DS1315S-33+

The DS1315S-33+ is a phantom time chip in 16 pin WSOIC package. The phantom time chip is a combination of a CMOS timekeeper and a non-volatile 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 such as 12hour mode with an AM/PM indicator or a 24hour mode. The non-volatile controller supplies all the necessary support circuitry to convert a CMOS RAM to a non-volatile memory. The DS1315 can be interfaced with either RAM or ROM without leaving gaps in memory.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from 0°C to 70°C
• Automatic leap year correction valid up to 2100
• No address space required to communicate with RTC
• Provides non-volatile controller functions for battery backup of SRAM
• Clock & Timing
