ML9207-xx Datasheet | OKI Electric

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 - - - - : 3.3 V ±10% or 5.0 V ±10% Logic power supply (VDD) Fluorescent display tube drive power supply (VDISP) : 3.3 V ±10% or 5.0 V ±10% Fluorescent display tube drive power supply (VFL) : - 20 to - 60 V VFD driver output current (VFD driver output can be connected directly to the fluorescent display tube.
