GENERAL DESCRIPTION
The MSM9201-01 is a dot matrix fluorescent display tube controller driver IC which displays characters, numerics and symbols.
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%)
