General Description
The MAX6852 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
MAX6852 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 gener-
ation of cathode bias and filament supplies and to pro-
vide up to five logic outputs, including a buzzer driver.
The MAX6852 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. The display intensity
can be adjusted by an internal 16-step digital bright-
ness control. The device also includes separate annun-
ciator and cursor control with automatic blinking, as
well as a low-power shutdown mode.
The MAX6852 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. The MAX6852 is
compatible with SPI and QSPI.
For a 2-wire interfaced version, refer to the MAX6853
data sheet.
