Note:1.Absolute Maximum Ratings (1)
Note: 1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. 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.
CAUTION: Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.

DESCRIPTION
The M48T35/35Y TIMEKEEPER RAM is a 32Kb
x8 non-volatile static RAM and real time clock. The
monolithic chip is available in two special packag-
es to provide a highly integrated battery backed-up
memory and real time clock solution.
The M48T35/35Y is a non-volatile pin and function
equivalent to any JEDEC standard 32Kb x8
SRAM. It also easily fits into many ROM, EPROM,
and EEPROM sockets, providing the non-volatility
of PROMs without any requirement for special
write timing or limitations on the number of writes
that can be performed.
The 28 pin 600mil DIP CAPHAT houses the
M48T35/35Y silicon with a quartz crystal and a
long life lithium button cell in a single package.
The 28 pin 330mil SOIC provides sockets with
gold plated contacts at both ends for direct con-
