Isolated Ports

These isolated ports are powered by an isolated DC-to-DC. It provides galvanic isolation
rated up to1500 VDC/second.
4.6.1

Isolated SPI

This interface is based on the trip-channel digital isolator ISO7231A. It has two channels,
one is in direction and the other channel is in opposition. The communication speed is up to
1Mbps.
4.6.2

Isolated UART

This interface is based on the ISO7221B which provides two isolation channels. The
channels are oriented in opposite directions. The communication speed is up to 5Mbps.
