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 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%/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%)
