ML9208-xx
5 × 7 Dot Character × 16-Digit Display Controller/Driver with Character RAM
GENERAL DESCRIPTION
The ML9208-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.
FEATURES
• Logic power supply and vacuum fluorescent display tube drive power supply (V_DD)
: 3.3 V ±10% or 5.0 V ±10%
• Fluorescent display tube drive power supply (V_FL) : V_DD –20 V to V_DD –42 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)
- Segment driver (AD1 and AD2)
- Grid driver (COM1 to COM16)
• General output port output current
: –6 mA (V_FL = V_DD –42 V)
: –15 mA (V_FL = V_DD –42 V)
: –30 mA (V_FL = V_DD –42 V)
- Output driver (P1 and P2)
• Content of display
: ±1 mA (V_DD = 3.3 V ±10%)
±2 mA (V_DD = 5.0 V ±10%)
- 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/OFFs
• 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)
• Package options:
64-pin plastic QFP (QFP64-P-1414-0.80-BK) (ML9208-xxGA)
64-pin plastic SSOP (SSOP64-P-525-0.80-K) (ML9208-xxMB)
