2. Current dissipation 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.

The values are for VRAM

≤ VCC < 3.0 V, VIH min = VCC × 0.9, and VIL max = 0.3 V.

3. ICC max. (normal operation)

= 6.0 (mA) + 0.577 (mA/(MHz

× V)) × VCC × f

ICC max. (sleep mode)

= 6.0 (mA) + 0.455 (mA/(MHz

× V)) × VCC × f

ICC max. (sleep mode + module standby mode)

= 6.0 (mA) + 0.344 (mA/(MHz

× V)) × VCC × f

The Typ values for power consumption are reference values.

4. Sum of current dissipation in normal operation and current dissipation in program/erase

operations.

Conditions: VCC = 3.0 V to 3.6 V, AVCC = 3.0 V to 3.6 V, VREF = 3.0 V to AVCC,

VSS = AVSS = 0 V, Ta = –20°C to +75°C (regular specifications),

Ta = –40°C to +85°C (wide-range specifications)

Notes: 1. To protect chip reliability, do not exceed the output current values in table 21.12.

2. When directly driving a darlington pair or LED, always insert a current-limiting resistor in

the output line, as shown in figures 21.4 and 21.5.
