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.

LED port
The LED port belongs to the CMOS output configuration.
Data is written to the LED port with the write command, starting from the least port’s least
significant bit. In out application (see application circuits). The user adopts an internal NMOS device to a
driver LED component by connecting VDD. When a bit of this port is 0, the corresponding LED lights;
when the bit is 1,the LED turns off. The data of bits 5 through 8 are ignored.
SW data
SC16312 provides an extra 4-bit general input port. The SW data is provided with available binary
code. The SW data is read with the read command. Starting from the least significant bit. Bits 5 through 8
of the SW data are 0.
Commands
Commands set the display mode and status of the VFD driver.
The first 1 byte input to the SC16312 through the DI pin after the CS pin has fallen, is regarded as a
command. If CS is set high while commands/data are transmitted. Serial communication is initialized,
and the commands/data being transmitted are not valid (however, the commands/data previously
transmitted remains valid).
• Display mode setting commands
These commands initialize the SC16312 and select the number of segments and the number of grids
(1/4~1/11 duty, 11 segments to 16 segments).
When these commands are executed, the display is forcibly turned off, and key scanning is selected,
nothing happens.
