PRELIMINARY DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD4992  
8-Bit Parallel I/O Calendar Clock  
The µPD4992 is a CMOS integrated circuit which outputs 8-bit parallel time and calendar data in a system in which  
a microprocessor is employed. The µPD4992 operates at 32.768 kHz and provides year, month, day of month, day  
of week, hour, minute, and second data to a system. The µPD4992 internally contains a voltage regulator so that  
low power consumption operation and high accuracy are realized even if the supply voltage varies. The µPD4992  
uses the 8-bit bus to facilitate interfacing with a microprocessor.  
FEATURES:  
Internal counter for time (hour, minute, second), and calendar (leap year, year, month, day of month, day of week)  
Super low power consumption (IDD = 2 µA MAX. at VDD = 2.4 V)  
Automatic determination of leap year, manual setting possible  
12 hour/24 hour mode selectable  
8-bit parallel input/output in BCD data format  
12 kinds of interval timer output (can be used as watchdog timer)  
Internal voltage detection circuit for automatic determination of battery run-down  
High accuracy
