31.1 Absolute Maximum Ratings
Note 1. Satisfy the relationship of VDD ≥ VCCRF and VCCDDC upon power application.
Note 2. Must be 3.8 V or lower.
Note 3. This value is AC rating. Impression of DC voltage is prohibited to RFIP and RFOUT pins.
Note 4. Do not exceed AV
REF (+) + 0.3 V in case of A/D conversion target pin.
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.
Remark 1. Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port pins.
Remark 2. AV
REF (+): + side reference voltage of the A/D converter.
Remark 3. V
