DS1213C数据手册集成电路（IC）的控制器规格书PDF

描述 Description

The DS1213C SmartSocket is a 28-pin, 600mil 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 solution of 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.
