PT6301

5 x 7 Dot Character x 20-Digit x 2-Line

Display Controller/Driver with Character RAM

DESCRIPTION

The PT6301 is a 5 × 7 dot matrix type vacuum

fluorescent display tube controller driver IC which

displays characters, numerics and symbols of a

maximum of 20 digits × 2 lines. 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. PT6301 has low power

consumption since it is made by CMOS process

technology. Custom codes are provided on customer’s

request.

FEATURES

• Logic power supply (VDD): 3.3V±10% or

5.0V±10%

• VFD tube drive power supply (VDISP ): 30 to 60V

• VFD driver output current(VFD driver output can

be connected directly to the VFD tube. No

pull-down resistor is required.)

- Segment driver (SEGA1 to A35, SEGB1 to

B35)

Only one driver output is high: -5mA @

VDISP-4V (VDISP=50V, Tj=25℃)

All the driver outputs are high: -350mA @

VDISP-4V (VDISP=50V, Tj=25℃)

- Segment driver (ADA, ADB): -15mA @

VDISP-4V (VDISP=50V, Tj=25℃)

- Grid driver (COM1 to 20): -40mA @ VDISP-4V

(VDISP=50V, Tj=25℃)

• Content of display

SEGA1 to SEGA35 and ADA

- CGROM_A 5 × 7 dots: 240 types (character data)

- CGRAM_A 5 × 7 dots: 16 types (character data)

- ADRAM_A 20 (display digit) × 1 bit (symbol data;

can be used for a cursor.)

- DCRAM_A 20 (display digit) × 8 bits (register for

character data display)

SEGB1 to SEGB35 and ADB

- CGROM_B 5 × 7 dots: 240 types (character data)

- CGRAM_B 5 × 7 dots: 16 types (character data)

- ADRAM_B 20 (display digit) × 1 bit (symbol data;

can be used for a cursor.)

- DCRAM_B 20 (display digit) × 8 bits (register for

character data display)

• Display control function

- Display digit: 1 to 20 digits

- Display duty (brightness adjustment): 0/1024 to

960/1024 stages

- All lights ON/OFF

• 4 interfaces with microcontroller : DA, CS, CP, and

RESET

• Built-in oscillation circuit (external R & C)

• Standby function

Inhibiting the oscillator circuit provides low power

consumption.

• Built-in CIG testing circuit

• Available in CIG package type
