Fermion: DS3232 Precise RTC (Breakout)

This real-time clock module equipped with the DS3232 chip is a sophisticated solution for precise timekeeping. Its integrated crystal resonator paired with a temperature compensator ensures incredible long-term accuracy. Remarkably, it maintains accuracy at ±3.5ppm, translating to a variance of just ±0.3024 seconds per day, even in temperatures ranging from -40°C to +85°C.

Boasting 236-byte SRAM storage, this module excels in scenarios demanding minimal power, such as in the Internet of Things. This feature ensures data retention without frequent power source dependencies, enhancing the efficiency of various applications. Coupled with an incorporated battery input, the clock maintains precision even when the primary power supply is disrupted.

Offering detailed time information, the RTC supports both 24-hour and 12-hour formats, complete with an AM/PM indicator. It conveniently updates dates at the end of each month, factoring in leap years. Its dual programmable alarms and square-wave output innovatively enhance its functionality, providing flexibility for various timing requirements. Additionally, its RST pin supports push-button input for microprocessor resets, adding to its versatility.

Transport regulations require purchasing the compatible CR1220 button cell battery separately due to restrictions on shipping items like batteries. This ensures uninterrupted power management while adhering to compliance standards. Equip your designs with a tool that embodies precision and efficiency, transforming ordinary projects into exceptional timekeeping marvels.
