The XR20M1172IG28-F from Exar is a versatile two-channel UART designed for high-performance applications. It operates across a wide voltage range of 1.62V to 3.63V, making it suitable for various portable and battery-operated devices.
Key features include 64-byte transmit and receive FIFOs, 16 selectable FIFO trigger levels, and automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control. The device supports a selectable I2C/SPI slave interface with SPI clock frequencies up to 18 MHz at 3.3V. It offers data rates up to 16 Mbps at 3.3V and includes a fractional baud rate generator for precise timing.
Available in 28-pin TSSOP and 32-pin QFN packages, the XR20M1172IG28-F is designed for surface mount applications. Its capabilities extend to automatic RS-485 half-duplex direction control and wireless infrared encoding/decoding, making it a robust solution for factory automation, process controls, and cellular data devices.
