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 of ML9205-xx 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.
