Module Introduction With the trend of miniaturization of the Embedded System, the minimization reqiurement of I/O Pin of Dvices’s communication is become higher and higher. The Microchip develops the Protocol Analyzer UNI/O which is low cost and easy to implement solutions; it only needs a I/O signal during the communication. The Protocol Analyzer UNI/O owns a main device and one or more than one auxiliary device; the MCU can serve as the main device, the other outside devices can serve as the auxiliary devices; the main device can only start the communication with one auxiliary device. Application Field It can be applied in the Serial EEPROM of the 11AAXXX/11LCXXX Series which is developed by the Microchip. 【DOWNLOAD】
