SC16315
VFD CONTROLLER/DRIVER
DESCRIPTION
The SC16315 is a FIP (Fluorescent Indicator Panel, or Vacuum
Fluorescent Display) controller/driver that is driven on a 1/4 or 1/12
duty factor. It has 16 segment outputs, 4 grid outputs, 8 segment/grid
outputs, a display memory, a control circuit, and a key scan circuit.
Serial data comes from a three-line serial interface. This FIP
controller/driver is ideal as a peripheral device for a single-chip
microcomputer.
FEATURES
QFP44-10 x10-0.8(S)
* Multiple display modes (16-segment & 12-dight to 24-segment &
