Description

The Compact UART will give you UART (Universal Asynchronous Receiver Transmitter) functionality with a minimum of space requirements. The Compact UART is fully LPM parameterizable and will never waste space on unused functionality. With the Compart UART, you may build UARTs of any word length. How about a 49-bit UART with 7 stop bits? With Compact UART, that is your decision.

Shown below is a sample schematic using the cuart_tx and cuart_rx modules, suitable for interfacing to a 8 bit microprocessor:
