SCC2681AE1N28 Overview
Alternatively, UART can be purchased in the cost-effective PDIP package.Transmission is carried out over 2 channels.Its uPs/uCs/Peripheral ICs use SERIAL IO/COMMUNICATION CONTROLLER, SERIAL.The configuration uses 28 terminations.During operation, it receives a voltage of 5V.As a means of communicating data, there are 2 serial I/Os available.This device is an integrated circuit with 28 pins.Its clock frequency is measured at 4MHz.In order for the equipment to work for a long period of time, it should not be allowed to reach a temperature above -40°C.UART is recommended that the operating temperature does not exceed 85°C to ensure long-term, normal performance.By keeping the supply voltage below 5.5V, reliability can be guaranteed.In order to maintain reliability, the supply voltage should be kept above 4.5V.Providing power supplies of 5V makes it reliable and efficient for electronic designers.To ensure its high efficiency, a voltage of 5V is provided as the supply voltage.
