Features

Reflowable, 34-Pin PowerCap Package

Additional Details

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 V_CC 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 V_CC is powered down or out of tolerance, the controller write protects the memory contents and powers the clock and SRAM from the battery.
