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 < 4.5 V, V_IHmin = V_CC × 0.9, and V_ILmax = 0.3 V.
Conditions: V_CC = 2.7 V to 5.5 V, AV_CC = 2.7 V to 5.5 V, V_REF = 2.7 V to AV_CC,
V_SS = AV_SS = 0 V*, T_a = –20°C to +75°C (regular specifications),
