Caution
Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions
that ensure that the absolute maximum ratings are not exceeded.
Note
Instantaneous input of a voltage in the range of
0.8 to VDD12 + 0.8 V is allowed as long as capacitive
coupling is implemented.

Notes 1.
This is the voltage that guarantees retention of data in the internal SRAM when the voltage drops during
normal operation.
2.
This is the voltage at which oscillation always starts after power-on.
3.
This is the voltage that guarantees oscillation when the voltage drops during normal operation.
