BD41001FJ-C CXPI Transceiver ROHM Semiconductor BD41001FJ-C CXPI Transceiver is an automotive device designed to reduce Electromagnetic interference (Electromagnetic Emission) noise of AM frequency band in comparison with BD41000AFJ-C. The BD41001FJ-C is a transceiver for the Clock Extension Peripheral Interface (CXPI) communication. This CXPI transceiver can be switched between master and slave mode using the external MS pin. The arbitration function of this device stops data output upon detection of BUS data collision. This BD41001FJ-C transceiver also includes fail-safe functions to stop outputs upon detection of under-voltage or temperature abnormality.
