AutomaticPageWrite
Page-mode write feature allows 1 to128 bytes of data tobe writtenintothe EEPROMina single write cycle, and
allows theundefineddatawithin128bytes tobewrittencorrespondingtotheundefinedaddress (A0toA6). Loading
thefirstbyteofdata, thedataloadwindowopens30μsforthesecondbyte.Inthesamemannereachadditionalbyte
of data canbe loadedwithin30 μs. Incase CE andWE are kepthighfor100(s afterdata input, EEPROMenters
