Note 1. Ports P204, P205, P303, P407 to P413, P511, P512, P514, P515 and P708 to P715 are 5 V tolerant.

Note 2. Connect VCC_DCDC to VCC.

Note 3. See section 2.2.1. Tj/Ta Definition.

Note 4. Contact a Renesas Electronics sales office for information on derating operation when Tj = +95 °C to +125 °C. Derating is the

systematic reduction of load for improved reliability.

Note 5. The lower and upper limit of operating junction temperature depend on the product.

Caution: Permanent damage to the MCU might result if absolute maximum ratings are exceeded.
