Real-Time Clock Module DS1302 by uxcell for AVR ARM Microcontrollers

The DS1302 Real-Time Clock Module from uxcell is a reliable and compact solution for adding precise timekeeping to microcontroller projects. It features a built-in clock and calendar that tracks seconds, minutes, hours, days, weeks, months, and years, with automatic adjustments for leap years and varying days per month. This makes it ideal for applications requiring accurate time tracking without the need for external software handling.

The module communicates with microcontrollers like AVR and ARM through a simple serial interface, using a 3-wire connection that minimizes pin usage. It supports both single-byte and multi-byte data transfer modes, allowing flexibility in how data is read or written. The device operates within a wide voltage range of 3.3V to 5V, making it compatible with various power supplies and microcontroller setups.

Designed for ease of integration, the DS1302 comes in an 8-pin DIP package or an 8-pin SOIC surface mount option. Its small PCB size of 43mm x 23mm ensures it fits into tight spaces on breadboards or PCBs. The module also includes 31 bytes of static RAM for storing additional data, which can be useful for logging or temporary storage in embedded systems.

This module is particularly useful for hobbyists and professionals working on projects such as digital clocks, data loggers, or time-stamped sensors. It simplifies time management in embedded systems by offloading the task to a dedicated chip. However, it lacks built-in battery backup, so users must ensure a stable power source or add an external backup battery for continuous operation.
