11.3 Recommended Operating Condition
Operating condition: VDD=5V
±10%; TA=0/125°C (unless otherwise specified).
Notes:
1. It is reccomendend to insert a capacitor beetwen VDD and VSS for improving noise rejection. Rec-
comended values are 10
µF (electrolytic or tantalum) and/or 100 nF (ceramic).
2. A lower VDD decreasing fosc (see Figure 11.3). Data illustrated in the figure are characterized but not
tested.
Figure 11.3 fosc Maximum Operating Frequency versus VDD supply (*)
(*) Only digital parts of the device: the Analog Comparator cannot work with supply voltage lower
than 4.5 V.
