■ GENERAL DESCRIPTION
The NJU3426 is a VFD (Vacuum Fluorescent Display) controller/driver to dynamically drive up to 16 segments x 15 digits. It consists of display data RAM, an address counter, command registers, a serial interface and high voltage drivers. The direct control from the MPU and high voltage drivers of 45V make the NJU3426 well suited for various VFD displays.
