Description and Introduction

Trickle Charge Timekeeping Chip The DS1302S-16 is a real-time clock (RTC) chip manufactured by DALLAS (now part of Maxim Integrated). Here are its key specifications:

1. **Function**: Provides seconds, minutes, hours, day, date, month, and year information with leap-year compensation.
2. **Interface**: Serial interface for communication with a microcontroller.
3. **Clock Format**: 12-hour or 24-hour format with AM/PM indicator.
4. **Power Supply**:
   - **Operating Voltage**: 2.0V to 5.5V.
   - **Backup Power**: Can be powered by a battery or supercapacitor (typically 3V).
5. **Low Power Consumption**: Consumes less than 300nA in battery backup mode.
6. **Temperature Range**: Operates from -40°C to +85°C.
7. **Package**: 16-pin SOIC (Small Outline Integrated Circuit).
8. **Additional Features**:
   - 31 x 8 bytes of general-purpose RAM.
   - Programmable trickle charger for backup power source.
   - Simple 3-wire interface (data, clock, chip select).
9. **Accuracy**: Typical timekeeping accuracy depends on the external crystal (usually 32.768kHz).

For exact details, refer to the official datasheet from Maxim Integrated.
