Product Summary
The DS1248Y-100 is a fully static nonvolatile RAM (organized as 128k words by 8 bits) with a built-in real-time clock. The DS1248Y-100 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.
Parametrics
DS1248Y-100 absolute maximum ratings: (1)Voltage Range on Any Pin Relative to Ground: -0.3V to +6.0V; (2)Storage Temperature Range: -40 to +85℃; (3)Soldering Temperature Range: +260℃ for 10 seconds (DIP).
Features
DS1248Y-100 features: (1)Real-time clock (RTC) keeps track of hundredths of seconds, minutes, hours, days, date of the month, months, and years; (2)128k × 8 NV SRAM directly replaces volatile static RAM or EEPROM; (3)Embedded lithium energy cell maintains calendar operation and retains RAM data; (4)Watch function is transparent to RAM operation; (5)Month and year determine the number of days in each month; valid up to 2100; (6)Full 10% operating range; (7)Operating temperature range: 0 to +70℃; (8)Over 10 years of data retention in the absence of power; (9)Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time; (10)DIP Module only; (11)Standard 32-pin JEDEC pinout.
