The DS1374 is a 32-bit binary counter designed to continuously
count time in seconds. An additional counter generates
a periodic alarm or serves as a watchdog timer. If
disabled, this counter can be used as 3 bytes of nonvolatile
(NV) RAM. Separate output pins are provided for
an interrupt and a square wave at one of four selectable
frequencies. A precision temperature-compensated reference
and comparator circuit monitor the status of VCC to
detect power failures, provide a reset output, and automatically
switch to the backup supply when necessary.
Additionally, the reset pin is monitored as a pushbutton
input for externally generating a reset. The device is programmed
serially through an I²C serial interface.
