MIKROE-6778

MIKROE-6778 is a 2-wire SPI ISO click compact add-on board that provides a galvanically isolated communication bridge between devices operating in different voltage domains, enabling SPI data transfer across isolation barriers. It is based on L9963T, an automotive general-purpose SPI to isolated SPI transceiver. The board allows conversion between a standard 4-wire SPI and a proprietary 2-wire isolated SPI interface, supporting both transformer and capacitive isolation. It can be configured as either host or server, with support for SPI frames from 8 to 64bits, clock frequencies up to 10MHz in server mode, and programmable clock options in host mode. The isolated side features selectable operating speeds of 333kbps or 2.66Mbps, while internal buffering ensures smooth data flow across asynchronous domains. This Click board™ is ideal for automotive 48V and high-voltage systems, backup energy storage, UPS, industrial networks, remote sensors, and portable equipment.
