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 (V_DD)
• Fluorescent display tube drive power supply (V_DISP)
• Fluorescent display tube drive power supply (V_FL)
• VFD driver output current
: 3.3 V±10%/5.0 V±10%

(VFD driver output can directly be connected to the fluorescent display tube. No pull-down
resistor is required.)
