DESCRIPTION

The DS1270 16M Nonvolatile SRAMs are 16,777,216-bit, fully static nonvolatile SRAMs organized as

2,097,152 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control

circuitry which constantly monitors V_CCfor an out-of-tolerance condition. When such a condition occurs,

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

prevent data corruption. There is no limit on the number of write cycles which can be executed and no

additional support circuitry is required for microprocessor interfacing.
