Description

OSC

Oscillator Input Pin

I A resistor is connected to this pin to

determine the oscillation frequency

DOUT

Data Output Pin (N-Channel, Open-Drain)

O This pin outputs serial data at the

falling edge of the shift clock.

Data Input Pin

DIN

I This pin inputs serial data at the rising edge

of the shift clock (starting from the lower bit)

CLK

I

Clock Input Pin This pin reads serial data at the rising edge

and outputs data at the falling edge.

Serial Interface Strobe Pin

STB

I

The data input after the STB has fallen

is processed as a command. When this

pin is HIGH", CLK is ignored.

K1, K2

Key Data Input Pins

I The data sent to these pins are latched at the end

of the display cycle. (Internal Pull-Low Resistor)
