DS1371U General Description


The DS1371 is a 32-bit binary counter that is designed to continuously count time in seconds. An additional counter that can generate a periodic alarm or serve as a watchdog timer is also provided. If enabled as a watchdog timer, the watchdog strobe input pin provides a hardware reset of the counter. If disabled, this counter can be used as 3 Bytes of general-purpose RAM. A configurable output can be used as an interrupt or provide a square wave at one of four selectable frequencies. The device is programmed serially through a I2C bidirectional bus.
