DS3231 Real Time Clock Module for Raspberry Pi

DS3231 Real Time Clock Module for Raspberry Pi โมดูลนาฬิกา Real Time Clock ใช้ไอซีเบอร์ DS3231 มีเซนเซอร์อุณหภูมิในตัว พร้อมแบตเตอร์รี่ The DS3231 is a low-cost, extremely accurate I2C real- time clock (RTC) with an integrated temperature- compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accu- rate timekeeping when main power to the device is inter- rupted. 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. คุณสมบัติ DS3231 Real Time Clock Module for Raspberry Pi - Accuracy 2ppm from 0C to +40C - Accuracy 3.5ppm from -40C to +85C - Battery Backup Input for Continuous Timekeeping - Operating Temperature Ranges - Commercial: 0C to +70C, Industrial: -40C to +85C - Low-Power Consumption - Real-Time Clock Counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap Year Compensation Valid Up to 2100 - Two Time-of-Day Alarms - Programmable Square-Wave Output - Fast (400kHz) I2C Interface - 3.3V Operation - Digital Temp Sensor Output: 3C Accuracy - Register for Aging Trim - RST Output/Pushbutton Reset Debounce Input - Underwriters Laboratories (UL) Recognized
