4-Wire Interfaced, 5 ✕ 7 Matrix Vacuum-

Fluorescent Display Controller

General Description

Features

o High-Speed 26MHz SPI-/QSPI-/MICROWIRE™-

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.

Compatible Serial Interface

o 2.7V to 3.6V Operation

o Controls Up to 96 5 x 7 Matrix Characters

o One Digit and Two Digits per Grid and Universal

Displays Supported

o 16-Step Digital Brightness Control

o Built-In ASCII 104-Character Font

o 24 User-Definable Characters

o Up to Four Annunciators per Grid with Automatic

Blinking Control

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.

o Separate Cursor Control with Automatic Blinking

o Filament Drive Full-Bridge Waveform Synthesis

o Buzzer Tone Generator with Single-Ended or

Push-Pull Driver

o Up to Five General-Purpose Logic Outputs

o 9µA Low-Power Shutdown (Data Retained)

o 16-Pin QSOP Package

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™.
