R2025S/D High precision I²C-Bus Real-Time Clock Module
FEATURES:
●Built in 32.768kHz crystal unit, The oscillation frequency is adjusted to high precision (0±5ppm: at 25°C)
●Time keeping voltage 1.15V to 5.5V
●Super low power consumption 0.48μA TYP (1.2μA MAX) at VDD=3V
●I2C-Bus interface (Maximum serial clock frequency: 400KHz at VDD≥1.7V)
●Time counters (counting hours, minutes, and seconds) and calendar counters (counting years, months, days, and weeks) (in BCD format)
●Interrupt circuit configured to generate interrupt signals (with interrupts ranging from 0.5 seconds to 1 month) to the CPU and provided with an interrupt flag and an interrupt halt
●2 alarm interrupt circuits (Alarm_W for week, hour, and minute alarm settings and Alarm_D for hour and minute alarm settings)
●32.768kHz Clock CMOS push-pull output with control pin
●With Power-on flag to prove that the power supply starts from 0V⋅With Oscillation halt sensing Flag to judge the validity of internal data
●Supply voltage monitoring circuit with two supply voltage monitoring threshold settings
●Automatic identification of leap years up to the year 2099
●Selectable 12-hour and 24-hour mode settings
●Oscillation adjustment circuit for correcting temperature frequency deviation or offset deviation
●CMOS process
●Two types of package, SOP14(10.1x7.4x3.1) or SON22(6.1x5.0x1.3)
