SC16312
VFD CONTROLLER/DRIVER OF 1/4 ~1/11 DUTY
DESCRIPTION
The SC16312 is a FIP (Fluorescent Indicator Panel, or Vacuum
Fluorescent Display) controller/driver, and it’s duty is 1/4 or 1/11. It
includes 11 segment output lines, 6 grid output lines, 5 segment/grid
output drive lines, a display memory, a control circuit, and a key scan
circuit. Serial data is input to the SC16312 through a three-line serial
interface. This FIP controller/driver is ideal as a peripheral device for a
single-chip microcomputer.

QFP-44-10x10-0.8
LQFP-44-10x10-0.8
* Multiple display modes
* Key scanning (6x4 matrix).
ORDERING INFORMATION
* Dimming circuit (eight steps).
* High-voltage output (VDD –35V max).

3. LED PORT
Data is written to the LED port with command, starting from the least port’s least significant bit. 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.

4. SW DATA
SW data is read with the read command, starting from the least significant bit. Bits 5 to 8 of the SW data are 0.

5. COMMANDS
Commands set the display mode and status of the FIP driver.
The first 1 byte input to the SC16312 through the DIN pin after the STB pin has fallen is regarded as a
command.
If STB is set high while commands/data are transmitted, serial communication is initialized, and the
commands/data being transmitted are invalid (however, the commands/data previously transmitted remain valid).
(1)Display mode setting commands
These commands initialize the SC16312 and select the number of segments and the number of grid (1/4 to
1/11 duty, 11 segments to 16 segments).
When these commands are executed, the display is forcibly turned off, and key scanning is also stopped. To
resume display, the display command “ON”must be executed. If the same mode is selected, however,
nothing happens.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
Persons at a work bench should be earthed via a wrist strap.
Equipment cases should be earthed.
All tools used during assembly, including soldering tools and solder baths, must be earthed.
MOS devices should be packed for dispatch in antistatic/conductive containers.
