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 microcontroller. A display system is easily realized by internal ROM and RAM for character display.

FEATURES

? Logic power supply (VDD) : 3.3 V±10/5.0 V±10

? Fluorescent display tube drive power supply (VDISP) : 3.3 V±10/5.0 V±10

? Fluorescent display tube drive power supply (VFL) : –20 to –60 V

? VFD driver output current

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

- Segment driver (SEG1 to SEG35) : –5.0 mA (VFL=–60V)

- Segment driver (AD1 to AD8) : –10.0 mA (VFL=–60V)

- Grid driver (COM1 to COM16) : –20.0 mA (VFL=–60V)

? General output port output current

- Output driver (P1-4) : ±1.0 mA (VDD=3.3V±10)

±2.0 mA (VDD=5.0V±10)

? Content of display

- CGROM 5·7 dots, 240 types (character data)

- CGRAM 5·7 dots, 16 types (character data)

- ADRAM 24 (display digit) ·4 bits (symbol data)

- DCRAM 24 (display digit) ·8 bits (register for character data display)

- General output port 4 bits (static mode)

? Display control function

- Display digit : 9 to 24 digits

- Display duty (contrast adjustment) : 8 stages

- All lights ON/OFF

? 3 interfaces with microcontroller : DA, CS, CP (4 interfaces if RESET is added)

? 1-byte instruction execution (excluding data write to RAM)

? Built-in oscillation circuit (external C and R)
