10.1 General characteristics

Absolute maximum ratings in the table of "Voltage and current operating ratings" section

are stress ratings only, and functional operation at the maximum is not guaranteed. Stress

beyond these ratings may affect device reliability or cause permanent damage to the

device.

Unless otherwise stated, all specifications within this chapter apply to the temperature

range specified in the table of "Voltage and current operating ratings" section over the

following supply ranges: VSS = VSSA = 0 V, VDD = VDDA = 3.0 V to 3.6 V, CL ≤ 50 pF,

fOP = 50 MHz.

CAUTION

This device contains protective circuitry to guard against

damage due to high static voltage or electrical fields. However,

normal precautions are advised to avoid application of any

voltages higher than maximum-rated voltages to this high-

impedance circuit. Reliability of operation is enhanced if

unused inputs are tied to an appropriate voltage level.

10.2 AC electrical characteristics

Tests are conducted using the input levels specified in the section "Voltage and current

operating behaviors". Unless otherwise specified, propagation delays are measured from

the 50% to the 50% point, and rise and fall times are measured between the 20% and 80%

points, as shown in Figure 5.

All digital I/O switching characteristics, unless otherwise specified, assume that the

output pins have the following characteristics.

• CL=30 pF loads

• Slew rate disabled

• Normal drive strength
