NOTES:

1. The operating supply current is measured with all output pins disconnected; XTAL 1 driven with tR = tF = 10ns;

VIL = VSS; VIH = VDD; XTAL 2 not connected; EA = RST = Port 0 = VDD; all open drain outputs connected to VSS.

2. The idle mode supply current is measured with all output pins disconnected; XTAL 1 driven with tR = tF = 10ns;

VIL = VSS. XTAL 2 not connected; EA = Port 0 = VDD; RST = VSS; all open drain outputs connected to VSS.

3. The power-down current is measured with all output pins disconnected; XTAL 1 not connected;

EA = Port 0 = VDD; RST = VSS; all open drain outputs connected to VSS.

4. Please note, option “ON” is only available on P80CL51.
