16-Digit Display Controller/Driver with Character RAM
The ML9205-01 is a dot matrix vacuum fluorescent display tube controller driver IC which
displays characters, numerics and symbols.
Dot matrix vacuum 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.
