M48T37Y 采用5.0/3.3V,256Kbit(32Kbit × 8)计时器?SRAM

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).
