Product Summary

The DS1216C is a SmartWatch RAM. It is a 600-mil-wide DIP socket with a built-in CMOS watch function, an NV RAM controller circuit, and an embedded lithium energysource. The DS1216C provides 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, the DS1216C acompletes solution to problems associated with memory volatility and uses a common energysource to maintain time and date. The DS1216C uses the embedded lithium source tomaintain the time and date only. A key feature of the SmartWatch is that the watch function remainstransparent to the RAM. The SmartWatch monitorsVCC for an out-of-tolerance condition. When such acondition occurs, an internal lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent loss of watchand RAM data.

Parametrics

DS1216C absolute maximum ratings: (1)Voltage Range on any Pin Relative to Ground: -0.3V to +6.0V; (2)Operating Temperature Range: 0℃ to +70℃; (3)Storage Temperature Range: -40℃ to +85℃; (4)Lead Temperature (soldering,10s): +260℃.

Features

DS1216C features: (1)Converts Standard 2K x 8 Up to 512K x 8; (2)CMOS Static RAMs into Nonvolatile Memory; (3)Embedded Lithium Energy Cell Maintains Watch Information and Retains RAM Data Watch Function is Transparent to RAM Operation.
