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: 0 C to +70 C
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
PIN ASSIGNMENT
DS1248/DS1248P
