Abstract — Typically, a variety of digital devices are built into the MCU. These digital devices in order to develop a variety of applications PC, various devices such as smart phones should be easily connected. But so far the interface of these devices has not been a unified approach. Development of various types of devices to easily shall be equipped with various interfaces such as UART, SPI, I2C. However, there follows a lot of hardware problems to greatly increasing the number of I/O ports. Universal I / O are four types based on the same port. Each port is controlled the software approach to operate UART, SPI, I2C, etc.
Keywords— MCU; Universal I/O; UART; I2C; SPI)
