ML9208A-xx
FEDL9208A-02
Issue Date: Nov. 16, 2009
5 ï´ 7 Dot Character ï´ 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
The ML9208A-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.
