ML9286-xx
Vacuum fluorescent display tube controller driver
FEDL9286-03
Jul. 9, 2013
GENERAL DESCRIPTION
The ML9286-xx is a 5 7 dot matrix type vacuum fluorescent display (VFD) tube controller driver IC which
displays characters, numerics and symbols of a maximum of 20digits  1 line.
Dot matrix VFD 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)
 VFD tube drive power supply (V_DISP)
 VFD driver output current
: 3.0V to 3.6V or 4.5V to 5.5V
: 20V to 80V
(VFD driver output can be connected directly to the VFD tube. No pull-down resistor is required.)
• Segment driver (SEG1 to SEG35)
• Segment driver (AD1 to AD2)
• Grid driver (COM1 to COM20)
 Content of display
: –5 mA
: –10 mA
: –30 mA
(V_DISP = 80 V)
(V_DISP = 80 V)
(V_DISP = 80 V)
• CGROM
: 5  7 dots
240 types (character data)
• CGRAM
: 5  7 dots
16 types (character data)
• ADRAM
: 24 (display timing)  2 bits (symbol data)
• DCRAM
: 24 (display timing)  8 bits (register for character data display)
 Display control function
• Display digit
: 9 to 20 digits
• GCRAM (Grid control RAM)
: The display timing from T9 to T24 can be set.
Built-in multi grid function
• Display duty (brightness adjustment) : 256 stages
• All lights ON/OFF
 4 interfaces with micro-controller
: DA, CS, CP, RESET
 1-byte instruction execution (excluding data write to RAM and Display duty set)
 Built-in oscillation circuit
 Crystal oscillation or ceramic oscillation
 Package options
