ML9208-xx
5 × 7 Dot Character × 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
www.DataSheet4U.com
The ML9208-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.
FEATURES
• Logic power supply and vacuum fluorescent display tube drive power supply (VDD) : 3.3 V ±10% or 5.0 V ±10%
• Fluorescent display tube drive power supply (VFL) : VDD –20 V to VDD –42 V • VFD driver output current
(VFD driver output can be connected directly to the fluorescent display tube. No pull-down resistor is
required.)
- Segment driver (SEG1 to SEG35) - Segment driver (AD1 and AD2) - Grid driver (COM1 to COM16) • General output port output.
