DESCRIPTION
The DS1213C SmartSocket is a 28–pin, 600 mil DIP
socket with a built–in CMOS controller circuit and an
embedded lithium energy source. It accepts a 32K x 8
JEDEC bytewide CMOS static RAM. When the socket
is mated with a CMOS RAM, it provides a complete so-
lution to problems associated with memory volatility.
The SmartSocket 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 memory alone. The Smart-
Socket uses only Pins 20 and 28 for RAM control. All
other pins are passed straight through.
See the DS1213B SmartSocket data sheet for technical
details.
