General Description
The HT16525 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.
