ML9206-xx
5 ¥ 7 Dot Character ¥ 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
The ML9206-xx 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.
The ML9206-xx has low power consumption since it is made by CMOS process technology.
-01 is available as a general-purpose code.
Custom codes are provided on customer's request.
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 : 1 to 16 digits
- Display duty (brightness adjustment) : 256 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 and display duty set mode to RAM)
• Built-in oscillation circuit (external R and C)
• Package options:
64-pin plastic QFP (QFP64-P-1414-0.80-BK) (Product name : ML9206-xxGS-BK)
64-pin plastic SSOP (SSOP64-P-525-0.80-K) (Product name : ML9206-xxGS-K)
xx indicates the code number.
