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.
