NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification is not implied.
2. Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum I_OL per port pin:
10mA
Maximum I_OL per 8-bit port:
26mA
Maximum total I_OL for all outputs: 67mA
If I_OL exceeds the test condition, V_OL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.
4. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V_SS unless otherwise
noted.
5. Power-down I_CC is measured with all output pins disconnected; port 0 = V_CC; X2, X1 n.c.; RST = V_SS.
6. I_CC is measured with all output pins disconnected; X1 driven with t_CLCH, t_CHCL = 5ns, V_IL = V_SS + 0.5V, V_IH = V_CC – 0.5V; X2 n.c.;
RST = port 0 = V_CC. I_CC will be slightly higher if a crystal oscillator is used.
7. Idle I_CC is measured with all output pins disconnected; X1 driven with t_CLCH, t_CHCL = 5ns, V_IL = V_SS + 0.5V, V_IH = V_CC – 0.5V; X2 n.c.;
port 0 = V_CC; RST = V_SS.
8. Load capacitance for ports = 80pF.
