Description
Oscillator input pin
A resistor is connected to this pin to determine the
oscillation frequency.
Data input pin
This pin inputs serial data at the rising edge of the shift
clock (starting from the lower bit).
Clock input pin
This pin reads serial data at the rising edge.
Serial interface strobe pin
The data input after the STB has fallen is processed as
a command. When this pin is “HIGH”, CLK is ignored.
Power supply
Segment output pins (p-channel, open drain)
Segment output pin/Grid output pin (CMOS output)
Ground pin
Grid output pins (n-channel, open drain)
No connection
Pin No.
