CXPI Transceiver for Automotive - BD41000AFJ-C (New)

BD41000AFJ-C is a transceiver for the CXPI (Clock Extension Peripheral Interface) communication. Switching between Master/Slave Mode can be done using external pin (MS pin). Low power consumption during standby (non-communication) using Power Saving function. Arbitration function stops the data output upon detection of BUS data collision. Also Fail-safe function stops outputs upon detection of under voltage or temperature abnormality.
