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
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
Full
±10% operating range
Operating temperature range 0
°C to 70°C
Accuracy is better than
±1 minute/month @
25
°C
