detects a slow or nonworking multiplex clock. When a
slow or nonworking multiplex clock is detected, an
internal fail-safe oscillator generates a replacement
clock of about 200kHz. This backup clock ensures that
the VFD is not damaged by the multiplex operation halt-
ing inadvertently. The scan rate for 16 digits is about
15Hz in fail-safe mode, and the display flickers. A flick-
ering display is a good indication that there is a prob-
lem with the multiplex clock.
Power Supplies
The MAX6853 operates from a single 2.7V to 3.6V
power supply. Bypass the power supply to GND with a
0.1F capacitor as close to the device as possible. Add
a bulk capacitor (such as a low-cost electrolytic 1F to
22F) if the MAX6853 is driving high current from any of
the general-purpose output ports.

FUNCTION
0x05
0x00–0x7F
Read
Read 7-bit user-definable font data entry from current font address. MSB of the
register data is clear. Font address pointer is incremented after the read.
0x05
0x00–0x7F
Write
Write 7-bit user-definable font data entry to current font address. Font address
pointer is incremented after the write.
0x05
0x80–0xFF
Write
Write font address pointer with the register data.

FONT POINTER
ADDRESS
ACTION
0x80 to 0xF6
Valid range to set the font address pointer. Pointer autoincrements after a font data read or write, while pointer
address remains in this range.
0xF7
Further font data is ignored after a font data read or write to this pointer address.
0xF8 to 0xFF
Invalid range to set the font address pointer. Pointer is set to 0x80.
