Overview
XR20M1170 I2C/SPI UART with 64-Byte FIFO February 2, 2022 Rev.
1.
1.
3 GENERAL DESCRIPTION The XR20M11701 is a high performance universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs and a selectable I2C/SPI slave interface.
The XR20M1170 operates from 1.
62 to 3.
63 volts.
The enhanced features in the XR20M1170 include a programmable fractional baud rate generator, an 8X and 4X sampling rate that allows for a maximum baud rate of 16Mbps 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 XR20M1170 is available in the 24-pin QFN, 16-pin QFN, 24-pin TSSOP and 16pin TSSOP packages.
