3.3V, 8Mb, Nonvolatile SRAM with Clock

Includes All the Components Needed for a 1M x 8 Battery-Backed SRAM Module with a RTC in the Standard PowerCap Package

Please check latest availability status for a specific part variant.


The DS3065WP consists of a static RAM, a nonvolatile (NV) controller, and a real-time clock (RTC). These components are packaged on a surface-mount substrate and require post-assembly attachment of a DS9034IPCX+ battery cap. Whenever VCC is applied to the module, it powers the clock and SRAM from the external power source, and allows the contents of the clock registers or SRAM to be modified. When VCC is powered down or out of tolerance, the controller write protects the memory contents and powers the clock and SRAM from the battery.
