DS1284/DS1286  
Watchdog Timekeepers  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1284/DS1286 watchdog timekeepers are ꢀ Keeps Track of Hundredths of Seconds,  
self-contained real-time clocks, alarms, watchdog  
timers, and interval timers in a 28-pin JEDEC DIP  
and encapsulated DIP package. The DS1286  
Seconds, Minutes, Hours, Days, Date of the  
Month, Months, and Years; Valid Leap Year  
Compensation Up to 2100  
contains an embedded lithium energy source and a ꢀ Watchdog Timer Restarts an Out-of-Control  
quartz crystal, which eliminates the need for any  
external circuitry. The DS1284 requires an external ꢀ Alarm Function Schedules Real-Time-Related  
quartz crystal and a VBAT source, which could be a Activities  
Processor  
lithium battery. Data contained within 64 8-bit ꢀ Embedded Lithium Energy Cell Maintains  
registers can be read or written in the same manner  
as byte-wide static RAM. Data is maintained in the  
Time, Watchdog, User RAM, and Alarm  
Information  
watchdog timekeeper by intelligent control circuitry ꢀ Programmable Interrupts and Square-Wave  
that detects the status of VCC and write protects  
memory when VCC is out of tolerance. The lithium ꢀ All Registers are Individually Addressable via  
energy source can maintain data and real time for the Address and Data Bus  
over 10 years in the absence of VCC. Watchdog ꢀ Accuracy is Better than ±1 Minute/Month at  
timekeeper information includes hundredths of +25°C (EDIP)  
seconds, seconds, minutes, hours, day, date, month, ꢀ Greater than 10 Years of Timekeeping in the  
Outputs Maintain JEDEC Footprint  
and year. The date at the end of the month is  
Absence of VCC  
automatically adjusted for months with fewer than ꢀ 50 Bytes of User NV RAM  
31 days, including correction for leap year. The ꢀ Underwriters Laboratory (UL) Recognized  
DS1284/DS1286 operate in either 24-hour or 12- ꢀ -40°C to +85°C Industrial Temperature Range  
hour format with an AM/PM indicator. The devices  
provide alarm windows and interval timing between  
0.01 seconds and 99.99 seconds. The real-time  
alarm provides for preset times of up to one week.

Pin Configurations appear at end of data sheet.
