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

- Output driver (P1 and P2)

: –6 mA (V_FL= V_DD–42 V)

: –15 mA (V_FL= V_DD–42 V)

: –30 mA (V_FL= V_DD–42 V)

: ±1 mA (V_DD= 3.3 V ±10%)

±2 mA (V_DD= 5.0 V ±10%)

• Content of display

- CGROM

- CGRAM

- ADRAM

- DCRAM

5 × 7 dots

: 248 types (character data)

: 8 types (character data)

16 (display digit) × 2 bits (symbol data)

16 (display digit) × 8 bits (register for character data display)

- General output port

• Display control function

- Display digit

2 bits (static operation)

: 9 to 16 digits

- Display duty (contrast adjustment)

- All lights ON/OFFs

: 8 stages

• 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)
