2-Wire Interfaced, 5

7 Matrix Vacuum-

Fluorescent Display Controller

General Description

The MAX6853 compact vacuum-fluorescent display

(VFD) controller provides microprocessors with the mul-

tiplex timing for 5 x 7 matrix VFD displays up to 96

characters and controls industry-standard, shift-regis-

ter, high-voltage grid/anode VFD tube drivers. The

device supports display tubes using either one or two

digits per grid, as well as universal displays. The

MAX6853 provides an internal crosspoint switch to

match any tube-driver shift-register grid/anode order,

and is compatible with both chip-in-glass and external

tube drivers. Hardware is included to simplify the gen-

eration of cathode bias and filament supplies and to pro-

vide up to five logic outputs, including a buzzer driver.

The MAX6853 includes an ASCII 104-character font,

multiplex scan circuitry, and static RAM that stores

digit, cursor, and annunciator data, as well as font data

for 24 user-definable characters. An internal 16-step

digital brightness control adjusts the display intensity.

The device also includes separate annunciator and cur-

sor control with automatic blinking, as well as a low-

power shutdown mode.

The MAX6853 provides timing to generate the PWM

waveforms to drive the tube filament from a DC supply.

The filament drive is synchronized to the display multi-

plexing to eliminate beat artifacts.

For an SPI™-compatible version, refer to the MAX6852

data sheet.
