® Data Sheet New Features October 23, 2006 ISL12026 FN8231.5 Real Time Clock/Calendar with EEPROM The ISL12026 device is a micro power real time clock with timing and crystal compensation, clock/calender, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching...
But there is no common notion of time in a wireless sensor network in which all the nodes are physically separated and no global clock or common memory exists. Moreover, there is no guarantee that the sensed data will get to the destination before the deadline. To address these real-time...

Time-of-day alarm once per second to once per day - End-of-clock update cycle ® 24-pin plastic DIP, SOIC, or SSOP General Description The CMOS bq3285E/L is a low- power microprocessor peripheral providing a time-of-day clock and 100-year calendar with alarm fea- tures and battery...
DS1307is a low power serial real time clock with full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM (Non Volatile Static Random Access Memory). Data and Address are transferred serially through a bidirectionalI2Cbus. The RTC provides year, month, date, hour, minute and...

ISL1219 ® Real Time Clock/Calendar with Event Detection Data Sheet August 14, 2006 FN6314.1 Low Power RTC with Battery Backed SRAM and Event Detection The ISL1219 device is a low power real time clock with Event Detect and Time Stamp function, timing and crystal compensation, clock/calendar...
The Real-Time Clock (RTC) is a hardware component that tracks wall clock time and is battery backed so it works even with system power off. Such clocks will normally not track the local time zone or daylight saving time but will instead be set to Coordinated Universal Time. ...
on every clock update (i.e., once per second); at periodic intervals with a frequency that can be set to any power-of-2 multiple in the range 2 Hz to 8192 Hz; on reaching a previously specified alarm time. Each of those interrupt sources can be enabled or disabled separately. On man...
