Description
The DS1315 Phantom Time Chip is a combination of a CMOS timekeeper and a nonvolatile memory controller. In the absence of power, an external battery maintains the timekeeping operation and provides power for a CMOS static RAM. The watch keeps track of hundredths of seconds, seconds, minutes, hours, day, date, month, and year information. The last day of the month is automatically adjusted for months with fewer than 31 days, including leap year correction. The watch operates in one of two formats: a 12-hour mode with an AM/PM indicator or a 24-hour mode. The nonvolatile controller supplies all the necessary support circuitry to convert a CMOS RAM to a nonvolatile memory. The DS1315 can be interfaced with either RAM or ROM without leaving gaps in memory.

Comparison
AdvantagesThe DS1315 Phantom Time Chip offers the following advantages:
- Accurate timekeeping with tracking of hundredths of seconds
- Automatic leap year correction up to 2100
- No address space required to communicate with RTC
- Nonvolatile controller functions for battery backup of SRAM
- Supports redundant battery attachment for high-reliability applications
- Operates in a wide voltage range of ±10% VCC
- Compatible with +3.3V or +5V operation
DisadvantagesOne potential disadvantage of the DS1315 Phantom Time Chip is its operating temperature range, which is limited to industrial environments ranging from -40°C to +85°C. It may not be suitable for applications exposed to extreme temperature conditions outside this range.
