Product Description

GENERAL DESCRIPTION
The DS1216 SmartWatch RAM and SmartWatch ROM sockets are 600-mil-wide DIP sockets with a built-in CMOS watch function, an NV RAM controller circuit, and an embedded lithium energy
source. The sockets provide an NV RAM solution for memory sized from 2K x 8 to 512K x 8 with
package sizes from 26 pins to 32 pins. When a socket is mated with a CMOS SRAM, it provides a
complete solution to problems associated with memory volatility and uses a common energy source to maintain time and date.
FEATURES
 Keeps Track of Hundredths of Seconds, Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years
 Converts Standard 2K x 8 Up to 512K x 8 CMOS Static RAMs into Nonvolatile Memory
 Embedded Lithium Energy Cell Maintains Watch Information and Retains RAM Data
 Watch Function is Transparent to RAM Operation
 Automatic Leap Year Compensation Valid Up to 2100
 Lithium Energy Source is Electrically Disconnected to Retain Freshness Until Power is Applied for the First Time
 Proven Gas-Tight Socket Contacts
 Full ±10% Operating Range
 Accuracy Better Than ±1 Minute/Month at +25°C
