Note when using external clock
In principle, when using external clock, supply a clock to the X0 pin and an opposite-phase clock signal to the
X1 pin simultaneously. However in this case, the STOP mode (oscillator stop mode) must not be used, because
the X1 pin stops with the “H” output in the STOP mode. At 12.5 MHz or less, the device can be used with the
clock signal supplied only to the X0 pin.
Note : The X1 pin must be designed to have a delay within 15 ns, at 10 MHz, from the signal to the X0 pin.
About C pin
MB91345 series has an internal regulator. A bypass condenser of 4.7
F or above should be connected to the
C pin for the regulator.
About AVCC pin
MB91345 series has an internal A/D converter. A condenser of approximately 0.1 F should be connected
between the AVCC pin and AVSS pin.
Treatment of NC pin and OPEN pin
The NC and OPEN pins should always be open.
