Additional Details:

The XR16C2850CM-0A-EB operates from a 3.3V or 5V power supply. It is available in a 64-pin QFP package. This device supports various interrupt modes, including FIFO trigger levels and modem status changes. The integrated RS-232 transceiver simplifies board design by eliminating the need for external level shifters. The device also features automatic hardware and software flow control, which helps to prevent data loss during high-speed communication. The large 96-byte FIFOs significantly reduce CPU overhead by allowing the UART to handle more data without requiring frequent processor intervention. It incorporates a programmable baud rate generator that supports a wide range of standard and custom baud rates. The internal loopback diagnostic capability enables easy testing and troubleshooting of the serial communication link. The full modem control signals facilitate communication with external modem devices. This UART is designed for reliable operation in harsh industrial environments and commercial applications.
