XR16L580 UART

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.
