16-Digit Display Controller/Driver with Character RAM
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 customer's request.
