1. 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. 2. 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 nonvolatile memory > Embedded lithium energy cell maintains watch information and retains RAM data > Watch function is transparent to RAMoperation > Month and year determine the number of days in each month; leap-year compensation valid up to 2100 https://www.utsource.net/ic-datasheet/DS1216C-420488.html
