Typical Operating Circuit

General Description

The DS3065WP consists of a static RAM, a nonvolatile

(NV) controller, and a real-time clock (RTC). These com-

ponents are packaged on a surface-mount substrate

and require post-assembly attachment of a DS9034I-

module, it powers the clock and SRAM from the external

power source, and allows the contents of the clock reg-

down or out of tolerance, the controller write protects the

memory contents and powers the clock and SRAM from

the battery.
