Interfacing baseline PIC MCUs with UNI/O bus-compatible serial EEPROMs

Posted: 01 May 2008 ?? ?Print Version ?Bookmark and Share

Keywords:MCU? EEPROM? I/O pin?

As embedded systems become smaller, a growing need exists to minimize I/O pin usage for communication between devices. Microchip has addressed this need by developing the UNI/O bus, a low-cost, easy-to-implement solution requiring only a single I/O pin for communication.

UNI/O bus-compatible devices can be used to enhance any application facing restrictions on available I/O. Such restrictions can potentially stem from connectors, board space or from the master device itself. The 11XXX family is the newest addition to Microchip Technology's broad serial EEPROM product line and is compatible with the newly developed UNI/O bus.

This application note is part of a series that provide source code to help the user implement the protocol with minimal effort.
