DS1216
Manufacture:DALLAS
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.

I recently ordered an IC DS1216E from your company and I am very pleased with its performance. The IC is a high-performance, low-power device that is ideal for a wide range of applications. It provides excellent signal quality and is easy to use. The device is also very reliable and has a long life span. I am very satisfied with the performance of the IC and would highly recommend it to anyone loo
