Description and Introduction

Trickle Charge Timekeeping Chip The DS1302ZN is a real-time clock (RTC) chip manufactured by Dallas Semiconductor (now part of Maxim Integrated). Here are its key specifications:

1. **Functionality**:  
   - Provides seconds, minutes, hours, day, date, month, and year information.  
   - Handles leap years up to 2100.  

2. **Interface**:  
   - Serial interface for communication with a microcontroller.  

3. **Power Supply**:  
   - Operates from a **2.0V to 5.5V** supply.  
   - Low power consumption in battery backup mode.  

4. **Backup Power**:  
   - Includes a trickle-charge circuit for a backup battery (typically 3V).  

5. **Package**:  
   - **8-pin DIP (Dual In-line Package)**.  

6. **Clock Accuracy**:  
   - Uses an external 32.768 kHz crystal oscillator.  

7. **Temperature Range**:  
   - **Commercial (0°C to +70°C)**.  

8. **Additional Features**:  
   - 31 bytes of general-purpose RAM.  
   - Simple 3-wire serial interface.  

This information is based on the manufacturer’s datasheet for the DS1302ZN. For precise details, refer to the official documentation.
