2. Electrical Characteristics

2.1

Absolute Maximum Ratings

Note:

See the Total Operating Time (TOT) Utility located at http://www.renesas.com. This utility is provided for

educational and evaluation purposes only and is subject to the accompanying disclaimer.

Note 1. Ports P205, P206, P400, P401, and P407 are 5V-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 might cause malfunction and the abnormal current that passes in

the device at this time might cause degradation of internal elements.

Note 2. See section 2.2.1, Tj/Ta Definition.

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

1, Part Numbering

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 by a 4.7-µF capacitor. The capacitor must be placed close to the

pin.
