    Banana Pi BPI-A-010 RTC module

    The RTC module is specifically designed for the Banana Pi. It communicates with the Banana Pi through the I2C bus. There is a Maxim DS3231 chip and 0.2uF SuperCapacitor on the board to keep the real time for a long time after the BananaPi was powered off.

    Features

    • Maxim DS3231 chip
    • 0.2uF Super Capacitor
    • Can be operated by a shell

    Port

    • Banana Pi connection port, also can be used on a Raspberry Pi.

    Product parameters

    • Accuracy ±2ppm from 0°C to +40°C
    • Battery backup input for continuous time keeping
    • Real-time clock counts seconds, minutes, hours, days, months and years with leap year compensation valid up to 2100
    • Digital temp sensor output: ±3°C accuracy
    • Two time-of-day alarms

    Typical applications

    • Smart home
    • Utility power meters
    • Telematics

    More information
    The DS3231 is a low-cost, extremely accurate I2C realtime clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when the main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line.
    The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with less than 31 days, including corrections for leap years. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided.
    Address and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and automatically switch to the backup supply when necessary. Additionally, the RST,pin is monitored as a pushbutton input for generating a μP reset.
