tCLCH = tCHCL = 5ns

NOTES :

1. Icc(active mode) is measured with:

Xtal1 driven with tCLCH = tCHCL = 5ns, VIL = Vss + 0.5V, VIH = Vcc - 0.5V, X2 = N.C.

Reset = Vcc, all other pins are disconnected.

Icc would be slightly higher if a crystal oscillator is used (appr. 1mA)

2. Icc(power down mode) is measured with:

Xtal1 = Vss, Xtal2 = N.C., Reset = Vss, all other pins are disconnected.
