FUNCTIONAL DESCRIPTION
Pin Functional Description
V
DD
Power supply input pin
Connected to a 12V power supply
GND
Ground Pin
This pin is 0V level.
CLOCK
Serial clock input pin
CS
Chip select input pin
When "H" is input to this pin, interfacing with a MCU is available through the CLOCK and the
DATA pins.
Therefore, 2 signal lines of the CLOCK and the DATA can be shared with other peripherals.
DATA I/O (Input-output)
Serial data input-output pin
This pin inputs display data and outputs keyscan and A/D conversion data.
VK
Daylight/dark mode selection input pin
When "H" is input, the dark mode is selected and an output duty cycle is determined by analog
or PWM data input into the VD pin.
When "L" is input, the daylight mode is selected and the output duty cycle becomes about
100%.
VD
Analog/PWM dimming data input pin
Analog/PWM dimming mode selection will be done by an internal detection circuit automati-
cally.
V
REF
Reference voltage output pin for the A/D converter
