DS3232 Extremely Accurate I²C RTC With Integrated Crystal And SRAM

The DS3232 is a 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 DS3232 is available in commercial and industrial temperature ranges, and is offered in an industry-standard 20-pin, 300-mil SO package.
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-hour or 12-hour format with an active-low AM/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an IC bidirectional bus.
A precision temperature-compensated Voltage Reference and Comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically Switch to the backup supply when necessary. Additionally, the active-low RST pin is monitored as a pushbutton input for generating a reset externally.
