4126J–CAN–05/06

Maximum IOL per 8-bit port:

Ports 1, 2 and 3: 15 mA

Maximum total IOL for all output pins: 71 mA

If I

OL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater

than the listed test conditions.

4. Power-down ICC is measured with all output pins disconnected; XTAL2 NC.; RST = VSS (See Figure 61.).

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

0.5V; XTAL2 N.C; RST = VSS (See Figure 60.).

6. Operating ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (See Figure 62.), VIL =

SS + 0.5V, VIH = VCC - 0.5V; XTAL2 N.C.; RST = VCC. ICC would be slightly higher if a crystal oscillator used (See Figure

59.).
