DESCRIPTION

The DS1330W 3.3V 256k Nonvolatile SRAM is a 262,144-bit, fully static, nonvolatile SRAM organized

as 32,768 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control

circuitry which constantly monitors V

the lithium energy source is automatically switched on and write protection is unconditionally enabled to

prevent data corruption. Additionally, the DS1330W has dedicated circuitry for monitoring the status of

are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete

Nonvolatile SRAM module. The devices can be used in place of 32k x 8 SRAM, EEPROM or Flash

components.
