REAL TIME CLOCK MODULE (SPI-Bus)
High stability Frenquency with Built in Timestamp and Power Switching
- Buit in 32.768 kHz crystal unit : Frenquency adjusted for high accuracy
- Interface type: SPI-Bus (1 MHz)
- Operating voltage range : 2.4 V to 5.5 V
- Timekeeping voltage range : 1.0 V to 5.5 V
- Low backup current : 350 nA(SA) 400 nA(LC)/ 3 V (Typ.)
- Dual event detection ports: each terminal has a de-bounce circuit.
- Auto power switching functions: When VDD deteriorates than 2.4 V internal source is switched to VBAT
