Appendix A Electrical Characteristics
A.1.9 I/O Characteristics
This section describes the characteristics of all I/O pins except EXTAL, XTAL,XFC,TEST,VREGEN and
supply pins.
CAUTION
The internal pull up/pull down device speciï¬cation is different depending on
maskset.
Table A-6. 3.3-V I/O Characteristics
Conditions are 3.15 V < VDD35 < 3.6 V temperature from â40°C to +140°C, unless otherwise noted
