ML9207-xx Description
The ML9207-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.
