DS1244规格书详情
DESCRIPTION
The DS1244 256K NV SRAM with a Phantom clock is a fully static nonvolatile RAM (NV SRAM) (organized as 32K words by 8 bits) with a built-in real-time clock. The DS1244 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 write 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
■ 32K 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 28-Pin JEDEC Pinout
■ PowerCap Module Board Only
– Surface Mountable Package for Direct Connection to PowerCap Containing Battery and Crystal
– Replaceable Battery (PowerCap)
– Pin-for-Pin Compatible with DS1248P and DS1251P
■ Underwriters Laboratories (UL) Recognized
