AEC-Q100

The STMicroelectronics L9963T series is a general purpose SPI to isolated SPI transceiver intended to create a communication bridge between devices located into different voltage domains. It is able to transfer communication data incoming from a classical 4-wire based SPI Interface to a 2-wire isolated Interface (and viceversa).

AEC-Q100 qualified

Full ISO26262 compliant, ASIL-D systems ready

Compatible with both 3.3 V and 5 V logics

Supports both XFMR and Capacitive isolation
