PIN ASSIGNMENT
PIN DESCRIPTION– Conditioned Chip Enable
VCC – Switched VCC
GND – GroundAll pins pass through except 20 and 28.
DESCRIPTIONThe 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 thesocket is mated with a CMOS RAM, it provides a complete solution o problems associated with memory
volatility. The SmartSocket monitors incoming VCC 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
occupies no more area than the memory alone. The SmartSocket 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.
