19-6075; Rev 11/11 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 complete solution to probl.

DS1217M Nonvolatile Read/Write Cartridge www.maxim-ic.com GENERAL DESCRIPTION The DS1217M is a nonvolatile RAM designed for portable applications requiring a rugged and durable package. The nonvolatile cartridge has memory capacities from 64k x 8 to 512k x 8. The cartridge is accessed in continuous 32k byte banks. Bank switching is accomplished under software control by pattern recognition from the address bus. A card edge connector is required for connection to a host system. A standard 30-pi.

SmartWatch RAM / SmartWatch ROM

19-6075; Rev 11/11 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 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. TYPICAL OPERATING CIRCUIT 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 RAM Operation  Automatic Leap Year Compensation Valid Up to 2100  Lithium Energy Source is Electrically Disconnected to Retain Fre.
