5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs

The SC16C752B is a dual Universal Asynchronous Receiver/Transmitter (UART) with 64-byte FIFOs, automatic hardware/software flow control, and data rates up to 5 Mbit/s (3.3 V and 5 V). The SC16C752B offers enhanced features. It has a Transmission Control Register (TCR) that stores receiver FIFO thres Pin compatible with SC16C2550 with additional enhancements\nUp to 5 Mbit/s baud rate (at 3.3 V and 5 V; at 2.5 V maximum baud rate is 3 Mbit/s)\n64-byte transmit FIFO\n64-byte receive FIFO with error flags\nProgrammable and selectable transmit and receive FIFO trigger levels for DMA and interrupt ge;
