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 micro-
controller. 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)
• Package options:
80-pin plastic QFP (QFP80-P-1414-0.65-K) (Product name: MSM9201-01GS-K)
80-pin plastic QFP (QFP80-P-1420-0.80-BK) (Product name: MSM9201-01GS-BK)
