Product validation according to AEC-Q100. Description FlexRay is a serial, deterministic bus system for real-time control applications. It is designed for future requirements of in-vehicle control applications, providing data transmission rates up to 10 Mbit/s. FlexRay is designed for collision-free data communication. The nodes do not arbitrate and the FlexRay Communication Controller (CC) guarantees a collision-free bus access during normal operation. Data Sheet 1 Rev. 1.31 www.infineon.com/automotive-transceiver 2019-02-06TLE9221SX FlexRay Transceiver Overview The TLE9221SX FlexRay transceiver is a FlexRay bus driver (BD) and it accomplishes the physical interface between the Communication Controller and the bus medium. Fully compliant with the FlexRay Electrical Physical Layer Specification, version 3.0.1 (acronym EPL) and ISO 17458. The TLE9221SX supports the following functional classes: Functional class bus driver voltage regulator control Functional class bus driver bus guardian interface Functional class bus driver logic level adaption Functional class bus driver remote wake-up The TLE9221SX supports data transmission rates from 1 Mbit/s up to 10 Mbit/s. Besides the transmit and receive capability of the bus, the TLE9221SX provides arrangements for low power supply management, supply voltage monitoring and bus failure detection. In BD Sleep mode, the TLE9221SX quiescent current decreases to a typical, total current consumption of 47.5 mA, while the device is still able to wake up by a dedicated wake-up pattern on the FlexRay data bus or by a local wake-up event on the pin WAKE. The INH output pin allows the control of external circuitry depending on the selected mode of operation. Fail-safe features, like bus failure detection or the power supply monitoring, combined with an easy accessible Status Information Register support the requirements of safety-related applications with extended diagnostic features. The TLE9221SX is internally protected against transients on all global pins. Global pins are BP, BM, WAKE and V . It is possible to use the TLE9221SX without any additional external protection circuitry while the BAT TLE9221SX meets the ESD and ISO pulse requirements of the car manufactures. The TLE9221SX is designed on the latest Infineon Smart Power Technology SPT, which combines power devices with a highly integrated logic process. Based on its digital design concept, the TLE9221SX provides very high immunity against RF disturbances over a wide frequency range. Based on the high symmetry of the BP and BM signals, the TLE9221SX provides the lowest level of electromagnetic emission (EME) within a wide frequency range. The TLE9221SX is integrated in a RoHS compliant PG-SSOP-16 package. The TLE9221SX and the Infineon Smart Power Technology SPT are especially tailored to withstand the harsh conditions of the automotive environment and qualified according to the AEC-Q100 standard.
