Reference power supply for the step-up voltage circuit for the liquid crystal drive.
Capacitor 1 positive connection pin for the voltage converter
Capacitor 1 negative connection pin for the voltage converter
Capacitor 2 positive connection pin for the voltage converter
Capacitor 2 negative connection pin for the voltage converter
Capacitor 3 positive connection pin for the voltage converter
Capacitor 4 positive connection pin for the voltage converter
Power supply shared with the MPU terminal V
Power supply, 0V terminal connected to the system GND
Externally input V
If an internal voltage regulator is used, V
Multi-level power supply for the liquid crystal drive. The voltage applied is determined
by the liquid crystal cell, and is changed through the use of a resistive voltage divider
or through changing the impedance using an Op. Amp. Voltage levels are
determined based on V
V
Master operation: When the power supply turns ON, the internal power supply
circuits generate the V
selected using the LCD bias set command.
DC/DC voltage converter input/output pin. Connect a capacitor between this terminal
and V
Output voltage regulator terminal. This is only enabled (IRS = “L”) when the V
voltage regulator internal resistor is not used.
When the V
floating.
8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data
bus. When chip select is inactive, D0 to D7 are set to high impedance.
When serial interface is selected (P/S = “L”), then D7 serves as the serial data input
terminal (SI) and D6 serves as the serial clock input terminal (SCL). At this time, D0
to D5 are set to high impedance.
