5 ¥ 7 Dot Character ¥ 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
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.
FEATURES
• Logic power supply (V_DD)
• Fluorescent display tube drive power supply (V_DISP)
