is a multiprotocol UART/I2C serial interface integrated circuit (IC). The IC allows for communication between different devices via UART and I2C interfaces. It can be used to bridge communications between different types of clients, such as smartphones, PCs, and IoT devices. The IC comes in a 32-pin QFN package and is capable of operating over a temperature range of –40 to +85°C. Additionally, the IC features an interrupt status flag, a low-power standby mode, and adjustable data rate up to 4 Mbps. The IC also integrates an auto-flow control and has several communication settings that make it convenient to set up and use. It offers excellent signal integrity with high noise immunity and is capable of transmitting data over long distances.
