UART-RF16550

The RF16550 is a standard UART providing 100% software compatibility with the Texas Instruments 16550 device. It performs serial-to-parallel conversion on data originating from modems or other serial devices, and performs parallel-to-serial conversion on data from a CPU to these devices.The 16550 can be run in either 16550-compatible character mode or in 16550-compatible FIFO mode, in which an internal FIFO relieves the CPU of excessive software overhead. Developed for easy reuse in Xilinx FPGA applications, the 16550 is available optimized for several device families with competitive utilization and performance characteristics.

• Serial or modem computer interface
   
• Serial interface within modems and other devices
   

Features

• Capable of running all existing 16550 and 16550a software
   
• In FIFO mode, the transmitter and receiver are each buffered with 16-byte FIFOs to reduce the number of interrupts presented to the CPU
   
• Adds or deletes standard asynchronous communication bits (start, stop and parity) to or from the serial data
   
• Independently controlled transmit, receive, line status and data set interrupts
   
• Programmable baud generator divides any input clock by 1 to (2¹⁶ - 1) and generates the 16x clock

RealFast is a member of the Common License Consortium. As a member, RealFast supports the SignOnce IP License for customers who wish to use any of our cores in Xilinx programmable logic devices. The SignOnce IP License represents a landmark accomplishment for the intellectual property (IP) industry. It is a set of standard terms being accepted by many of the industry's leading providers of soft IP cores for use in programmable logic. With this agreement, customers only have to review and execute one license to ease access to FPGA cores from multiple suppliers.
