Symbol Type

Decription

SEG1 to 37 O Output pins for segment signals for driving VF display tube.

GRID1 to 3

SEL

DATA-IN

CLOCK

O Output pins for grid signals for driving VF display tube.

The GRID3 output is not used when the universal VF display tube is used.

I When at a "L" level, this pin selects 1/3-duty VF display tube.

When at a "H" level (or when used in the open state), this pin selects universal

VF display tube.

I Pin for series data input from microprocessor.

Data is input to the shift register on the rising edge of the CLOCK signal.

I Serial clock input pin.

Data is input through the DATA-IN pin at the rising edge of the serial clock.

24

OSC0

I RC oscillator connecting pins.

Connect a resistor between the OSC1 and OSC0 pins and a capacitor between

23

OSC1

O the OSC0 pin and the ground.

26

CS

I Chip select input pin. Circuit operation is valid when this pin is at a "L" level.

47

VDD1

Power supply pins. When using these pins, connect each of them to the power
