Description
The RTC6659E is a real-time clock (RTC) module with an integrated temperature-compensated crystal oscillator (TCXO), designed for high-precision timekeeping. Key features include:
- Low power consumption (suitable for battery-backed applications).
- I²C interface for easy communication with microcontrollers.
- Built-in TCXO for improved accuracy (±5 ppm typical).
- Automatic leap-year correction and alarm functions.
- Wide operating voltage (typically 1.8V–5.5V).
Commonly used in IoT devices, embedded systems, and industrial applications where reliable timekeeping is critical. The module often includes EEPROM for data storage and supports timestamp logging.
