GENERAL DESCRIPTION
The ML9205-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 ML9205-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 customer's request.
