TL16C550C.pdf: 完美自动流控UART收发器

The TL16C550C is a highly advanced UART transceiver, offering a wide range of features for asynchronous communication. One key feature is the programmable Auto-RTS and Auto-CTS capabilities, which allow for automatic flow control. In Auto-CTS mode, the Clear-To-Send (CTS) line controls the transmitter, while in Auto-RTS mode, the Ready-To-Send (RTS) line is controlled by the Receive FIFO contents and threshold settings. Furthermore, the TL16C550C includes serial and modem control outputs that are capable of directly driving a RJ11 cable when connected to equipment on the same power drop. This simplifies the setup process and ensures reliable communication. Additionally, this UART transceiver is compatible with all existing TL16C450 software, making it easy to integrate into existing systems. The TL16C550C supports clock rates of up to 16 MHz, allowing for operation at speeds of up to 1 Mbps. This high-speed operation is crucial for applications that require rapid data transfer. After a reset, all registers on the TL16C550C are identical to those of the TL16C450, simplifying the transition between different UART transceivers. In conclusion, the TL16C550C is a versatile and powerful UART transceiver, ideal for applications that require high-speed asynchronous communication with reliable flow control. Its programmable features, compatibility with existing software, and high clock rates make it a top choice for designers looking to implement robust communication solutions.
