Notes 1: Test conditions: IOHL =

± 5mA, CL = 50 pF

2: twL(RD) = ((n + 0.5) • tc(PHI)) – 5 ns (n = wait number)

twL(WR) = ((n + 0.5) • tc(PHI)) – 5 ns (n = wait number)

For example, two software waits, PHI = 12 MHz operating

twL(RD) = 2.5 • tc(PHI) – 5 ns = 203.33 ns

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

value measured over 100 ms flowing through all the applicable ports.

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

3: The average output current is an average value measured over 100 ms.

4: The duty of oscillation frequency is 50

5: Connect a ceramic resonator or a quartz-crystal oscillator between the XIN and XOUT pins. Its maximum oscillation frequency must be 24 MHz. However,

make sure to set

φ to 6 MHz or slower. More faster clocks are required as the f(XIN) when using the frequency synthesizer as possible.

6: Connect a ceramic resonator or a quartz-crystal oscillator between the XCIN and XCOUT pins. Its maximum oscillation frequency must be 50 kHz. Input an

external clock having 5 MHz (max.) frequency from the XCIN pin.
