Product Description
The TJA1057 is part of the Mantis family of high-speed CAN transceivers.
It provides an interfaceinterface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.
two-wire CAN bus.
The transceiver is designed for high-speed CAN applications in the automotiveautomotive applications and provides the differential transmit and receive capability for (a) microcontroller with amicrocontroller with a CAN protocol controller.
Key features- Fully compliant with ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14- Optimized for use in 12 V automotive systems- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI),in accordance with the proposed EMC standards IEC 62228-3 and SAE J2962-2- AEC-Q100 qualified- Dark green product (halogen-free and RoHS (Restriction of Hazardous Substances)compliant)- Shorter propagation delay for TJA1057B and TJA1057C variants supports larger network topologies (see table 8)network topologies (see Table 8)- Variants with a VIO pin enable the direct connection of 3.3 V to 5 V microcontrollers.
Variants without a VIO pin can be connected to 3.3 V and 5 V-powered microcontrollers,provided that the I/Os of the microcontroller are 5 V tolerant.
The TJA1057 offers a feature set optimized for 12 V automotive applications, withwith significant improvements over NXP's first and second generation CAN transceivers,such as the TJA1050, as well as excellent electromagnetic compatibility (EMC).
The TJA1057 also exhibits ideal passive behavior to the CAN bus when the supply voltagevoltage is switched off.
Variants with a VIO pin can be connected directly to microcontrollers with supply voltagesSupply voltages from 3.3 V to 5 V.
The TJA1057 implements the CAN physical layer as defined in ISO 11898-2:2016 andSAE J2284-1 to SAE J2284-5.
The TJA1057T is specified for data rates up to 1 Mbit/s.
Additional timing parameters are specified for the other variants, which specify the symmetry of the loop delayvariants are specified.
This implementation enables reliable communication in the fast phase of CAN FDat data rates of up to 5 Mbit/s.
The TJA1057B and the TJA1057C have a shorter propagationpropagation delay and support larger network topologies.
These features make the TJA1057 an excellent choice for HS-CAN networks that only require basic CAN functionality.
basic CAN functionality.
