FLD(VFD) CONTROLLER
RESET CIRCUIT
To reset the controller, the RESET pin should be held at a “L” level
for 2
μ
s or more. Then the RESET pin is returned to an “H” level (the
power source voltage should be between 4.0 V and 5.5 V, and X
IN
oscillation is stable), reset is released.
Make sure that the reset input voltage is 0.5 V or less for 4.0 V of
V
CC
.

CLOCK GENERATING CIRCUIT
Oscillating circuit is built up by connecting pins X
IN
and X
OUT
as short
as possible and connecting a capacitor between pins X
IN
(X
OUT
) and
V
SS
.
When supplying a clock externally, input it to X
IN
pin and leave X
OUT
pin open.
