Product Overview

The DS1245W-100+ is a 3.3V 1024K non-volatile SRAM in 32 pin EDIP package. It is fully static, non-volatile SRAM organized as 131,072 words by 8bits. Each NV SRAM has a self contained lithium energy source and control circuitry which constantly monitors VCC for an out of tolerance condition. When such a condition occurs lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption. Device can be used in place of existing 128K x 8 static RAMs directly conforming to popular bytewide 32pin DIP standard. Device in the PowerCap Module package are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete non-volatile SRAM module. There is no limit on the number of write cycles that can be executed and no additional support circuitry is required for microprocessor interfacing.
  • Supply voltage range is 3V to 3.6V
  • Operating temperature range from 0°C to 70°C
  • Data is automatically protected during power loss
  • Replaces 128K x 8 volatile static RAM EEPROM or flash memory
  • Unlimited write cycles, low power CMOS
  • Read and write access times of 100ns
  • Lithium energy source is electrically disconnected to retain freshness
  • Replaceable snap-on PowerCap provides lithium backup battery
  • Standardized pinout for all non-volatile SRAM products
  • Detachment feature on PowerCap allows easy removal using a regular screwdriver
