+5VDC power supply. Common to microprocessor power supply pin V
Ground
LCD driver supply voltages. The Set Power Control command can switch
the on-chip and external power supply modes of these pins.
When external mode selects, the voltage determined by LCD cell is
impedance-converted by a resistive divider or an operational amplifier for
application. Voltages should be the following relationship:
V
When master mode selects, these voltages are generated on the chip:
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 output
Voltage adjustment pin. Applies voltage between V
a resistive divider.
Data input/outputs. The 8-bit bidirectional data buses to be connected
to the standard 8-bit microprocessor data buses. When the serial
interface selects, D7 is serial data input (SI) and D6 is serial clock input
(SCL).
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.
Chip select input. Data input/output is enabled when -CS1 is LOW and
CS2 is HIGH.
• Read enable input. When interfacing to an 8080-series microprocessor
• When interfacing to an 6800-series microprocessor and when its R/W
• Write enable input. When interfacing to an 8080-series microprocessor,
• When interfacing to an 6800-series microprocessor,
and when its RD is LOW, the S1D15206 series data bus output is enabled.
Enable (E) is HIGH, the S1D15206 series R/W input is enabled.
WR is active LOW.
it will be read mode when R/W is HIGH and it will be write mode when
R/W is LOW.
