Notes:
1. The V_CC voltage specification of 3.0V guarantees 3.3V ±0.3V with typicals at V_CC = 3.3V, and the V_CC voltage
specification of 5.5V guarantees 5.0V ±0.5V with typicals at V_CC = 5.0V.
2. Typicals are at V_CC = 5.0V and 3.3V.
3. Standard Mode (not Low EMI).
4. Not applicable to devices in 28-pin packages.
5. For analog comparator, inputs when analog comparators are enabled.
6. All outputs unloaded, I/O pins floating, inputs at rail.
7. Same as note 6, except inputs at V_CC.
8. Clock must be forced Low, when XTAL 1 is clock-driven and XTAL2 is floating.
9. 0ºC to 70ºC (standard temperature).
10. Auto Latch (Mask Option) selected.
11. The V_LV voltage increases as the temperature decreases and overlaps lower V_CC operating region.
12. –40˚C to 150˚C (extended temperature).
