XR16M770 1.62V to 3.63V Single UART with 64-Byte FIFO
The XR16M770¹ (M770) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with 64 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 16 Mbps at 3.3V, 12.5 Mbps at 2.5V and 8 Mbps at 1.8V with 4X data sampling rate. The Auto RS-485 Half-Duplex Direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. In addition, the Multidrop mode with Auto Address detection increases the performance by simplifying the software routines. The Independent TX/RX Baud Rate Generator feature allows the transmitter and receiver to operate at different baud rates. Power consumption of the M770 can be minimized by enabling the sleep mode and PowerSave mode.
