I C, 32-Bit Binary Counter Watchdog RTC with  
Trickle Charger and Reset Input/Output  
General Description  
Features  
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-
