DS1501/DS1511  
Y2K-Compliant Watchdog  
Real-Time Clocks  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1501/DS1511 are full-function, year 2000-  
compliant real-time clock/calendars (RTCs) with an  
RTC alarm, watchdog timer, power-on reset, battery  
monitors, 256 bytes NV SRAM, and a 32.768kHz  
output. User access to all registers within the  
DS1501/DS1511 is accomplished with a byte-wide  
interface, as shown in Figure 8. The RTC registers  
contain century, year, month, date, day, hours,  
minutes, and seconds data in 24-hour binary-coded  
decimal (BCD) format. Corrections for day of month  
and leap year are made automatically.  
Cꢀ BCD-Coded Century, Year, Month, Date, Day,  
Hours, Minutes, and Seconds with Automatic  
Leap-Year Compensation Valid Up to the Year  
2100  
Cꢀ Programmable Watchdog Timer and RTC Alarm  
Cꢀ Century Register; Y2K-Compliant RTC  
Cꢀ +3.3 or +5V Operation  
Cꢀ Precision Power-On Reset  
Cꢀ Power-Control Circuitry Support System Power-  
On from Date/Day/Time Alarm or Key  
Closure/Modem-Detect Signal  
Cꢀ 256 Bytes Battery-Backed NV SRAM  
Cꢀ Auxiliary Battery Input  
APPLICATIONS  
Cꢀ Accuracy of DS1511 Better than ±1  
Minute/Month at +25°C  
Remote Systems  
Battery-Backed Systems  
Telecom Switches  
Office Equipment  
Cꢀ Day-of-Week/Date Alarm Register  
Cꢀ Crystal Select Bit Allow RTC to Operate with 6pF  
or 12.6pF Crystal  
Consumer Electronics  
Cꢀ Battery Voltage-Level Indicator Flags  
Cꢀ Available as Chip (DS1501) or Stand-Alone  
Module with Embedded Battery and Crystal  
(DS1511)
