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.

Note 6. External VDD mode does not support in HLQFP package.

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