HPS UART Controller Differences

The HPS includes two 16550-compatible UART controllers to provide asynchronous serial communications. The UARTs support 16750-compatible automatic flow control.

UART Controller Feature Cyclone V SoC Arria V SoC Arria 10 SoC Stratix 10 SoC
Synopsys IP Version 3.11a 3.11a 3.14b 3.15a
16550-compatible Yes Yes Yes Yes
Real-time clock flow trigger control No No Yes Yes

The UART controller uses two separate trigger levels for a DMA request and handshake signal to maximize throughput on the interface.
