Description
SmartWatch RAM DS1216B/C/D/H SmartWatch ROM DS1216E/F
All product names, trademarks, brands and logos used on this site are the property of their respective owners.

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.
FEATURES

Wow, I see many people help give proposals to u, Utsource is really good to offer electronic components. as far as I know, e-nergie buys electronic components from Utsource and put those components into their unique kits, which is very convenient for engineers to pick out the values they want to have.
