Pinout




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.DS1213C accepts a 32K x 8 JEDEC bytewide CMOS static RAM. When the DS1213C is mated with a CMOS RAM, it provides a complete solution o problems associated with memory volatility. The DS1213C 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 DS1213C 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.
