XR20M1172 - TWO CHANNEL I2C/SPI UART

Description

The XR20M11721 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.

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 XR20M1172 is available in the 32-pin.
