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

PT6301 V1.0

• Logic power supply (V

• VFD tube drive power supply (V

• VFD driver output current

• Content of display

• Display control function

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

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

• Standby function

• Built-in CIG testing circuit

• Available in CIG package type

(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)

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

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

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 digit: 1 to 20 digits

- Display duty (brightness adjustment): 0/1024 to 960/1024 stages

- All lights ON/OFF

Inhibiting the oscillator circuit provides low power consumption.

Only one driver output is high: -5mA @ V

All the driver outputs are high: -350mA @ V
