256Kb Bytewide FRAM W/ Real-Time Clock

The FM3808 combines a 256Kb FRAM array with a M Real-Time Clock and a system supervisor function. An external 32.768 kHz crystal drives the timekeeping O function. It maintains time and date settings in the absence of system power through the use of a backup C battery power source. Data in the memory array does E not depend on the backup source, it remains W nonvolatile in FRAM. In addition to timekeeping, the R FM3808 includes a system supervisor to manage low E VDD power conditions and a watchdog Timer function. T N e B A programmable interrupt output pin allows the user to select the supervisor functions and the polarity of O R im the signal. N ir Ot T D F s By Ramtron Corporation
