16Z025_UART - UART Controller IP Core
Overview
Diagram
Main Features
- FPGA IP Core
- Up to four independent UART channels
- Compatible to 16550 UART
- Wishbone bus interface
Description
The UART controller includes up to four 16550D compatible universal asynchronous receiver transmitter modules. The four channels of the quad UART are independent of each other. Each UART contains two FIFOs, one for transmitting and one for receiving data. Each FIFO has the extended size of 60 bytes. The eight FIFOs used in the four UARTs are combined in an internal RAM, an arbiter arbitrates the accesses of the four UART modules and the CPU interface. The Wishbone bus is used as the CPU interface.
