Interfacing a serial EEPROM to a controller can be a
confusing task, especially for first time users. Because
communication with a parallel memory device is more
straightforward, the advantages of serial devices are
sometimes overlooked because of the time required to
learn a different protocol. In order to minimize this time,
Microchip provides many application notes on how to
interface a controller to our serial memory products.
Since every application is different, questions on differ-ent aspects of serial memories still arise. This applica-tion note provides answers to some of these commonly
asked questions on using serial EEPROMs. This series
of questions and answers covers a broad range of topics
concerning both 2-wire and 3-wire serial EEPROMS,
and covers material and/or circumstances that may not
be provided in the data book. Questions and Answers Concerning Serial EEPROMs

Questions and Answers Concerning Serial EEPROMs
Interfacing a serial EEPROM to a controller can be a Q: I’m using an interrupt routine in my controller code
confusing task, especially for first time users. Because that may leave the serial EEPROM in the middle of
communication with a parallel memory device is more a read command. When I return from the interrupt,
straightforward, the advantages of serial devices are is there any way to reset the part to make sure it is
