STMicroelectronics L9963T
L9963T is a general purpose SPI to isolated SPI transceiver intended to create a communication bridge between devices located into different voltage domains. L9963T is able to transfer communication data incoming 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.| Part No. | L9963T |

DESCRIPTION
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.
