GENERAL DESCRIPTION
The MSM9202-01 is a dot matrix vacuum fluorescent display tube controller driver IC which displays characters, numerics and symbols.
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.

FEATURES
• Logic power supply and vacuum fluorescent display tube drive power supply (VDD) : 3.3 V±10% or 5.0 V±10%
• Fluorescent display tube drive power supply (VFL) : –20 to –60 V
• VFD driver output current (VFD driver output can be connected directly to the fluorescent display tube. No pull-down resistor is required.)
    - Segment driver (SEG1 to SEG35) : –6 mA (VFL=–60V)
    - Segment driver (AD1 and AD2) : –15 mA (VFL=–60V)
    - Grid driver (COM1 to COM16) : –30 mA (VFL=–60V)
• General output port output current
    - Output driver (P1 and P2) : ±1 mA (VDD=3.3V±10%) ±2 mA (VDD=5.0V±10%)
• Content of display
    - CGROM 5·7 dots : 248 types (character data)
    - CGRAM 5·7 dots : 8 types (character data)
    - ADRAM 16 (display digit) ·2 bits (symbol data)
    - DCRAM 16 (display digit) ·8 bits (register for character data display)
    - General output port 2 bits (static operation)
• Display control function
    - Display digit : 9 to 16 digits
    - Display duty (contrast adjustment) : 8 stages
    - All lights ON/OFF
• 3 interfaces with microcontroller : DA, CS, CP (4 interfaces when RESET is added)
• 1-byte instruction execution (excluding data write to RAM)
• Built-in oscillation circuit (external R and C)
