ML9207-xx - OKI electronic

ML9207-xx 5 x 7 Dot Character x 24-Digit Display Controller/Driver

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. The ML9207-xx has low power c.
