DS3232 Description
The DS3232 is a low-cost temperature-pensated crystal oscillator (TCXO) with a very accurate, temperature-pensated, integrated real-time clock (RTC) and 236 bytes of battery-backed SRAM. Additionally, the DS3232 incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as...
