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
FEATURES
* CMOS Technology
* Low Power Consumption
* Key Scanning (8 x 2 matrix)
* Multiple Display Modes: (8 Segments, 8 Digits to 12 Segments,
4 Digits)
* 8-Step Dimming Circuitry
* Serial Interface for Clock, Data Input, Data Output, Strobe Pins
* No External Resistors Needed for Driver Outputs
* Available in 28-pin, SOP Package
