DS1213B

SmartSocket 16k/64k


Please check latest availability status for a specific part variant.

Description

The DS1213B SmartSocket is a 28-pin, 600mil 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 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 SRAM alone. The SmartSocket modifies only pins 20, 26, and 28 to nonvolatize the RAM. All other pins are passed straight through.

Key Features

  • Accepts standard 2k x 8 or 8k x 8 CMOS static RAMs
  • Embedded lithium energy cell retains RAM data
  • Self-contained circuitry safeguards data
  • Data retention time is greater than 10 years with proper RAM selection
  • IC socket permits upgrading from 2k x 8 to 8k RAM
  • Proven gas-tight socket contacts
  • Operating temperature range 0°C to 70°C
