The XR16L580 UART is currently one of the smallest UART devices. You will find these in a number of portable devices on the market such as handheld devices. If you are having problems, then see the most common UART problems which you might find. This UART uses the RS232 and RS422 protocols and these are a number of versions for the UART on the market. This all comes with a good data rate.
XR16L580 UART
Firstly the XR16L580 UART is manufactured by MaxLinear and there are a number of variations. Secondly they all offer the same data rates 
with a maximum at 3.125Mbps. Thirdly they also comes with the same voltage as well. Finally the IC’s all offer auto flow control as well as IrDA Encoder/Decoder as well as False Start Bit Detection and modem control. All of them are also surface mounted.
Firstly the UART comes with a 2.25V to 5.5V supply voltage as well as having a 5V tolerant inputs (except XTAL1) all of this on the Intel/Motorola bus select. Secondly there is a 16-byte Transmit FIFO as well as a 16-byte Receive FIFO with error flags with automatic hardware (RTS/CTS) flow control. Finally there are small packages: 24-QFN (4x4x0.9mm) as well as the 32-QFN (5x5x0.9mm) size option. Likewise see also the ft231x usb uart driver on here.

You will note that the XR16L580IL-F likewise features a small UART with a 16-byte Tx and Rx FIFOs. You will note that this is also supported by the Intel and Motorola buses. Likewise there is also a power save functionality.
Lastly also note that it is equipped with an internal oscillator. Likewise there was also a Timer/Counter. Note that this device functions on the voltage supply range of 2.25V to 5.5V. Likewise this was designed for surface mounting (SMD/SMT) applications. Lastly there was also a 32-VFQFN Exposed Pad. These are the features of the XR16L580 UART.
You will also note that there is one UART channel. This comes with the auto flow control function. The XR16L580IL-F also comes with a 16-byte FIFO as well as the IrDA encoder/decoder. There is also support for different protocols . These would include RS232 as well as the RS422. Lastly it also includes features such as false start bit detection and a memory size of 16 B.
Finally this is a very versatile product. Likewise it also offers a maximum data rate of 3.125Mbps. This includes the modem control and comes with a 32-QFN (5×5) supplier package. This makes is a valuable component for applications requiring reliable communication. Likewise see also the cp2102n driver on here as well as the bgm220sc12wga2 . Likewise the XR16L580 UART is explained further.
