                                                ST16C554DIQ64TR-F Overview
Alternatively, UART can be purchased in the cost-effective LQFP package.In order to transmit data, there are 4 channels available.Packaging is based on Tape & Reel (TR).There is a SERIAL IO/COMMUNICATION CONTROLLER, SERIAL used as the type of uPS/uCs/peripheral ICs.Configured with 64 terminations.For its operation, it requires a supply voltage of 5V.In order to communicate data, there are 4 serial I/Os.There are a number of similarities between this piece and most of the other pieces in the subcategory Serial IO/Communication Controllers.UART is important to keep the operating temperature below -40°C to ensure a long working period.The operating temperature should be in excess of 85°C to ensure the normal work for a long time.Using the Surface Mount method, it is mounted.Keeping the supply voltage below 5.5V will ensure reliability.Having a voltage higher than 2.97V can ensure reliability.UART operates at a high efficiency due to the voltage supply of 5V.
