DESCRIPTION
The DS1248 1024k NV SRAM with Phantom Clock is a fully static nonvolatile RAM (organized as 128k words by 8 bits) with a built-in real-time clock. The DS1248 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.
FEATURES
● Real-time clock (RTC) keeps track of hundredths of seconds, minutes, hours, days, date of the month, months, and years
● 128k 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
● Month and year determine the number of days in each month; valid up to 2100
● Full 10 operating range
● Operating temperature range: 0C to +70C
● 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 32-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 DS1244P and DS1251P
