PIN FUNCTION DESCRIPTION

Pin No.

Symbol

Pin Name

Description

 

 

 

 

6

DIN

Data input

Inputs serial data at rising edge of shift clock, starting from lower

 

 

 

bit.

 

 

 

 

5

DOUT

Data output

Outputs serial data at falling edge of shift clock, starting from

 

 

 

lower bit. This is N-ch open-drain output pin.

 

 

 

 

9

STB

Strobe

Initializes serial interface at rising or falling edge to make

 

 

 

Pd16312 waiting for reception of command. Data input after

 

 

 

STB has fallen is processed as command. While command data

 

 

 

is processed, current processing is stopped, and serial interface

 

 

 

is initialized. While STB is high, CLK is ignored.

 

 

 

 

8

CLK

Clock input

Reads serial data at rising edge, and outputs data at falling edge.

 

 

 

 

44

OSC

Oscillator pin

Connect resistor for determining oscillation frequency to this pin.

 

 

 

 

15 to 20

Seg1/KS1 to

High-voltage output

Segment output pins (Dual function as key source)

 

Seg6 /KS6

 

 

 

 

 

 

37 To32

Grid1 to Grid6

High-voltage output (grid)

Grid output pins

 

 

 

 

26,28 to 31

Seg12/Grid11 to

High-voltage output

These pins are selectable for segment or grid output.

 

Seg16/Grid7

(segment/grid)

 

 

 

 

 

42 to 39

LED1 to LED5

LED output

CMOS output. +20 mA max.

 

 

 

 

10 to 13

Key1 to Key4

Key data input

Data input to these pins is latched at end of display cycle.

 

 

 

 

1 to 4

SW1 to SW4

Switch input

These pins constitute 4-bit general-purpose input port.

 

 

 

 

14, 38

VDD

Logic power

± 10 %

 

 

 

 

7, 43

VSS

Logic ground

Connect this pin to GND of system.

 

 

 

 

27

VEE

Pull-down level

VDD − 35 V max.

 

 

 

 

21 to 25

Seg7 to Seg11

High-voltage output

Segment output pins.

 

 

 

 

4-13
