DESCRIPTION  
FEATURES  
The DS1315 Phantom Time Chip is a Real-Time Clock Keeps Track of Hundredths  
combination of a CMOS timekeeper and a  
nonvolatile memory controller. In the absence of  
of Seconds, Seconds, Minutes, Hours, Days,  
Date of the Month, Months, and Years  
power, an external battery maintains the Adjusts for Months with Fewer than 31 Days  
timekeeping operation and provides power for a Automatic Leap Year Correction Valid Up to  
CMOS static RAM. The watch keeps track of  
hundredths of seconds, seconds, minutes, hours, No Address Space Required to Communicate  
day, date, month, and year information. The last with RTC  
day of the month is automatically adjusted for Provides Nonvolatile Controller Functions for  
months with less than 31 days, including leap Battery Backup of SRAM  
year correction. The watch operates in one of two Supports Redundant Battery Attachment for  
formats: a 12-hour mode with an AM/PM High-Reliability Applications  
2100  
indicator or a 24-hour mode. The nonvolatile Full ±10% VCC Operating Range  
controller supplies all the necessary support +3.3V or +5V Operation  
circuitry to convert a CMOS RAM to a Industrial (–45°C to +85°C) Operating  
nonvolatile memory. The DS1315 can be  
Temperature Ranges Available  
interfaced with either RAM or ROM without Drop-In Replacement for DS1215  
leaving gaps in memory.
