The TJF1051 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features ideal passive behavior to the CAN bus when the supply voltage is off. The TJF1051T/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V.

The TJF1051 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of ISO 11898-2:2016. Pending the release of the updated version of ISO11898-2:2016 including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delay symmetry are specified. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
These features make the TJF1051 an excellent choice for all types of HS-CAN networks, in nodes that do not require a standby mode with wake-up capability via the bus.

2. Features and benefits
2.1 General
- Fully ISO 11898-2:2003 compliant
- Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
- Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
- VIO input on the TJF1051T/3 allows for direct interfacing with 3 V to 5 V microcontrollers
- Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
2.2 Low-power management
- Functional behavior predictable under all supply conditions
- Transceiver disengages from the bus when not powered up (zero load)
2.3 Protection
- High ESD handling capability on the bus pins
- Transmit Data (TXD) dominant time-out function
- Undervoltage detection on pins VCC and VIO
- Thermally protected

The TJF1051 is a stand-alone high-speed CAN transceiver with Silent mode. It combines the functionality of the TJA1050 transceiver with improved EMC and ESD handling capability. Improved slope control and high DC handling capability on the bus pins provides additional application flexibility. The TJF1051T/3 allows for direct interfacing to microcontrollers with supply voltages down to 3 V.
