DS1386/DS1386P  
RAMified Watchdog Timekeeper  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1386 is a nonvolatile static RAM with a  
full-function real-time clock (RTC), alarm,  
watchdog timer, and interval timer that are all  
accessible in a byte-wide format. The DS1386  
contains a lithium energy source and a quartz  
crystal, which eliminates the need for any external  
circuitry. Data contained within 8k or 32k by 8-bit  
memory and the timekeeping registers can be read  
or written in the same manner as byte-wide static  
RAM. The timekeeping registers are located in the  
first 14 bytes of memory space. Data is maintained  
in the RAMified timekeeper by intelligent control  
circuitry, which detects the status of VCC and write  
protects memory when VCC is out of tolerance. The  
lithium energy source can maintain data and real  
time for over ten years in the absence of VCC.  
Timekeeper information includes hundredths of  
seconds, seconds, minutes, hours, day, date, month,  
and year. The date at the end of the month is  
automatically adjusted for months with less than 31  
days, including correction for leap year.  
ꢀ 8kB or 32kB of User NV RAM  
ꢀ Integrated NV SRAM, Real-Time Clock,  
Crystal, Power-Fail Control Circuit, and  
Lithium Energy Source  
ꢀ Totally Nonvolatile With Over 10 Years of  
Operation in the Absence of Power  
ꢀ Watchdog Timer Restarts an Out-Of-  
Control Processor  
ꢀ Alarm Function Schedules Real-Time  
Related Activities such as System Wakeup  
ꢀ Programmable Interrupts and Square-  
Wave Output  
ꢀ All Registers are Individually Addressable  
via the Address and Data Bus  
ꢀ Interrupt Signals are Active in Power-  
Down Mode  
The RAMified timekeeper operates in either 24-  
hour or 12-hour format with an AM/PM indicator.  
The watchdog timer provides alarm interrupts and  
interval timing between 0.01 seconds and 99.99  
seconds. The real-time alarm provides for preset  
times of up to one week. Interrupts for both  
watchdog and RTC operate when the system is  
powered down. Either can provide system “wake-  
up” signals.  
Pin Configurations appear at end of data sheet.
