FlexRay transceiver range extended
With the introduction of the new transceivers – TJA1083, TJA1085 and TJA1086 – NXP claims to deliver the industry’s most comprehensive portfolio of FlexRay transceivers to the automotive market. The TJA1083 is a FlexRay “clamp 15” node transceiver in a compact TSSOP14 package, while the TJA1085 and TJA1086 are both FlexRay active star couplers. The TJA1085 offers four branches, while the TJA1086 comes with two – both in a leadless HVQFN44 package with wettable flanks. All three transceivers deliver a significant improvement in EMC performance, providing 48V board net support and gap-free specification. With gap-free specification, the behaviour of the transceiver is specified over the full voltage for each supply down to the undervoltage detection level.
NXP says it regards FlexRay not as a successor, but as a natural functional extension to CAN-based systems and ideal for safety-relevant applications such as ADAS, chassis and power-train sensors, enabling communication with the ECU in a fast, reliable and deterministic manner. Within the automotive data networking technologies spectrum, the new transceivers complement other high-speed technologies such as Ethernet, which are better suited to infotainment applications. Furthermore, the faster rate of data exchange (10Mbps) that FlexRay enables between ECUs also means that the vehicle is more responsive, and can deliver more efficient fuel consumption and a reduction in CO2 emissions.
Like NXP’s entire FlexRay portfolio, the chips are compliant with JASPAR and EPL 3.0.1 certifications.
