Notes 1: VCC = 2.7 V to 5.5 V, VSS = 0 V, and Ta = –20

°C to 85°C (Ta = –40 °C to 85°C for extended

operating temperature range version), unless otherwise noted.

2: The limits when the key-on wakeup function of port P0 is used

3: When represented with electric resistance, the corresponding values are as follows:

• VCC = 5 V:

5 k

Ω (Min.),

10 k

Ω (Typ.), and 20 kΩ (Max.)

• VCC = 3 V: 8.6 k

Ω (Min.), 16.7 kΩ (Typ.), and 37.5 kΩ (Max.)
