DS1248P規(guī)格書詳情
DETAILED 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. When such a condition occurs, the lithium energy source is automatically switched on and writes protection is unconditionally enabled to prevent garbled data in both the memory and real-time clock.
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 Energy Source is Electrically Disconnected to Retain Freshness Until Power is Applied for the First Time
● DIP Module Only Standard 32-Pin JEDEC Pinout
