DS3232SN#T&R (MAXIM INTEGRATED PRODUCTS)

The DS3232SN#T&R from Maxim Integrated Products is an extremely accurate I2C RTC with integrated crystal and SRAM in 20 pin SOIC package. This low cost temperature compensated crystal oscillator (TCXO) with a very accurate, temperature compensated, 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 reduces the piece-part count in a manufacturing line. The RTC maintains seconds, minutes, hours, day, date, month and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24/12hour format with an AM (active low)/PM indicator. It is used in servers, telematics, utility power meters and GPS.
