DS1248WP120IND

The DS1248WP120IND is one member of the DS1248WP family which is designed as the 1024k NV SRAM that has a self-contained lithium energy source and control circuitry, which constantly monitors VCC for an out-of-tolerance condition. Also this device is available in two packages: 32-pin DIP and 34-pin PowerCap module.

Features of the DS1248WP120IND are:(1)Real-time clock (RTC) keeps track of hundredths of seconds, minutes, hours, days, date of the month, months, and years; (2)128k x 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°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; (10)DIP Module only; (11)Standard 32-pin JEDEC pinout.

The absolute maximum ratings of the DS1248WP120IND can be summarized as:(1)Voltage on Any Pin Relative to Ground: -0.3 V to +6.0 V;(2)Operating Temperature: 0°C to 70°C;(3)Storage Temperature: -40°C to +85°C for IND parts;(4)Soldering Temperature: 260°C for 10 seconds.

The electrical characteristics of this device DS1248WP120IND can be summarized as:(1)Input Leakage Current: -1.0 to +1.0 V;(2)I/O Leakage Current CE VIH VCC: -1.0 to +1.0 A;(3)Output Current @ 2.2V: -1.0 mA;(4)Output Current @ 0.4V: 2.0 mA;(5)Standby Current CE =2.2V: 50 to 250 A;(6)Standby Current CE =VCC-0.2V: 30 to 150 A;(7)Operating Current: 50 mA;(8)Write Protection Voltage: 2.8 to 3.0 V.
