SC16312(文件编号:S&CIC0208)
1/4 to 1/11 Duty VFD Controller
Features
Logic voltage:5V
High-voltage output:VDD-30Vmax
Multiple display (11-segment & 11-digit to 16-segment &4-digit)
6×4 matrix key scanning
8 steps dimmer circuit
4 LED output ports
4-bit general purpose input port
No external resistors necessary for driver output (provides PMOS open-drain and pull-low resistor
output)
Serial interface with MCU (CLK, CS, DI, DO)
Applications
Consumer products panel function control
Other similar application panel function control
Industrial measuring instrument panel unction control
General Description
SC16312 is a VFD (Vacuum Fluorescent Display) controller driver that is driven on a 1/4 to 1/11
duty factor. It consists of 11 segment output lines, 6 grid output lines, 5 segment/grid output drives,4 LED
output ports, a control circuit, a display memory, and a key scancircuit.
Serial data inputs to the SC16312 through a three-line serial interface. This VFD controller/driver is
ideal as a peripheral device for an MCU.

I/O Description
I 4-bit general purpose input port
O Output serial data at the falling edge of the shift cloBck, Starting
from low order bit. This is an NMOS open-drain Output pin.
Input serial data at the rising edge of the shift clock, starting from
I the low order bit.
Power supply, ground
I Reads serial data at the rising edge ,and outputs data at the Falling
edge.
Initializes serial interface at the rising or falling edge of the
SC16312. Then it waits to receive a command. Data input After
I CS has fallen is processed as a command. While command data is
processed, current processing is stopped, and the serial interface
is initialized. While CS is high, CLK is ignored.
Keying data input to these pins is latched at the end of the display
IA
cycle.
