M48Z35AY, M48Z35AV

The M48Z35AY/35AV is a non-volatile pin and

function 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/35AV 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 housing contain-

ing 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.
