General Description
The HT16523 device is a dot matrix Vacuum Fluorescent Display, VFD, controller/driver which displays characters, numerics and symbols. Dot matrix VFD driving signals are received via a 3-line serial interface driven by an externally connected microcontroller. The display data is stored in the internal ROM and RAM for character and symbol display.
