The DS1307 is a real-time clock (RTC) IC designed to keep track of time and date information. It is housed in a compact SOIC-8 surface-mount device (SMD) package, making it suitable for a variety of timekeeping applications in electronics. Here’s a detailed description of the product:
Key Features:
- Type: Real-Time Clock (RTC) IC
- Package: SOIC-8 (Small Outline Integrated Circuit)
- Operating Voltage: 4.5V to 5.5V
- Timekeeping Current: 300nA at 2.0V
- I²C Serial Interface: Simple communication with a microcontroller
- Timekeeping: Counts seconds, minutes, hours, day, date, month, and year with leap year compensation
- 56-Byte, Battery-Backed SRAM: Non-volatile storage for user data
- Programmable Square-Wave Output: Configurable frequency output for precise timing applications
Applications:
- Timekeeping: Ideal for keeping accurate time in various electronic devices.
- Data Logging: Useful in systems requiring time-stamped data.
- Industrial Control: Can be used for time-dependent operations in industrial systems.
- Consumer Electronics: Commonly used in clocks, alarms, and timers.
- Battery-Operated Devices: Suitable for battery-backed timekeeping in portable devices.
Pin Configuration:
- Pin 1 (X1): Connection for the external 32.768kHz crystal oscillator (input).
- Pin 2 (X2): Connection for the external 32.768kHz crystal oscillator (output).
- Pin 3 (VBAT): Backup supply input for maintaining timekeeping when the main power is off.
- Pin 4 (GND): Ground reference.
- Pin 5 (SDA): Serial data input/output for I²C communication.
- Pin 6 (SCL): Serial clock input for I²C communication.
- Pin 7 (SQW/OUT): Square-wave or output pin (programmable).
- Pin 8 (VCC): Primary power supply input.
Electrical Characteristics:
- Operating Voltage (Vcc): 4.5V to 5.5V
- Battery Voltage (VBAT): 2.0V to 3.5V
- Timekeeping Current: 300nA typical at VBAT = 2.0V
- I²C Interface: Supports standard and fast modes (100kHz and 400kHz)
- Oscillator: Requires a 32.768kHz crystal with 12.5pF load capacitance
