Summary description
The M48T37Y/V TIMEKEEPER RAM is a 32 Kb x8 non-volatile static RAM and real time
clock. The monolithic chip is available in a special package which provides a highly
integrated battery backed-up memory and real time clock solution.
The 44-lead, 330mil SOIC package 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/crystal package to be mounted on top of
the SOIC package after the completion of the surface mount process.
Insertion of the SNAPHAT housing after reflow prevents potential battery and crystal
damage due to the high temperatures required for device surface-mounting. The SNAPHAT
housing is keyed to prevent reverse insertion.
The SOIC and battery packages are shipped separately in plastic anti-static tubes or in
Tape &Reel form. For the 44-lead SOIC, the battery/crystal package (e.g., SNAPHAT) part
number is “M4T28-BR12SH” or “M4T32-BR12SH” (see Table 18 on page 27).
Caution:
Do not place the SNAPHAT battery/crystal top in conductive foam, as this will drain the
lithium button-cell battery.
