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
