DS1216 SmartWatch RAM (DS1216B/C/D/H);
SmartWatch ROM (DS1216E/F)
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 plete solution to problems associated with memory volatility and uses a mon 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...
