The DS3234 is a high-precision, low-power real-time clock (RTC) integrated circuit that features an internal temperature-compensated crystal oscillator (TCXO) and crystal. Communicating via an SPI interface, this RTC chip delivers timekeeping accuracy of ±2 ppm, making it ideal for applications requiring dependable and accurate time tracking. It features dual alarms, a programmable square-wave output, and an integrated digital temperature sensor.
Designed for direct integration onto printed circuit boards (PCBs), the DS3234 eliminates the need for external crystals or oscillators, simplifying circuit design while enhancing performance.
