SC16313
VFD CONTROLLER / DRIVER
DESCRIPTION
SC16313 is a Vacuum Fluorescent Display (VFD) or Fluorescent
Indicator Panel (FIP) controller/driver that is driven on a 1/4 to 1/8 duty
factor. It consists of 8 segment output lines, 4 grid output lines, 4
segment/grid output lines, one display memory, control circuit, key
scan circuit. Serial data is input to SC16313 via a three-line serial
interface. This VFD driver is ideal as a peripheral device of a single-
chip microcomputer.

data/command being transmitted is considered invalid. (However, the data/command already transmitted
remains valid)
Command 1: display mode setting command
This command initializes the SC16313 and selects the number of segments and number of grids (4 to 8
grids, 12 to 8 segments).
When this command is executed, display is forcibly turned off, and key scanning is also stopped. To resume
display, a display ON command must be executed.
SC16313 provides 4 display mode settings as shown in the diagram below. The bits 4 to 6 (b3 to b5) are
ignored, bits 7 & 8 (b6 to b7) are given a value of “0”.
On power application, the 8-digit, 8-segment mode is selected.

Display Mode Settings:
000: 4 digits, 12 segments
001: 5 digits, 11 segments
010: 6 digits, 10 segments
011: 7 digits, 9 segments
100: 8 digits, 8 segments
Command 2: data setting command
This command sets data write or data read modes. The data setting command, the bits 6 and 5 (b5, b4) are
ignored, bit 8 and bit 7 (b7, b6) are given the value of “01”. Please refer to the diagram below.
On power application, the normal operation mode and address increment mode are set.

Data write & read mode settings:
00: write data to display memory
10: read key data
Address increment mode settings (display
memory):
0: increment address after data has been written
1: fixes address
Test mode settings:
0: normal operation mode
1: test mode
Command 3: address setting command
This command sets an address of the display memory. The address is considered valid if it has a value of
“00H”to “0FH”. If the address is set to 10H or higher, the data is ignored until a valid address is set.
On power application, the address is set to “00H”.
Please refer to the diagram below.
