The DS1245W-150+ 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 150ns
Lithium energy source is electrically disconnected to retain freshness
