4. Electrical Characteristics
4.1 Absolute Maximum Ratings
Stresses beyond the absolute maximum ratings listed in the table below may cause permanent damage to the
device. These are stress ratings only, and do not refer to the functional operation of the device.

When writing to eFuses, VDD3P3_CPU should not exceed 3.3 V.
3
When VDD_SPI is used to drive peripherals, VDD3P3_CPU should comply with the peripherals’ specifica-
tions. For more information, please refer to Table 16.
