2. Electrical Characteristics

2.2

Recommended Operating Conditions

Note 1. Comply with the following potential condition: VCC = AVCC0 = AVCC1 = VCC_USB

Note 2. The low CL crystal unit cannot be used when the VBATT voltage is less than 2.0 V.

Note 3. For details, refer to section 56.6.11, Voltage Range of Analog Power Supply Pins in the User’s Manual: Hardware.

Note 4. P07, P11 to P17, P20, P21, P30 to P33, P67, and PC0 to PC3 are 5 V tolerant.

Note 5. For P30 to P32, input as follows when the VBATT power supply is selected.

Vin Min. = –0.3, Max. = VBATT + 0.3 (VBATT = 1.62 to 3.6 V)

Note 1. Use a multilayer ceramic capacitor with a nominal capacitance of 0.22 µF, for which the sum of the capacitance tolerance and

change in the capacitance under the usage conditions will be no greater than ±30%.
