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. The SmartWatch ROM sockets use the embedded lithium source to maintain the time and date only. A key feature of the SmartWatch is that the watch function remains transparent to the RAM. The SmartWatch monitors VCC for an out-of-tolerance condition. When such a condition occurs, an internal lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent loss of watch and RAM data.
FEATURES

Product Usage
The DS1216B is a SmartWatch RAM installed in DIP (Dual Inline Package) sockets that provide real-time clock (RTC) functionality to SRAM (Static Random Access Memory) without the need for external components or additional RTC ICs (Integrated Circuits). Due to its integration of a RTC in a socket form, it can be used in a variety of circuits.
Typical circuits that use the DS1216B include:
Embedded Systems:
Computing Systems:
Industrial Control Systems:
Consumer Electronics:
Data Logging and Time-stamping Devices:
Telecommunications Systems:
Test and Measurement Equipment:
When designing circuits with the DS1216B, typical considerations include:
However, note that many modern designs might prefer newer, more integrated RTC solutions over the DS1216B due to advancements in technology and the availability of smaller, more efficient RTC ICs.
