M48Z35AY, M48Z35AV
SUMMARY DESCRIPTION
The M48Z35AY/V ZEROPOWER
Kbit x 8, non-volatile static RAM that integrates
power-fail deselect circuitry and battery control
logic on a single die. The monolithic chip is avail-
able in two special packages to provide a highly in-
tegrated battery backed-up memory solution.
The M48Z35AY/V is a non-volatile pin and func-
tion equivalent to any JEDEC standard 32K 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 M48Z35AY/V silicon
with a long life lithium button cell in a single pack-
age.

The 28-pin, 330mil SOIC provides sockets with
gold plated contacts at both ends for direct con-
nection to a separate SNAPHAT
taining the battery. The unique design allows the
SNAPHAT battery 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
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 sep-
arately in plastic anti-static tubes or in Tape & Reel
form.
For the 28-lead SOIC, the battery package (e.g.,
SNAPHAT) part number is “M4Z28-BR00SH1.”
