Additional Infomation About Product

XTAL2 XTAL1 XR20M1172 TWO CHANNEL I2C/SPI UART WITH 64-BYTE FIFO JULY 2018 REV. 1.2.1 FEATURES GENERAL DESCRIPTION 1.62 to 3.6 Volt Operation 1 The XR20M1172 is a high performance two channel 2 universal asynchronous receiver and transmitter Selectable I C/SPI Interface (UART) with 64 byte TX and RX FIFOs and a SPI clock frequency up to 2 selectable I C/SPI slave interface. The XR20M1172 18 MHz at 3.3 V operates from 1.62 to 3.63 volts. The standard features include 16 selectable TX and RX FIFO 16 MHz at 2.5 V trigger levels, automatic hardware (RTS/CTS) and 8 MHz at 1.8 V software (Xon/Xoff) flow control, and a complete Full-featured UART modem interface. Onboard registers provide the user with operational status and data error flags. An Data rate of up to 16 Mbps at 3.3 V internal loopback capability allows system Data rate of up to 12.5 Mbps at 2.5 V diagnostics. Additional enhanced features includes a Data rate of up to 8 Mbps at 1.8 V programmable fractional baud rate generator and 8X Fractional Baud Rate Generator and 4X sampling rate that allows for a maximum baud rate of 16 Mbps at 3.3V. The XR20M1172 is available Transmit and Receive FIFOs of 64 bytes in the 32-pin QFN and 28-pin TSSOP packages. The 16 Selectable TX and RX FIFO Trigger Levels 32-pin QFN package has the EN485 and ENIR Automatic Hardware (RTS/CTS) Flow Control pins to allow the UART to power-up in the Auto Automatic Software (Xon/Xoff) Flow Control RS485 mode or the Infrared mode.
