PIN DESCRIPTION

Pin Name

I/O

Description

LED1 to LED4

O

LED Output Pin

Oscillator Input Pin

OSC

I

A resistor is connected to this pin to determine the oscillation

frequency.

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

DOUT

O

This pin outputs serial data at the falling edge of the shift clock

(starting from the lower bit).

DIN

(Schmitt Trigger)

Data Input Pin

I

This pin inputs serial data at the rising edge of the shift clock

(starting from the lower bit).

CLK

(Schmitt Trigger)

Clock Input Pin

I

This pin reads serial data at the rising edge and outputs data at

the falling edge.

STB

(Schmitt Trigger)

Serial Interface Strobe Pin

I

The data input after the STB has fallen is processed as a

command. When this in is “HIGH”, CLK is ignored.

Key Data Input Pins

K1, K2

I

The data inputted to these pins is latched at the end of the

display cycle.
