The allowed range of fOSC is 2MHz to 8MHz. If fOSC is
set too high, the internal oscillator can stop working. An
internal fail-safe circuit monitors the multiplex clock and
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 flickers. A flickering display
is a good indication that there is a problem with the
multiplex clock.
Power Supplies
The MAX6850 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 MAX6850 is driving high current from any of
the general-purpose output ports.
