DS1302 Real Time Clock (RTC) IC – Trickle-Charge Timekeeping Chip

The DS1302 Real Time Clock (RTC) IC is an essential, low-power electronic component designed to keep accurate track of time and date in embedded systems. This trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with microcontrollers via a simple 3-wire serial interface, providing comprehensive time data including seconds, minutes, hours, day, date, month, and year. With its built-in backup battery management, it ensures uninterrupted timekeeping even when the main system power is completely disconnected.

At Electrapac (www.electrapac.com), we supply verified and original integrated circuits to support your automation, logging, and smart hardware prototyping across Bangladesh.

Key Features & Benefits:

• Complete Timekeeping Solution: Manages seconds, minutes, hours, day of the week, date, month, and year with leap-year compensation valid up to the year 2100.

• Low Power Consumption: Operates on less than 300nA at 2.0V, making it highly efficient for long-term battery backup deployments.

• Trickle-Charge Capability: Dual power supply pins allow for a primary power source and a backup rechargeable battery or supercapacitor with programmable trickle-charging.

• Simple 3-Wire Interface: Uses a highly efficient serial interface (CE, I/O, SCLK) instead of complex I2C or SPI, reducing the number of microcontroller pins required.

• Onboard NVRAM: Features 31 bytes of nonvolatile scratchpad memory to store custom system parameters or status flags securely.

Common Applications:

• Data Logging Systems requiring precise time-stamped records (e.g., SD Card logging).

• DIY Digital Clocks, Alarm Systems, and LED Matrix Time Displays.

• Attendance Systems, Smart Access Locks, and Industrial Timers.

• Scheduled Task Automation in Arduino, ESP32, and PIC microcontroller projects.
