NOTE FOR SUPPLYING POWER
(1) Timing of power supplying to AC pin
Fig. 18 Timing of power supplying to AC pin
PRECAUTION FOR USE
In order to avoid noise and latch-up, connect a bypass capacitor
(0.1µF) directly between the V
and V
34
Notes on noise and latch-up
The internal circuit of M35061-XXXSP/FP is reset when the level
of the auto clear input pin AC is “L”.
This pin is hysteresis input with the pull-up resistor. The timing
about power supplying of AC pin is shown in Figure 18.
After supplying the power (V
the tW time must be reserved for 1 ms or more.
Before starting input from the microcomputer, the waiting time
(tS) must be reserved for 200 ms after the supply voltage to the
AC pin becomes 0.8
