XR20M1172 -Dual Channel I2C/SPI UART With 64-Byte FIFO

1 The XR20M1172 (M1172) is a high performance two channel universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs 2 and a selectable I C/SPI slave Interface The M1172 operates from 1.62 to 3.63 volts. The standard features include 16 selectable TX and RX FIFO trigger levels, Automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control, and a complete modem Interface Onboard Registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. Additional enhanced features includes a programmable fractional baud rate generator and 8X and 4X sampling rate that allows for a maximum baud rate of 16 Mbps at 3.3V. The M1172 is available in the 32-pin QFN and 28-pin TSSOP packages. The 32- pin QFN package has the EN485# and ENIR# pins to allow the UART to power-up in the Auto RS485 mode or the Infrared mode.
