ML9209-xx

Vacuum fluorescent display tube controller driver

GENERAL DESCRIPTION

The ML9209-xx is an alphanumeric type vacuum fluorescent display (VFD) tube controller driver IC which can

display alphanumeric characters, symbols, and bar charts.

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.

-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 driving power supply (V_DD

)

: 3.3 V±10% or 5.0 V±10%

• Vacuum fluorescent display tube driving 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 VFD tube. No pull-down resistor is required.)

• Segment driver (SEG1–16)

• Segment driver (AD1, 2)

• Grid driver (COM1–16)

• Content of display

• CGROM

: –6 mA (V_FL= V_DD– 42 V)

: –15 mA (V_FL= V_DD– 42 V)

: –30 mA (V_FL= V_DD– 42 V)

: 16 segments 240 types (character data)

: 16 segments 16 types (character data)

• CGRAM

• ADRAM

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

• DCRAM

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

• Display control function

• Display digits

: 1 to 16 digits

: 16 stages

• Display duty (brightness adjustment)

• All display lights ON/OFF

• Four interfaces with microcontroller:

DA, CS, CP, RESET

• Instruction executable with 1 byte (excluding data write for each RAM)

• Built-in oscillation circuit (resistor & capacitor connected externally)

• Package options:

44-pin plastic QFP (QFP44-P-910-0.80-2K) (ML9209-xxGA)
