• Pin Function
Pin Name No. Description
DI N 7 Data input pin. Input serial data at rising edge of shift clock, starting from the low order bit.
V
EE
30 Pull-down level. V DD-35 V max.
V
SS
12, 44 Logic ground. Connect this pin to system G N D.
V
DD
13, 43 Logic power pin. 5 V ±10%
KEY1 to KEY2 10, 11 Key data input. Data input to these pins is latched at the end of the display cycle.
LED1 to LED4 1 - 4 LED output pin. CMOS output. +20mA max.
Seg17/Grid12
to Seg24/Grid5 31 - 3 8 High-voltage output (segment/grid). Segment or grid driving.
Grid1 to Grid4 39 - 42 High-voltage output (grid). Grid output pins.
Seg1/KS1
to Seg16/KS16 14 - 29 High-voltage output (segment). Segment output pins (Dual function as key source).
OSC 5 Oscillator pin. Determine the oscillation frequency by the resistor connecting this pin and G N D ( V SS).
CLK 8 Clock input pin. Reads serial data at the rising edge, and outputs data at the falling edge.
STB 9 Strobe pin. Initializes serial interface at the rising or falling edge of the SC16315. It then waits for reception of
a command. Data input after STB has fallen is processed as a command.
W hile command data is processed,
current processing is stopped, and the serial interface is initialized. W hile STB is high, CLK is ignored.
DOUT 6 Data output pin. Output serial data at the falling edge of the shift clock, starting from low order bit.
This is
N -ch open-drain output pin.
