FEATURES
Converts standard 8K x 8, 32K x 8, 128K x 8, and
512K x 8 CMOS static RAMs into nonvolatile memory
Embedded lithium energy cell maintains watch infor-
mation and retains RAM data
Watch function is transparent to RAM operation
Keeps track of hundredths of seconds, seconds, min-
utes, hours, days, date of the month, months, and
years
Month and year determine the number of days in each
month; leap year compensation valid up to 2100
Lithium energy source is electrically disconnected to
retain freshness until power is applied for the first time
Proven gas–tight socket contacts

DESCRIPTION
The DS1216D SmartWatch/RAM 256K/1M is a 32–pin,
600 MIL wide DIP socket with a built–in CMOS watch
function, a nonvolatile RAM controller circuit, and an
embedded lithium energy source. It accepts either an
8K x 8, 32K x 8, 128K x 8, or 512K x 8 JEDEC bytewide
CMOS static RAM. When the socket is mated with a
CMOS SRAM, it provides a complete solution to prob-
lems associated with memory volatility and uses a com-
mon energy source to maintain time and date. A key
feature of the SmartWatch is that the watch function re-
mains transparent to the RAM.
See the DS1216B SmartWatch/RAM 16/64K data sheet
for technical details.
