DS1230YP-70+ Datasheet PDF - Maxim Integrated

The DS1230YP-70+ is a 256KB non-volatile SRAM in 34 pin PWRCP package. It is a 262,144 bit, fully static, non-volatile SRAM organized as 32,768 words by 8 bits. The 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, the lithium energy source is automatically switched on and the write protection is unconditionally enabled to prevent data corruption. The PowerCap Module (PCM) package is directly surface mountable module and replaceable snap on PowerCap provides lithium backup battery.
