Notes: 1. If the A/D or D/A converter is not used, the AVCC, Vref, and AVSS pins should not be

open. Even if the A/D or D/A converter is not used, connect the AVCC and Vref pins to

VCC and supply 4.0 V to 5.5 V. In this case, Vref

≤ AVcc.

2. Current consumption values are for VIH min = VCC – 0.5 V and VIL max = 0.5 V, with all

output pins unloaded and the on-chip MOS pull-up transistors in the off state.

3. The values are for VRAM

≤ VCC < 4.0 V, VIH min = VCC × 0.9, and VIL max = 0.3 V.

4. ICC depends on VCC and f as follows:

ICC max. = 2.0 (mA) + 0.7 (mA/V)

× VCC + 1.4 (mA/MHz) × f + 0.20 (mA/(MHz⋅V)) × VCC

× f (normal operation)

ICC max. = 1.5 (mA) + 0.6 (mA/V)

× VCC + 1.1 (mA/MHz) × f + 0.15 (mA/(MHz⋅V)) × VCC

× f (sleep mode)
