Oki Electric Industry MSM9201-01
The MSM9201-01 is a dot matrix fluorescent display tube controller driver IC which displays characters, numerics and symbols.GENERAL DESCRIPTION
Dot matrix fluorescent display tube drive signals are generated by serial data sent from a microcontroller. A display system is easily realized by internal ROM and RAM for character display.FEATURES
● Logic power supply (VDD) : 3.3 V± 10%/5.0 V± 10%● Fluorescent display tube drive power supply (VDISP) : 3.3 V± 10%/5.0 V± 10%
● Fluorescent display tube drive power supply (VFL) : –20 to –60 V
● VFD driver output current (VFD driver output can directly be connected to the fluorescent display tube. No pull-down resistor is required.) - Segment driver (SEG1 to SEG35) : –5.0 mA (VFL=–60V) - Segment driver (AD1 to AD8) : –10.0 mA (VFL=–60V) - Grid driver (COM1 to COM16) : –20.0 mA (VFL=–60V)
● General output port output current - Output driver (P1-4) : ± 1.0 mA (VDD=3.3V± 10%) ± 2.0 mA (VDD=5.0V± 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 (d...
