XR20M1280 Datasheet I2c/spi Uart

Manufacturer: Exar (now MaxLinear)

Overview: XR20M1280 I2C/SPI UART WITH 128-BYTE FIFO AND INTEGRATED LEVEL SHIFTERS MAY 2011 REV. 1.0.

General Description

The XR20M12801 (M1280) is a single-channel I2C/ SPI Universal Asynchronous Receiver and Transmitter (UART) with integrated level shifters and 128 bytes of transmit and receive FIFOs.

For flexibility in a mixed voltage environment, the M1280 has 4 VCC pins.

There is a VCC pin for the core, a VCC pin for the UART signals, a VCC pin for the CPU interface signals and a VCC pin for the GPIO signals.

Key Features

  • increase the performance by simplifying the software routines. The Independent TX/RX Baud Rate Generator feature allows the transmitter and receiver to operate at different baud rates. In addition, the Fractional Baud Rate Generator feature provides flexibility for crystal/clock frequencies for generating standard and non-standard baud rates. The M1280 has programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 24 Mbps. Power c.
