Recommended Operating Conditions

Note 1. When powering on the VCC and AVCC0 pins, power them on at the same time or the VCC pin first and then the AVCC0 pin.

Note 2. When VCC < 2.4 V, normal operating mode functions of the CTSU are restricted. For details, refer to section 39, Capacitive

Touch Sensing Unit (CTSU2SLa) in the User’s Manual: Hardware.

Note 3. The upper limit of operating temperature is 85°C or 105°C, depending on the product. For details, refer to section 1.2, List of

Products.

Note 1. Use a multilayer ceramic capacitor with a nominal capacitance of 4.7 μF, for which the sum of the capacitance tolerance and

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