The DS1672 incorporates a 32-bit 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, 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.
The DS1672 provides a 32-bit counter that increments once-per-second. The counter data is accessible via an I²C serial interface. A precision, temperature-compensated, voltage reference and comparator circuit monitors Vcc. The DS1672 operates as a slave device on the I²C bus. Access is obtained by implementing a START condition and providing a device identification code followed by a register address. Subsequent registers can be accessed sequentially until a STOP condition is executed.
