22 / 35 page  Rev. 1.10 �� of �5 ���i� 1�� �01� ��-bit �RM Co�tex™-M� MCU HT��F1�51/51B/5�/5� 4 Electrical Characteristics Absolute Maximum Ratings The following table shows the absolute maximum ratings of the device. These are stress ratings only. Stresses beyond absolute maximum ratings may cause permanent damage to the device. Note that the device is not guaranteed to operate properly at the maximum ratings. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability. Table 3.
