I C, 32-Bit Binary Counter Watchdog RTC with  
Trickle Charger and Reset Input/Output  
General Description  
Features  
♦ 32-Bit Binary Counter  
The DS1374 is a 32-bit binary counter designed to contin-  
uously count time in seconds. An additional counter gen-  
erates a periodic alarm or serves as a watchdog timer. If  
disabled, this counter can be used as 3 bytes of non-  
volatile (NV) RAM. Separate output pins are provided for  
an interrupt and a square wave at one of four selectable  
frequencies. A precision temperature-compensated refer-  
♦ Second Binary Counter Provides Time-of-Day  
Alarm, Watchdog Timer, or NV RAM  
♦ Separate Square-Wave and Interrupt Output Pins

♦ I C Serial Interface  
♦ Automatic Power-Fail Detect and Switch Circuitry  
♦ Single-Pin Pushbutton Reset Input/Open-Drain  
ence and comparator circuit monitor the status of V

detect power failures, provide a reset output, and auto-  
matically 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 pro-
