FEATURES

摟

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

摟

Lithium energy source is electrically

disconnected to retain freshness until power is

applied for the first time
