DS1248P - 1024K NV SRAM

This page provides the datasheet information for the DS1248P, a member of the DS1248 1024K NV SRAM family.

Description

The DS1248 1024K NV SRAM with phantom clock is a fully static, nonvolatile RAM (organized as 128K words by 8 bits) with a built-in real-time clock.

The DS1248 has a self-contained lithium energy source and control circuitry, which constantly monitors VCC for an out-of-tolerance condition.

Features

  • Real-Time Clock (RTC) Keeps Track of Hundredths of Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years.
  • 128K x 8 NV SRAM Directly Replaces Volatile Static RAM or EEPROM.
  • Embedded Lithium Energy Cell Maintains Calendar Operation and Retains RAM Data.
  • Watch Function is Transparent to RAM Operation.
  • Automatic Leap Year Compensation Valid Up to 2100.
  • Full 10% Operating Range.
  • Over 10 Years of Data Retention in the Absence of Power.
  • Lithium Ene.
