Description
Pin No.
Oscillator Input Pin
1
A resistor is connected to this pin to determine the oscillation frequency
Data Output Pin (N-Channel, Open-Drain)
2
This pin outputs serial data at the falling edge of the shift clock.
Data Input Pin
This pin inputs serial data at the rising edge of the shift clock (starting
3
from the lower bit)
Clock Input Pin This pin reads serial data at the rising edge and
4
outputs data at the falling edge.
Serial Interface Strobe Pin
The data input after the STB has fallen is processed as a command.
5
When this pin is “HIGH", CLK is ignored.
Key Data Input Pins
The data sent to these pins are latched at the end of the display
