Overview
The TL16C750EPFBR is a universal asynchronous receiver-transmitter (UART) device produced by Texas Instruments. It is an enhanced version of the TL16C750, offering advanced features such as 128-byte FIFOs for both transmit and receive operations, fractional baud rate support, and automatic hardware and software flow control. This device is designed to relieve the CPU of excessive software overhead by buffering received and transmitted characters, making it highly efficient in serial communication applications.
