RX111 Group 5. Electrical Characteristics
5. Electrical Characteristics
5.1 Absolute Maximum Ratings
Caution: Permanent damage to the MCU may result if absolute maximum ratings are exceeded.
To preclude any malfunctions due to noise interference, insert capacitors of high frequency characteristics between the VCC and
VSS pins, between the AVCC0 and AVSS0 pins, between the VCC_USB and VSS_USB pins, and between the VREFH0 and
VREFL0 pins. Place capacitors of about 0.1 μF as close as possible to every power supply pin and use the shortest and heaviest
possible traces. Also, connect capacitors as stabilization capacitance.
Connect the VCL pin to a VSS pin via a 4.7 µF capacitor. The capacitor must be placed close to the pin.
Note 1. Ports 16, 17, A6, and B0 are 5 V tolerant.
Do not input signals or an I/O pull-up power supply while the device is not powered. The current injection that results from input
of such a signal or I/O pull-up may cause malfunction and the abnormal current that passes in the device at this time may cause
degradation of internal elements.
Note 2. The upper limit of operating temperature is 85°C or 105°C, depending on the product. For details, refer to 1.2 List of Products.
Note 1. Set VCC and VCC_USB to the same potential. Also, set VSS, AVSS0, and VSS_USB to the same potential.
Note 2. AVCC0 and VCC can be set individually within the operating range. For details, 30.7.10 Voltage Range of Analog Power Supply
Pins.
