LCD driver supply voltages. The voltage determined by LCD cell is
impedance-converted by a resistive driver or an operational amplifier
for application. Voltages should be the following relationship:
V
When the on-chip operating power circuit is on, the following voltages
are given to V
performed by the Set LCD Bias command. (The S1D15303 and S1D15304
are fixed to 1/5 bias.)
8-bit bi-directional data bus to be connected to the standard 8-bit or 16-bit
microprocessor data bus.
When the serial interface selects;
Control/display data flag input. It is connected to the LSB of micro-
processor address bus. When LOW, the data on D0 to D7 is control data.
When HIGH, the data on D0 to D7 is display data.
When RES is caused to go LOW, initialization is executed.
A reset operation is performed at the RES signal level.
Chip select input. Data input/output is enabled when -CS1 is LOW and
CS2 is HIGH. When chip select is non-active, D0 to D7 will be "HZ".
• When interfacing to an 8080 series microprocessor:
• When interfacing to a 6800 series microprocessor:
DC/DC voltage converter capacitor 1 positive connection
DC/DC voltage converter capacitor 1 negative connection
DC/DC voltage converter capacitor 2 positive connection
DC/DC voltage converter capacitor 2 negative connection
DC/DC voltage converter capacitor 1 negative connection
DC/DC voltage converter output
Voltage adjustment pin. Applies voltage between V
a resistive divider.
+5V power supply. Connect to microprocessor power supply pin V
Active LOW. This input connects the RD signal of the 8080 series
microprocessor. While this signal is LOW, the S1D15300 series data
bus output is enabled.
Active HIGH. This is used as an enable clock input pin of the 6800 series
microprocessor.
