Table 53. DC Parameters for Low Voltage

NOTES

ICC under reset is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 39.), VIL = VSS + 0.5 V,

VIH = VCC - 0.5V; XTAL2 N.C.; Vpp = RST = VCC. ICC would be slightly higher if a crystal oscillator used.

Idle ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH,TCHCL = 5 ns, VIL =VSS + 0.5 V, VIH =VCC - 0.5 V; XTAL2

N.C; Vpp = RST = VSS (see Figure 37.).
