DESCRIPTION
The DS1216 SmartWatch RAM and SmartWatch ROM Sockets are 600mil-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. Using the SmartWatch saves PC board space since the combination of SmartWatch and the mated RAM take up no more area than the memory alone. The SmartWatch uses the VCC, data I/O 0, CE , OE , and WE for RAM and watch control. All other pins are passed straight through to the socket receptacle. The SmartWatch provides timekeeping information including hundredths of seconds, seconds, minutes, hours, days, date, months, and years. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including correction for leap years. The SmartWatch operates in either 24-hour or 12-hour format with an AM/PM indicator.

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 onvolatile
memory
· Embedded lithium energy cell maintains watch information and retains RAM data
· Watch function is transparent to RAM operation
· Month and year determine the number of days in each month; leap-year compensation valid
up to 2100
