Low-Current I2C RTCs for High-ESR Crystals
DS1341/DS1342
Note 11: CB is the total capacitance of one bus line, including all connected devices, in pF.
Note 12: Guaranteed by design; not 100% production tested.
Note 13: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage
range of 2.4V P VCC P VCCMAX.
Note 14: The DS1341/DS1342 can detect any single SCL clock held low longer than tTIMEOUTMIN. The devices’ I2C interface is
in reset state and can receive a new START condition when SCL is held low for at least tTIMEOUTMAX. Once the device
detects this condition, the SDA output is released. The oscillator must be running for this function to work.
