DESCRIPTION
The M48T513Y/V TIMEKEEPER RAM is a
512 Kb x 8 non-volatile static RAM and real time
clock, with programmable alarms and a watchdog
timer. The special DIP package provides a fully in-
tegrated battery back-up memory and real time
clock solution. The M48T513Y/V directly replaces
industry standard 512 Kb x 8 SRAM. It also pro-
vides the non-volatility of Flash without any re-
quirement for special WRITE timing or limitations
on the number of WRITEs that can be performed.
For surface-mount environments ST provides a
solution consisting of a 44-pin, 330mil SOIC TIME-
KEEPER SUPERVISOR (M48T201V/Y) and a 32-
pin TSOP Type II (10 x 20mm) LPSRAM
(M68Z512/W) packages.
The 44-pin, 330mil SOIC provides sockets with
gold plated contacts at both ends for direct con-
nection to a separate SNAPHAT housing contain-
ing the battery.
The unique design allows the SNAPHAT battery
package to be mounted on top of the SOIC pack-
age after the completion of the surface-mount pro-
cess. Insertion of the SNAPHAT housing after
reflow prevents potential battery damage due to
the high temperatures required for device surface-
mounting. The SNAPHAT housing is keyed to pre-
vent reverse insertion.
The SNAPHAT battery package is shipped sepa-
rately in plastic anti-static tubes or in Tape & Reel
form. The part number is “M4Txx-BR12SH1” (see
Table 15, page 24).
