GENERAL DESCRIPTION
The ML9206-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 micro-controller. A display system is easily realized by internal ROM and RAM for character display.
The ML9206-xx has low power consumption since it is made by CMOS process technology.
-01 is available as a general-purpose code. Custom codes are provided on customers request.
FEATURES
