Reference Manual

RS-232 UART (HPS)

The development board supports two UART interfaces that connect to a mini-USB

connector (J27) using a FT232RQ-REEL USB-to-UART bridge. The maximum

supported rate for this interface is 1 Mbps. Board reference D21–D24 are the UART

LEDs that illuminate to indicate TX and RX activity.

Table 2–23 lists the RS-232 UART pin assignments, signal names, and functions. The

signal names and types are relative to the Arria V SoC in terms of I/O setting and

direction.
