32K 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
