DESCRIPTION

The M48T35AY/35AV TIMEKEEPER® RAM is a

32Kb x8 non-volatile static RAM and real time

clock. The monolithic chip is available in two spe-

cial packages to provide a highly integrated bat-

tery backed-up memory and real time clock

solution.

The M48T35AY/35AV 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.
