AEK-COM-ISOSPI1 SPI to Isolated SPI Dongle

STMicroelectronics' AEK-COM-ISOSPI1 is an SPI to isolated SPI dongle, which allows converting SPI signals into isolated SPI signals, thereby reducing the number of necessary wires from four to two.

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.

Features

• Hosts the L9963T AEC-Q100 qualified automotive general purpose SPI to isolated SPI bidirectional transceiver
• Primary/secondary configuration through GPIOs or jumpers
• Four configurable pins for the SPI protocol
• Two configurable pins for amplitude and frequency of the converted signal (ISOSPI)
• Dimensions: 85 mm x 30 mm
