Power supply voltage condition (*9)
*9: See below for the conditions relating to power supply voltages. The recommended operating conditions and all the
electrical characteristics are specified within these ranges. Operation outside the ranges below may fail to satisfy
the electrical characteristics or may cause an operation error.

Make sure that the V
DDCORE
power supply voltage is lower than the V
DDIO
power supply voltage. Note that the
difference between V
DDIO
and V
DDCORE
is not the same owing to the conditions (a) and (b) above.
Examples of use: Example 1 V
DDIO
= 3.0 V, V
DDCORE
= 2.5 V Example 2 V
DDIO
= 2.4 V, V
DDCORE
= 2.4 V
