Main clock input oscillation frequency

Vcc = 4.00 to 5.25 V

(Note 4)

Vcc = 3.00 to 4.00 V

System clock frequency

Vcc = 4.00 to 5.25 V

Vcc = 3.00 to 4.00 V

φ frequency

Vcc = 4.00 to 5.25 V

Vcc = 3.00 to 4.00 V

Typ.

Min.

Notes 1: The total peak output current is the absolute value of the peak currents flowing through all the applicable ports. The total average output current is

the average value of the absolute value of the currents measured over 100 ms flowing through all the applicable ports.

2: The peak output current is the absolute value of the peak current flowing in each port.

3: The average output current is the average value of the absolute value of the currents measured over 100 ms.

4: The duty of oscillation frequency is 50

%. 6 MHz or 12 MHz is usable.
