Note 1: Limits at -40°C are not production tested and are guaranteed by design.
Note 2: Voltage referenced to ground.
Note 3: Outputs are open.
Note 4: The IRQ, PWR, and RST outputs are open drain.
Note 5: Value for voltage and currents is from the VCCI input pin to the VCCO pin.
Note 6: If VPF is less than VBAT and VBAUX, the device power is switched from VCC to the greater of VBAT or VBAUX when VCC drops below VPF. If VPF
is greater than VBAT and VBAUX, the device power is switched from VCC to the greater of VBAT or VBAUX when VCC drops below the greater
of VBAT or VBAUX.
Note 7: Value for voltage and currents is from the VBAT or VBAUX input pin to the VCCO pin.
Note 8: IBAT1 and IBAT2 are specified with VCCO unconnected and do not include any RAM current.
Note 9: VBAT or VBAUX current. Using a 32.768kHz crystal connected to X1 and X2.
Note 10: These parameters are sampled with a 5pF load and are not 100% tested.
Note 11: Typical values are at +25°C, nominal (active) supply, unless otherwise noted.
Note 12: If the oscillator is not enabled, the startup time of the oscillator after VCCI is applied is added to the wakeup/kickstart timeout.
