... ODW DATA RETENTION MODE The DS1250AB provides full functional capability for V 4.5 volts. The DS1250Y provides full functional capability for V protects by 4.25 volts. Data is maintained in the absence of V The nonvolatile static RAMs constantly monitor V automatically write protect themselves, all inputs become “don’t care,” and all outputs become high- impedance ...

... After a DS1250 PCM module base is reflow soldered, a DS9034PC PowerCap is snapped on top of the PCM to form a complete Nonvolatile SRAM module. The DS9034PC is keyed to prevent improper attachment. DS1250 module bases and DS9034PC PowerCaps are ordered separately and shipped in separate containers. See the DS9034PC data sheet for further information DS1250Y/AB ...
