AEK-COM-ISOSPI1

AEK-COM-ISOSPI1 is a SPI to isolated SPI dongle, which allows converting SPI signals in isolated SPI signals, thereby reducing the number of necessary wires from 4 to 2. The ISOSPI protocol features differential communication to ensure higher noise immunity and robustness for long distance communications. As the ISOSPI signals can travel for several meters, this protocol is particularly suitable for automotive high voltage applications where electrical isolation is required by the safety standards and the cable length can affect the communication among devices located in distant parts of the vehicle. The AEK-COM-ISOSPI1 is based on the L9963T general purpose SPI to isolated SPI bi-directional transceiver, which can transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface (and vice versa).

• Hosts the L9963T AEC-Q100 qualified general purpose SPI to isolated SPI bi-directional transceiver
• Host/ server configuration through GPIOs or jumpers
• 4 configurable pins for the SPI protocol
• 2 configurable pins for amplitude and frequency of the converted signal (ISOSPI)
• Dimensions: 85mm x 30mm
• Included in the AutoDevKit ecosystem
