... Optional industrial temperature range of -40°C to +85°C, designated IND DESCRIPTION The DS1220AB and DS1220AD 16k Nonvolatile SRAMs are 16,384-bit, fully static, nonvolatile SRAMs organized as 2048 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors V occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption ...

... OE WRITE MODE The DS1220AB and DS1220AD execute a write cycle whenever the WE and CE signals are active (low) after address inputs are stable. The latter occurring falling edge will determine the start of the write cycle. The write cycle is terminated by the earlier rising edge All address inputs must be kept valid throughout the write cycle ...
