ST68C554CJ68-F Overview
Alternatively, UART can be purchased in the cost-effective PLCC package.Transmission is carried out over 4 channels.Its uPs/uCs/Peripheral ICs use SERIAL IO/COMMUNICATION CONTROLLER, SERIAL.The configuration uses 68 terminations.During operation, it receives a voltage of 5V.As a means of communicating data, there are 4 serial I/Os available.This device is an integrated circuit with 68 pins.In order for the equipment to work for a long period of time, it should not be allowed to reach a temperature above 0°C.UART is recommended that the operating temperature does not exceed 70°C to ensure long-term, normal performance.A configuration of the chip is determined by its 68 pins.A mounting method of Surface Mount is used.By keeping the supply voltage below 5.5V, reliability can be guaranteed.In order to maintain reliability, the supply voltage should be kept above 2.97V.Providing power supplies of 3.3/5V makes it reliable and efficient for electronic designers.In addition, it has the capability of performing ALSO OPERATES AT 3.3V SUPPLY.
