MSM9200-xx
5 ¥ 7 Dot Character ¥ 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
The MSM9200-xx 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 microcontroller. A display system is easily realized by internal ROM and RAM for character
display.
The MSM9200-xx has low power consumption because it is munufactured in CMOS process
technology.
-01 and -02 are available as general codes.
Custom codes are provided if necessary.
FEATURES
• Logic power supply (V_DD)
