SC16315S
VFD CONTROLLER/DRIVER
DESCRIPTION
SC16315S is a Vacuum Fluorescent Display (VFD) Controller
driven on a 1/4 to 1/8 duty factor. It has eight segment output lines, 4
grid output lines, 4 segment/grid output drive lines, one display
memory, control circuit, key scan circuit, those above are all
incorporated into a single chip to build a highly reliable peripheral
device for a single chip micro computer. Serial data is fed to
SC16315S via a three-line serial interface. It is housed in a 28-pin,
SOP Package.
SOP-28-375-1.27

COMMAND 3: Address setting commands
Address Setting Commands are used to set the address of the display memory. The address is considered
valid if it has a value of “00H”to “1DH”. The data is ignored until a valid address is set if the address is set to 1EH
or higher. When power is turned ON, the address is set at “00H”.
Please refer to the diagram below.

Please refer to the diagram below. When the power is turned ON, a 1/16 pulse width is selected and the
displayed is turned OFF (the key scanning is stopped).
