L9963T is able to transfer munication data ining from a classical 4-wire based SPI interface to a 2-wire isolated interface (and viceversa). The transceiver supports both transformer and capacitive isolation, since the isolated signal generated according to a proprietary protocol is suitable to be transmitted over both decoupling circuitries. The device can be configured either as Slave or as Master of the SPI bus and supports any protocol made of SPI frames 8 to 64 bit long. The transceiver manages the transfer of the information without performing any protocol check. SPI peripheral can work up to 10 MHz when configured as Slave. SPI clock frequency can be programmed among (250 k Hz; 1 MHz; 4 MHz; 8 MHz) when configured as...
