DS1243Y - 64K NV SRAM

General Description

Active-Low Reset Input.

This pin has an internal pullup resistor connected to VCC.

Key Features

  • Real-Time Clock Keeps Track of Hundredths of Seconds, Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years.
  • 8K 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.
  • Lithium Energy Source is Electrically Disconnected to Retain Freshness Until Power is Applied for the F.
