Notes: 1. If the A/D converter is not used, do not leave the AV

CC, AVSS, and Vref pins open.

Connect AV

CC and Vref to VCC, and connect AVSS to VSS.

2. Current dissipation values are for V

IH min = VCC –0.5 V and VIL max = 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 ≤ VCC < 2.7 V, VIH min = VCC × 0.9, and VIL max = 0.3 V.

4. I

CC depends on VCC and f as follows:

CC max = 2.0 (mA) + 0.67 (mA/(MHz × V)) × VCC × f [normal mode]

CC max = 2.0 (mA) + 0.48 (mA/(MHz × V)) × VCC × f [sleep mode]

CC max = 2.0 (mA) + 0.07 (mA/(MHz × V)) × VCC × f [sleep, all module stop and medium

speed (

φ/32) mode]

5. The current dissipation for 32-kHz operation is the value when the duty adjustment

circuit is stopped.
