ELECTRICAL CHARACTERISTICS

3.1 Electrical characteristics

Recommended operating conditions (Ta = –10 °C to 70 °C, VCC = 5 V ± 10 %, unless otherwise noted)

Notes 1: The total current that flows out of the IC must be 20 mA (max.).

2: The total input current to IC (IOL1 + IOL2 + IOL3) must be 30 mA or less.

3: The total average input current for ports P24–P27 to IC must be 20 mA or less.

4: Connect 0.1

µF or more capacitor externally across the power source pins VCC–VSS so as to

reduce power source noise. Also connect 0.1

µF or more capacitor externally across the pins

VCC–CNVSS.

5: Use a quartz-crystal oscillator or a ceramic resonator for the CPU oscillation circuit.
