The TL16C752CI-Q1 is a dual universal asynchronous receiver transmitter (UART) with 64-byte FIFOs, automatic hardware and software flow control, and data rates up to 3 Mbps. The device offers enhanced features. It has a transmission Character control register (TCR) that stores received FIFO threshold level to start or stop transmission during hardware and software flow control.
