| FlexRayTM TRansceiveR Features y Part of the FlexRayTM electrical, physical layer y Interface between the communication controller and the transfer medium (twisted pair bus line) y Support of data rates up to 10 Mbit/s y Enhanced diagnosis capability provided via SPI with interrupt generation y Protection against overload damage by current limitation and overtemperature detection y Bus driver outputs withstand - 27 V / + 40 V DC voltage y Low EME due to balanced differential transmission E910.54 Brief Functional Description The low cost basic FlexRayTM transceiver is part of the electrical, physical layer in a FlexRayTM communication network. The E910.54 provides an interface between the twisted pair physical bus medium and a communication controller (CC). An SPI interface connects the bus driver (BD) to a host controller (HOST) to provide status information concerning failure detection on the bus lines (e.g. short-circuits, ground loss) and overtemperature condition. An interrupt signal is generated whenever the failure status changes. applications y Transceiver in FlexRayTM nodes (ECUs) ELMOS is member of the FlexRay consortium Typical application Blockdiagram SCSN Microcontroller (HOST) Communication Controller TxEN SPI INTN TxD RxD Power Supply ECU 1 SCK SDI SDO INTN RxD TxD Host Interface (SPI + Interrupt) Internal Logic Communication Controller Interface Power Supply Bus Failure Detector BP Transmitter BM 4 Receiver VIO VCC BP TxEN Bus Driver E910.54 BM VCC VIO Undervolt.
