NXP Semiconductors N.V. debuts the TJA1048, a dual high-speed CAN transceiver that offers optimised performance and space solution targeted at automotive engine, body control and gateway applications that use multiple HS-CAN networks and require a low-power mode with wake-up capability via bus.

The TJA1048 features pin-to-pin compatibility with the single HS-CAN transceiver TJA1042/3 and offers high flexibility in building modular systems with either single or dual HS-CAN node.

Complementing NXP's High Performance Mixed Signal strategy, the TJA1048 caters to the automotive market need for space and cost effective solutions with excellent Electro Magnetic Compatibility (EMC) and Electrostatic Discharge (ESD) performance. By combining two independent third-generation HS-CAN transceivers into one package, and by sharing power supply and thermal protection, the TJA1048 supports very low power consumption for better energy efficiency and a more space efficient solution compared with two single transceivers.

The TJA1048 dual HS-CAN transceiver includes enhancements such as: 1) two TJA1042/3 HS-CAN transceivers combined monolithically in a single package; 2) very low-current Standby mode with bus wake-up capability on both channels; 3) ability to interface directly to microcontrollers with supply voltages from 3 to 5V; and 4) advanced low-power receiver to prevent unintended wake-up, as specified in ISO 11898-5.

Fully ISO 11898-2 and ISO 11898-5 compliant, the transceiver has been qualified to Automotive Electronics Council (AEC) standard Q100 and is suitable for use in automotive applications. Manufactured in SOI (silicon on insulator) technology, the TJA1048 has low emission and high immunity against electromagnetic interference meeting latest OEM requirements, while the bus pins are protected against transients in the automotive environment.

The TJA1048 SO14 is currently available in samples and volume production. TJA1048 HVSON14 is available for samples.
