ALLNET DS1302 Real-Time Clock RTC kit Multicolour compatible with 4Duino

The ALLNET DS1302 Real-Time Clock RTC kit in multicolour, model All_RTC_DS1302, is a reliable module designed for precise timekeeping and calendar tracking in various electronics projects and embedded systems. Built around the DS1302 trickle-charge timekeeping chip, this module communicates efficiently with microprocessors using a simple synchronous serial interface. It handles complete time and date information, including seconds, minutes, hours, day, date, month, and year, while automatically adjusting for shorter months and leap years. Designed for low-power operation, the module ensures efficient performance and data retention for your development boards.

Advantages

The ALLNET DS1302 Real-Time Clock RTC kit offers dual power pins supporting both primary and backup power supplies to maintain continuous operation. Its low-power consumption allows it to retain clock information and data on minimal energy. The simplified three-wire serial interface ensures straightforward communication with a microprocessor using CE, I/O, and SCLK lines. Additionally, the integrated static RAM provides 31 bytes of memory for supplementary data storage.

Suitable for

• Embedded systems and microcontroller projects requiring accurate time and date tracking
• DIY electronics development boards such as 4Duino and compatible ALLNET systems
• Projects needing automatic leap year correction and month-end adjustments
• Prototyping applications utilizing low-power serial communication modules

When it may not be suitable

This real-time clock kit may not be suitable for projects that require high-precision atomic timekeeping or synchronization over complex network protocols without external assistance. It is also not designed for standalone industrial deployment without a compatible microcontroller or development board to handle the serial interface.

Key specifications

• Equipped with the DS1302 trickle-charge timekeeping chip
• Real-time clock and calendar tracking seconds, minutes, hours, day, date, month, and year
• Supports both 24-hour and 12-hour formats with an AM/PM indicator
• Includes 31 bytes of static RAM
• Synchronous serial interface using three communication wires: CE, I/O, and SCLK
• Dual power pins for primary and backup power supplies
• Programmable trickle charger for VCC1
• Low-power operation consuming less than 1uW for data and clock retention

How to use

To integrate the ALLNET DS1302 Real-Time Clock RTC kit into your project, connect the module to your microcontroller using the three primary serial interface lines: Chip Enable (CE), Input/Output data line (I/O), and Serial Clock (SCLK). Ensure that both primary and backup power supplies are correctly connected to the dual power pins to maintain continuous timekeeping during power transitions. You can communicate with the clock and static RAM by transferring data one byte at a time or in a burst of up to 31 bytes through the microprocessor software routine.

What to consider before purchase

• Check compatibility with your specific development board, such as 4Duino or ALLNET systems.Verify that your project requirements align with a three-wire synchronous serial communication interface.Ensure you have a suitable primary and backup power supply configuration for the dual power pins.

Usage recommendations

Always verify wiring connections for the CE, I/O, and SCLK lines before powering on the microcontroller to ensure stable serial communication and prevent data transfer errors.
