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)
