Fluorescent Display Tube Controller Driver

DESCRIPTION

FEATURES

The PT6321 is a dot matrix fluorescent display tube

controller driver IC which displays characters,

numerics and symbols. Dot matrix fluorescent display

tube drive signals are generated by serial data sent

from a microcontroller. A display system is easily

realized by internal ROM and RAM for character

display.

•

Logic power supply(V_DD): 3.3V 10% / 5.0V 10%

Fluorescent display tube drive power supply (V_DISP):

20V~60V

•

VFD driver output current (VFD driver output can

directly be connected to the fluorescent display tube.

No pull-down resistor is required.)

- Segment driver (SEG1 to SEG35): -5.0mA

(V_DISP=60V)

- Segment driver (AD1 to AD4): -10.0mA (V_DISP=60V)

- Grid driver (COM1 to COM24): -20.0mA (V_DISP=60V)

General output port output current

- Output driver (P1-4): 1.0mA (V_DD=3.3V 10%)

2.0mA (V_DD=5.0V±10%)

•

Content of display

- CGROM: 5x7 dots, 240 types (character data)

- CGRAM: 5x7 dots, 16 types (character data)

- ADRAM: 24 (display digit) x 4 bits (symbol data)

- DCRAM: 24 (display digit) x 8 bits (register for

character data display)

- General output port: 4 bits (static mode)

•

Display control function

- Display digit: 9 to 24 digits

- Display duty (contrast adjustment): 8 stages

- All lights ON/OFF

•

3 interfaces with microcontroller: DA, /CS, /CP(4

interfaces if /RESET is added)

1-byte instruction execution (excluding data write to

RAM)

Built-in oscillation circuit (external C and R)

80-pin plastic LQFP (LQFP80-P-1414-0.65-K)
