1.
Valid for ambient operating temperature: TA = –40 to 85°C; VCC1 = 0.8 to 5.5V and VCC2 = 0.8 to 3.6V (except where noted).
2.
Input leakage for the MRC pin is not tested.
3.
Guaranteed by design.
4.
The leakage current measured on the RST pin is tested with the reset de-asserted (output high impedance).
5.
Selecting the appropriate external capacitor (preferably less than 100pF) allows systems designers to vary the minimum delay from 6s (MRC pin left open) or more
(see Table 7).
