Table 2. Absolute Maximum Ratings
(1)
Note: 1. Stresses greater than those listed under ”Absolute Maximum Ratings” may cause permanent damage to thedevice. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational section
of this specification is not implied. Exposure to the absolute maximum rating conditions for extended periods of time may affect
reliability.
2. Soldering temperature not to exceed 260
°
C for 10 seconds (total thermal budget not to exceed 150
°
C for longer than 30 seconds).
CAUTION:
Negative undershoots below –0.3V are not allowed on any pin while in the Battery Back-up mode.

DESCRIPTION
The M48T513Y/V TIMEKEEPER RAM is a 512Kb
x 8 non-volatile static RAM and real time clock,
with programmable alarms and a watchdog timer.
The special DIP package provides a fully integrat-
ed battery back-up memoryand realtime clock so-
lution. TheM48T513Y/V directly replaces industry
standard 512Kb x 8 SRAM. It also provides the
non-volatility of Flash without any requirement for
special write timingor limitations on the number of
writes that can be performed.

For surface mount environments ST provides a
Chip Set solution consisting of a 44 pin 330mil
SOIC TIMEKEEPER 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.
