Grove - High Precision RTC is a more accurate real-time-clock comparing to Grove – RTC with the regular clock chip DS1307. The heart of Grove – High Precision RTC is PHILIPS PCF85063TP, which is a CMOS chip that optimized for low power consumption, the typical current can be less than 1.2uA at certain environment.

• Provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768KHz quartz crystal
• Clock operating voltage from 0.9V to 5.5V
• Low current: typical less than 1.2μA at VDD = 3.3V and Tamb = 25°C
• Up to 400KHz two-line I²C-bus interface (at VDD = 1.8V to 5.5V)
• Programmable clock output for peripheral devices (32.768, 6.384, 8.192, 4.096, 2.048, 1.024kHz, 1Hz)
• Selectable integrated oscillator load capacitors for CL = 7pF or CL = 12.5pF
• Minute and half minute interrupt
• Internal power-on reset (POR)
• Programmable offset register for frequency adjustment
• Compatible platform：Arduino, BeagleBone Green, BeagleBone Green Wireless,
