Notes: 1. If the A/D converter is not used, do not leave the AV_CC, AV_SS, and V_REF pins open.
Connect AV_CC and V_REF to V_CC, and connect AV_SS to V_SS.
2. Current dissipation values are for V_IHmin = V_CC – 0.5 V and V_ILmax = 0.5 V with all output
pins unloaded and the on-chip pull-up transistors in the off state.
3. The values are for V_RAM ≤ V_CC < 2.7 V, V_IHmin = V_CC × 0.9, and V_ILmax = 0.3 V.
4. I_CC depends on V_CC and f as follows:
I_CCmax = 1.0 (mA) + 0.7 (mA/MHz · V) × V_CC × f [normal mode]
I_CCmax = 1.0 (mA) + 0.5 (mA/MHz · V) × V_CC × f [sleep mode]
