Symbol
Type
Name and function
1
DIN/DOUT
IN/OUT
Output serial data at falling edge of the shift clock,
starting from lower bit. Input serial data is clocked in at
rising edge of the shift clock, starting from lower bit.
2CLK
IN
Reads serial data at rising edge, and outputs data at
falling edge.
3STB
IN
Initializes serial interface at rising or falling edge to
make STLED316S wait for reception of command.
Data input after the falling edge of STB are processed
as a command. While command data are processed,
current processing is stopped, and the serial interface
is initialized. While STB is high, instructions are
ignored.
4IRQ_N
OUT
Interrupt output (active low) to interrupt the MCU
when there is a key press
5
DIG1_LED
OUT
Single output LED used together with the 8 segments
to drive up to 8 discrete LEDs
6,7,8
DIG2, DIG3,
DIG4
OUT
Digit output pins.
9VCC
PWR
5.0 V ± 10% Core main supply voltage. Bypass to
GND through a 0.1 F capacitor as close to the pin as
possible.
10,11,12
DIG5, DIG6,
DIG7
OUT
Digit output pins.
