[1] Typical ratings are not guaranteed. The values listed are at room temperature (25 °C), nominal supply voltages
[2] The RTC typically fails when V_i(VBAT) drops below 1.6 V.
[3] Including voltage on outputs in 3-state mode.
[4] V_DD(3V3) supply voltages must be present.
[5] 3-state outputs go into 3-state mode when V_DD(3V3) is grounded.
[6] Please also see the errata note in errata sheet.
[7] Accounts for 100 mV voltage drop in all supply lines.
[8] Allowed as long as the current limit does not exceed the maximum current allowed by the device.
[9] Minimum condition for V_I = 4.5 V, maximum condition for V_I = 5.5 V.
[10] On pin VBAT.
[11] To V_SSIO.
[12] Includes external resistors of 18 Ω ± 1 % on D+ and D−.
