3.1.5 FSI

The F28P65x MCU features the Fast Serial Interface (FSI) communications peripheral. The FSI enables robust high-speed communications and is intended to increase the amount of information transmitted while reducing the cost to communicate over an isolation barrier. The FSI signals TXCLK, TXD0, TXD1, RXCLK, RXD0, and RXD1 are available on J11. This header is set up in such a way that adding jumpers on the pins connects the TX to RX channels for external loopback and evaluation. Additionally, there are two GND signals on the connector that can be used for a wrapped-pair connection to an external board with FSI. The GPIOs connected to this header are only routed to the J11 FSI connector on this board, the GPIOs are not routed to the boosterpack headers.

The LAUNCHXL-F28P65X does not include any on-board isolation devices for the FSI signals. If interested in evaluating the FSI peripheral with isolation devices, or differential drivers/receivers, see the TMDSFSIADAPEVM plug on board.
