FEDL9202-04 ¡ Semiconductor FEDL9202-04 This version: Sep. 2000 MSM9202-01 Previous version: Feb. 1999 ¡ Semiconductor MSM9202-01 GENERAL DESCRIPTION 5 ¥ 7 Dot Character ¥ 16-Digit Display Controller/Driver with Character RAM The MSM9202-01 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 and vacuum fluorescent display tube drive power supply (VDD) : 3.3 V± 10% or 5.0 V± 10% : –20 to –60 V Fluorescent display tube drive power supply (VFL) 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) : –6 mA (VFL=–60V) - Segment driver (AD1 and AD2) : –15 mA (VFL=–60V) - Grid driver (COM1 to COM16) : –30 mA (VFL=–60V) General output port output current - Output driver (P1 and P2) : ± 1 mA (VDD=3.3V± 10%) ± 2 mA (VDD=5.0V± 10%) Content of display - CGROM 5¥7 dots : 248 types (character data) - CGRAM 5¥7 dots : 8 types (character data) - ADRAM 16 (display digit) ¥2 bits (symbol data) - DCRAM 16 (display digit) ¥8 bits (register for character data display) - General output port 2 bits (static operation) Display control function - Display digit : 9 to 16 digits - D...
