XR20V2172 Dual Channel I²C/SPI UART with 64-Byte FIFO and Integrated RS-232 Transceiver
The XR20V2172¹ (V2170) is a high performance universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs, a selectable I²C/SPI slave interface and RS232 transceiver. The V2170 operates from 2.25 to 3.63 volts. It is software compatible to the SC16CIS760/750/740, 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 1 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 V2170 is available in the 40-pin QFN.
