Info Validity Commence and End Definition Output Acknowledge

BYTE Generate: Pursuing a begin issue, a compose operationrequires a 7-bit info term deal with along with a reduced publish bit. Uponreceipt of the tackle, the EEPROM will all over again respondwith a zero then clock from the first 8-bit facts term. Fol-lowing receipt in the 8-bit information word, the EEPROM will out-put a zero and the addressing unit, these kinds of as amicrocontroller, have to terminate the compose sequence with astop issue.

Presently the EEPROM enters an inter-nally-timed write cycle on the nonvolatile memory. All inputsare disabled for the duration of this publish cycle , tWR, plus the EEPROMwill not react till the compose is total.

Web page Compose: The AT24C01 is capable of the 4-byte pagewrite.A web site write is initiated the same as a byte generate but themicrocontroller won't deliver a stop ailment right after the firstdata phrase is clocked in. In its place, soon after the EEPROMacknowledges receipt with the 1st information word, the microcon-troller can transmit as many as a few a lot more facts terms.

TheEEPROM will respond which has a zero soon after each and every data wordreceived. The microcontroller need to terminate the pagewrite sequence having a cease affliction.The information word handle decrease 2 bits are internally incre-mented next the receipt of each and every facts term.

The higherfive data phrase handle bits are certainly not incremented, retainingthe memory page row spot. In the event the term handle,internally generated, reaches the web page boundary, the fol-lowing byte is positioned in the beginning of the very same web page.

Ifmore than 4 information text are transmitted for the EEPROM,the information term handle will “roll over” and previous knowledge willbe overwritten.
