Product description
RTC module based on the DS1302 real-time clock. RTC stands for Real-Time Clock. As long as the DS1302 is powered via a backup battery, it keeps track of time for microcontroller-based systems and computers with high accuracy. The module provides timekeeping and calendar functions including seconds, minutes, hours, date, month, day of the week, and year, with automatic leap-year compensation up to the year 2100.
Specifications:
- Supply voltage: 2.0 V to 5.5 V
- Backup battery: CR1220, 3.0 V
- Operating temperature range: 0 °C to +70 °C
- Power consumption: less than 1 mW while retaining clock and RAM data
- Module dimensions: 31 x 15 mm
- Communication interface: SPI with support for 3- and 4-wire serial communication
- Time format: selectable 24-hour format or 12-hour format with AM/PM indicator
Applications:
Typical applications include timekeeping in portable devices, electronic clocks, data logging systems, and other embedded systems that require accurate time management with backup functionality.
