DESCRIPTION
The M48T559Y TIMEKEEPER
RAM is an 8K x 8
non-volatile static RAM and real time clock. The
monolithic chip is available in the SNAPHAT pack-
age to provide a highly integrated battery backed-
up memory and real time clock solution.
The 28 pin 330mil SOIC provides sockets with gold
plated contacts at both ends for direct connection
to a separate SNAPHAT housing containing the
battery and crystal. The unique design allows the
SNAPHAT battery package to be mounted on top
of the SOIC package after the completion of the
surface mount process.
