R2025S-E2-FE Descrizione generale

The R2025S/D is a real-time clock module, built in CMOS real-time clock IC and crystal oscillator, connected to the CPU by two signal lines, SCL and SDA, and configured to perform serial transmission of time and calendar data to the CPU. The oscillation frequency is adjusted to high precision (0±5ppm: 13sec. per month at 25°C) The periodic interrupt circuit is configured to generate interrupt signals with six selectable interrupts ranging from 0.5 seconds to 1 month. The 2 alarm interrupt circuits generate interrupt signals at preset times.

Caratteristiche principali

⋅ 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)
