DESCRIPTION
The DS1213B SmartSocket is a 28–pin, 600 mil DIP
socket with a built–in CMOS controller circuit and an
embedded lithium energy source. It accepts either
24–pin 2K x 8 (lower–justified) or 28–pin 8K x 8 JEDEC
bytewide CMOS static RAM. When the socket is mated
with a CMOS RAM, it provides a complete solution to
problems associated with memory volatility. The Smart-
Socket monitors incoming V
CC
for an out–of–tolerance
condition. When such a condition occurs, the internal
lithium energy source is automatically switched on and
write protection is unconditionally enabled to prevent
data corruption.
Using the SmartSocket saves printed circuit board
space since the SRAM/SmartSocket combination occu-
pies no more area than the SRAM alone. The Smart-
Socket modifies only pins 20, 26 and 28, to nonvolatize
the RAM. All other pins are passed straight through.
