Description
General part information
DS1672 Series
The DS1672U-33+ is an I2C 32bit binary counter RTC in 8 pin µSOP package. The DS1672 incorporates a 32bit counter and power monitoring functions. The 32 bit counter is designed to count seconds and can be used to derive time of day, week, month, month and year by using a software algorithm. A precision temperature-compensated reference and comparator circuit monitors the status of VCC. When an out of tolerance condition occurs, an internal power-fail signal is generated that forces the reset to the active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for a period of time to allow the power supply and processor to stabilize.
