal output pins for the LCD controller/driver.
2.2.5 LV
DD
This is the positive power supply pin for the LCD controller/driver.
2.2.6 LV
SS
This is the ground potential pin for the LCD controller/driver.
2.2.7 V
LC0
to V
LC2
These pins are the power supply voltage pins for driving the LCD.
2.2.8 CAPH, CAPL
These pins are the capacitor connection pins for driving the LCD.
2.2.9 RESET
This is the active-low system reset input pin.
2.2.10 LCLK
This is the system clock input pin.
The internal pull-down resistor is connected during low-level input to RESET pin.
