General Description
The HT16528 is a Vacuum Fluorescent Display, VFD
controller/driver with dot matrix VFD display. It consists
of 80 segment output lines and 24 grid output lines. It
can display up to 16C´2L, 20C´2L, 24C´2L.
The HT16528 has a character generator ROM which
stores up to 240´5´8 dot characters.
The HT16528 has serial/parallel interface. This VFD
controller/driver is ideal as an MCU peripheral device.
