Single-piece surface mount NVSRAM module has integrated realtime clock

16 November 2005 Electronics Technology

Dallas Semiconductor introduced what it claimed was the world's first and only single-piece, surface mountable nonvolatile SRAM modules with an integrated realtime clock (RTC).

The DS3030/DS3045/DS3050/DS3065 modules augment the company's existing NVSRAM module family (static RAM plus a NV controller). The 3,3 V modules provide a fully integrated and convenient method to protect critical data from unexpected and unscheduled power loss. Packaged in a 27 x 27 mm, 256-ball BGA, these parts are completely sealed from the outside environment.

The RTC contains a full-function, Y2K clock/calendar with an RTC alarm, watchdog timer, battery monitor, and power monitor. No additional support circuitry is required for microprocessor interfacing. The devices can be used in place of SRAM, EEPROM, or flash components.
