Description

The DS1200 serial RAM chip is a miniature read/write memory that can randomly access individual 8-bit strings (bytes) or sequentially access the entire 1024-bit contents (burst). Interface cost to a microprocessor is minimized by on-chip circuitry, which permits data transfers with only three signals: CLK, active-low RST, and DQ.

Nonvolatility can be achieved by connecting a battery of 2V to 4V at the battery input V_BAT. A load of 0.5µA should be used to size the external battery for the required data retention time. If nonvolatility is not required the V_BAT pin should be grounded.
