Description

RTC W/ SRAM 236BYTE NSOIC-8
The DS3232M is a low-cost, extremely accurate, I2C real-time clock (RTC) with 236 bytes of battery-backed SRAM. The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the microelec- tromechanical systems (MEMS) resonator enhances the long-term accuracy of the device and 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-hour or 12-hour format with an AM/PM indicator. Two programmable time-of-day alarms and a 1Hz output are provided. Address and data are transferred serially through an I2C 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 neces- sary. Additionally, the RST pin is monitored as a pushbut- ton input for generating a microprocessor reset. See the Block Diagram for more details.
