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.
