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, RST , and DQ.
Nonvolatility can be achieved by connecting a battery of 2V to 4V at the battery input VBAT. A load of
0.5
mA should be used to size the external battery for the required data retention time. If nonvolatility is
not required the VBAT pin should be grounded.
16-Pin SO (300mil)
