GENERAL DESCRIPTION
The MSM9201-01 is a dot matrix fluorescent display tube controller driver IC which displays
characters, numerics and symbols.
Dot matrix fluorescent display tube drive signals are generated by serial data sent from a micro-
controller. A display system is easily realized by internal ROM and RAM for character display.
