(2) Difference between VDDSWR and VDDSWF. (3) VBACKUP must be higher than VDD by at least this voltage to insure the AB-RTCMC-32.768kHz-IBO5-S3 remains in the VBACKUP Power state. (4) Maximum VDD falling slew rate to guarantee correct switchover to VBACKUP Power state. There is no VDD falling slew rate requirement if switching to the VBACKUP power source is not required. (5) VBACKUP voltage to guarantee correct transition to VBACKUP Power state when VDD falls. (6) Total series resistance of the power source attached to the VBACKUP pin. The optimal value is 1.5 kΩ, which may require an external resistor. VBACKUP power source ESR (Equivalent Series Resistance) + external resistor value = 1.5 kΩ.

Units ppm +60 °C (1) Timing accuracy is specified at 25°C after digital calibration of the internal RC oscillator and digital calibration of the 32.768 kHz crystal. The 32.768 kHz tuning fork crystal has a negative temperature coefficient with a parabolic frequency deviation, which can result in a change of up to 150 ppm across the entire operating temperature range of -40°C to 85°C in XT mode. Autocalibration mode timing accuracy is specified relative to XT mode timing accuracy from -10°C to 60°C. (2) Outside of this temperature range, the RC oscillator frequency change due to temperature may be outside of the allowable RC digital calibration range (+/-12%) for autocalibration mode. When this happens, an autocalibration failure will occur and the ACF interrupt flag is set. The AB-RTCMC-32.768kHz-IBO5-S3 should be switched to use the XT oscillator as its clock source when this occurs. Please see the AUTOCALIBRATION FAILURE section in the application manual for more details. XT Frequency Characteristics TA = -40 to +85°C unless otherwise indicated.
