Product Details
| DESCRIPTION The DS1251 4096K NV SRAM with Phantom Clock is a fully static nonvolatile RAM (organized as 512K words by 8 bits) with a built-in real-time clock. The DS1251Y 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 Keeps Track of Hundredths Of Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years ■ 512K 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 ■ Over 10 Years of Data Retention in the Absence of Power ■ Full 10% Operating Range ■ 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 – Upward Compatible with the DS1248 ■ PowerCap Module Board Only − Surface Mountable Package for Direct Connection to PowerCap Containing Battery and Crystal − Replaceable Battery (PowerCap) − Pin-for-Pin Compatible with Other Densities of DS124xP Phantom Clocks |
