Detailed Description
Overview of the MAX6853
The MAX6853 VFD controller generates the multiplex
timing for the following VFD display types:
Multiplexed displays with one digit per grid, and up
to 48 grids (in 48/1 mode). Each grid can contain
one 5 x 7 matrix character, a DP segment, a cursor
segment, and four extra annunciator segments
(Figure 1).
Multiplexed displays with two digits per grid, and up
to 48 grids (in 96/2 mode). Each grid can contain
two 5 x 7 matrix characters, two DP segments, and
two cursor segments. No annunciator segments are
supported (Figure 2).
Each digit can have a 5 x 7 matrix character, a DP seg-
ment, a cursor segment, and (for one-digit-per-grid dis-
plays only) four annunciators (Figure 3).
The 5 x 7 matrix character segments are not controlled
directly, but use on-chip fonts that map the segments.
The fonts comprise an ASCII 104-character fixed-font
set, and 24 user-definable characters. The predefined
characters follow the Arial font, with the addition of the
following common symbols: ,
, , °, , ±, ↑, and ↓. The
24 user-definable characters are uploaded by the user
into on-chip RAM through the serial interface and are lost
when the device is powered down. As well as custom 5 x
7 characters, the user-definable fonts can control up to
35 custom segments, bar graphs, or graphics.
Annunciator segments have individual, independent
control, so any combination of annunciators can be lit.
Annunciators can be off, lit, or blink either in phase or
out of phase with the cursor. The blink-speed control is
software selectable to be one or two blinks per second
(OSC = 4MHz).
DP segments can be lit or off, but have no blink control.
A DP segment is set by the same command that writes
the digit’s 5 x 7 matrix character.
The cursor segment is controlled differently. A single
register selects one digit’s cursor from the entire dis-
play, and that can be lit either continuously or blinking.
All the other digits’ cursors are off.
The designations of DP, cursor, and annunciator are
interchangeable. For example, consider an application
requiring only one DP lit at a time, but the DP needs to
