RAM standby voltage VRAM 2.0 — — V
Notes: 1. Do not le ave the AVCC, AVref, and AVSS pins open even if the A/D converter is not used.
Even if the A/D converter is not used, apply a value in the range 2.0 V to 3.6 V to AVCC
and AVref pins by connection to the power supply (VCC), or some other method. Ensure
that AVref ≤ AVCC.
2. Current dissipation values are for VIH min = VCC – 0.2 V, VCCB – 0.2 V, and
VIL max = 0.2 V with all output pins unloaded and the on-chip pull-up MOSs in the off
state.
3. The values are for VRAM ≤ VCC < 3.0 V, VIH min = VCC– 0.2 V, VCCB – 0.2 V, and
VIL max = 0.2 V.
4. The port A characteristics depend on VCCB, and the other pins characteristics depend
on VCC.
5. For flash memory programming/erasure, the applicable range is VCC = 3.0 V to 3.6 V.

Conditions: VCC = 3.0 V to 3.6 V, VCCB = 3.0 V to 5.5 V, AVCC* = 3.0 V to 3.6 V,
AVref* = 3.0 V to AVCC, VSS = AVSS*1 = 0 V, Ta = –20 to +75°C

Note: * Do not leave th e AVCC, AVref, and AVSS pins open even if the A/D converter is not used.
Even if the A/D converter is not used, apply a value in the range 2.0 V to 3.6 V to AVCC
and AVref pins by connection to the power supply (VCC), or some other method. Ensure
that AVref ≤ AVCC.
