DS1248YP-100

The DS1248YP-100 is designed as 1024K NV SRAM with Phantom Clock which is a fully static nonvolatile RAM (organized as 512K words by 8bits) with a builtin real time clock. DS1248YP-100 has a selfcontained lithium energy source and control circuitry which constantly monitors VCC for an outoftolerance condition.

DS1248YP-100 has many features. (1)Real time clock keeps track of hundredths of seconds, minutes, hours, days, date of the month, months, and years. (2)128Kx8 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°C to 70°C. (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. And so on.

Some absolute maximum ratings of DS1248YP-100 have been concluded as follow. (1)Its voltage on any pin relaive to ground would be from -0.5V to +7.0V. (2)Its operating temperature range would be from 0°C to 70°C. (3)Its storage temperature range would be from -40°C to +70°C. (4)Its soldering temperature would be 260°C for 10 seconds. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some DC electrical characteristics of DS1248YP-100 are concluded as follow. (1)Its input leakage current would be min -1.0uA and max +1.0uA. (2)Its IO leakage current would be min -1.0uA and max +1.0uA. (3)Its output current at 2.4V would be min -1.0mA. (4)Its output current at 0.4V would be min 2.0mA. (5)Its operating current tCYC=70ns would be max 85mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
