DS1250AB-70+

The DS1250AB-70+ is a 4096k non-volatile SRAM in 32 pin EDIP package. This fully static SRAM is organized as 524,288 words by 8 bits. Each complete NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out of tolerance condition. Whenever this condition occurs, the lithium energy source is automatically switched on and the write protection is unconditionally enabled to prevent data corruption. This device can be used in place of existing 512k x 8 static RAMs directly conforming to the popular byte-wide standard. It is normally paired with a DS9034PC PowerCap to form a complete non-volatile SRAM module and there is and no additional support circuitry required for microprocessor interfacing.
