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. Contact Renesas Electronics sales office for information on derating operation under Ta = +85°C to +105°C.

Derating is the systematic reduction of load for improved reliability.

Note 4. The upper limit of the operating temperature is 85°C or 105°C, depending on the product. For details, see section x.x. 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 with high frequency

characteristics between the VCC and VSS pins, between the AVCC0 and AVSS0 pins, and between the

VREFH0 and VREFL0 pins when VREFH0 is selected as the high potential reference voltage for the

ADC12. Place capacitors of the following value as close as possible to every power supply pin and use

the shortest and heaviest possible traces:

● VCC and VSS: about 0.1 µF

● AVCC0 and AVSS0: about 0.1 µF

● VREFH0 and VREFL0: about 0.1 µF

Also, connect capacitors as stabilization capacitance.

Connect the VCL pin to a VSS pin by a 4.7 µF capacitor. Connect the VCC_DCDC pin to a VSS_DCDC pin

by a 1.0 µF capacitor. Each capacitor must be placed close to the pin.

Note 1. Use AVCC0 and VCC under the following conditions:

AVCC0 = VCC

Note 2. When powering on the VCC and AVCC0 pins, power them on at the same time or the VCC pin first and then the AVCC0 pins.

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