GENERAL DESCRIPTION
The ML9203-xx is a 5
× 7 dot matrix type vacuum fluorescent display tube controller driver IC which displays
characters, numerics and symbols of a maximum of 16 digits
× 2 lines.
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.
The ML9203-xx has low power consumption since it is made by CMOS process technology.
–01 is available as a general-purpose code.
Custom codes are provided on customer’s request.
FEATURES
Logic power supply (V
DD)
: 3.3 V±10% or 5.0 V±10%
VFD tube drive power supply (V
DISP ) : 20 to 60 V
VFD driver output current
(VFD driver output can be connected directly to the VFD tube. No pull-down resistor is required.)
Segment driver (SEGA1 to A35, SEGB1 to B35)
Only one driver output is high
: –5 mA (V
DISP = 60 V)
All the driver outputs are high
: –350 mA (V
DISP = 60 V)
Segment driver (ADA, ADB)
: –20 mA (V
DISP = 60 V)
Grid driver (COM1 to 16)
: –50 mA (V
DISP = 60 V)
