Description



The XR20M1172¹ (M1172) is a high performance two channel universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs and a selectable I²C/SPI slave interface. The XR20M1172 operates from 1.62 to 3.63 volts. It is software compatible to the SC16CIS762/752, but with additional features such as 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 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. The M1172 is available in the 32-pin QFN, 28-pin TSSOP and 20-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.
