FEDL9205-02 ¡ Semiconductor FEDL9205-02 This version:ML9205-01 Sep. 2000 Previous version: Jun. 1999 ¡ Semiconductor ML9205-01 GENERAL DESCRIPTION 5 ¥ 7 Dot Character ¥ 16-Digit Display Controller/Driver with Character RAM The ML9205-01 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 (VDD) : 3.3 V± 10% or 5.0 V± 10% 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. No pull-down resistor is required.) · Segment driver (SEG1 to SEG35) : –5.0 mA (VFL= –60 V) · Segment driver (AD1 to AD4) : –10.0 mA (VFL= –60 V) · Grid driver (COM1 to COM24) : –50.0 mA (VFL= –60 V) General output port output current · Output driver (P1 to P4) : ± 1.0 mA (VDD = 3.3 V± 10%) ± 2.0 mA (VDD = 5.0 V± 10%) Content of display · CGROM 5 ¥ 7 dots : 240 types (character data) · CGRAM 5 ¥ 7 dots : 16 types (character data) · ADRAM 24 (display digit) ¥ 4 bits (symbol data) · DCRAM 24 (display digit) ¥ 8 bits (register for character data display) · General output port 4 bits (static operation) Display cont...
