Product Summary

The DS1216C is a SmartWatch RAM and SmartWatch ROM Socket. It is a 600mil-wide DIP socket 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 × 8 to 512k × 8 with package sizes from 26 pins to 32 pins. When a socket is mated with a CMOS SRAM, the DS1216C provides a complete solution to problems associated with memory volatility and uses a common energy source to maintain time and date.

Parametrics

DS1216C absolute maxing ratings: (1)Voltage Range on any Pin Relative to Ground: -0.3V to +7.0V for 5V; (2)Operating Temperature Range: 0℃ to +70℃; (3)Storage Temperature Range: -40℃ to +70℃.

Features

DS1216C features: (1)Keeps track of hundredths of seconds, seconds, minutes, hours, days, date of the month, months, and years; (2)Converts standard 2k× 8 up to 512k× 8 CMOS static RAMs into nonvolatile memory; (3)Embedded lithium energy cell maintains watch information and retains RAM data; (4)Watch function is transparent to RAM operation; (5)Month and year determine the number of days in each month; leap-year compensation valid up to 2100; (6)Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
