DS1302 Real-Time Clock (RTC) Module with Battery Backup
€8.00
This DS1302 Real-Time Clock (RTC) module provides accurate timekeeping for microcontrollers, featuring a trickle-charge circuit for battery backup to maintain time even without main power.
The DS1302 Real-Time Clock module is a low-power, full binary-coded decimal (BCD) clock/calendar plus 31-byte static RAM. It communicates with a microcontroller via a simple 3-wire serial interface.
- Main IC: DS1302
- Operating Voltage: 2.0V to 5.5V
- Communication Interface: 3-wire serial (RST, I/O, SCLK)
- Timekeeping Features: Seconds, minutes, hours, day, date, month, and year information
- Leap Year Compensation: Valid up to 2100
- Battery Backup: Supports external battery for continuous timekeeping
- On-board Crystal: 32.768 kHz
- Applications: Time-stamping data loggers, alarm clocks, industrial control systems, smart home devices, and other projects requiring accurate timekeeping.
