RECOMMENDED OPERATING CONDITIONS (Cont’d)

(TA=0 to +70

oC, V

DD-VSS=5.5V unless otherwise specified)

Notes:

1. CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS; clock input (OSC1)

driven by external square wave.

2. All I/O pins in input mode with a static value at VDD or VSS; clock input (OSC1) driven by external square wave.

T = 0... +70oC, voltages are referred to VSS unless otherwise specified:

Note 1 : Hysteresis voltage between Schmitt trigger switching levels. Based on characterisation results, not tested.

Note 2 : Guaranteed by Characterization
