ML9207-xx

5 × 7 Dot Character × 24-Digit Display Controller/Driver with Character RAM

GENERAL 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.

The ML9207-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.

FEATURES

•

Logic power supply (V_DD

)
