Exar's XR20M1172 (M1172) and XR20V2172 (V2172) are high performance two-channel universal asynchronous receiver and transmitter (UART) ICs with 64 byte TX and RX FIFOs and a selectable I²C/SPI slave interface. The V2172 is also an RS232 transceiver. The V2172 operates from 2,97 to 3,63 V and the M1172 operates from 1,62 to 3,63 V. The M1172 is software compatible to the SC16CIS762/752, but with additional features such as a programmable fractional baud rate generator, wireless infrared (IrDA 1.0 and 1.1) encoder/decoder and 8X and 4X sampling rate that allows for a maximum baud rate of 16 Mbps at 3,3 V. The V2172 also includes a programmable fractional baud rate generator, an 8X and 4X sampling rate that allows for a maximum baud rate of 250 Kbps at 3.3V. The standard features for the M1172 and the V2172 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 operational status and data error flags. An internal loop-back capability allows system diagnostics.
