TJA1057 - High-speed CAN transceiver

 

NXP

 

General Description

The TJA1057 is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.
The TJA1057 offers a feature set optimized for 12 V automotive applications, with significant improvements over first- and second-generation CAN transceivers from NXP, such as the TJA1050, and excellent electromagnetic compatibility (EMC) performance. The TJA1057 also displays ideal passive behavior to the CAN bus when the
supply voltage is off.
Variants with a VIO pin can be interfaced directly with microcontrollers with supply voltages from 3.3 V to 5 V.
The TJA1057 implements the CAN physical layer as defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5. The TJA1057T is specified for data rates up to 1 Mbit/s. Additional timing parameters defining loop delay symmetry are specified for the other variants. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. The TJA1057B and TJA1057C feature shorter propagation delay, supporting larger network topologies.
These features make the TJA1057 an excellent choice for HS-CAN networks that only require basic CAN functionality.

 

TJA1057은 Mantis 제품군의 고속 CAN 트랜시버 중 하나입니다. CAN(Controller Area Network) 프로토콜 컨트롤러와 물리적인 2선식 CAN 버스 간의 인터페이스를 제공합니다. 이 트랜시버는 자동차 산업의 고속 CAN 애플리케이션을 위해 설계되었으며, CAN 프로토콜 컨트롤러가 내장된 마이크로컨트롤러에 차동 송수신 기능을 제공합니다.
TJA1057은 12V 자동차 애플리케이션에 최적화된 기능을 제공하며, NXP의 1세대 및 2세대 CAN 트랜시버(예: TJA1050)에 비해 성능이 크게 향상되었고, 뛰어난 전자기 호환성(EMC) 성능을 자랑합니다. 또한, TJA1057은 전원 공급이 차단될 때 CAN 버스에 대해 이상적인 수동 동작을 나타냅니다.
VIO 핀이 있는 변형 제품은 3.3V~5V의 공급 전압을 사용하는 마이크로컨트롤러와 직접 인터페이스할 수 있습니다.
TJA1057은 ISO 11898-2:2024 3판 및 SAE J2284-1~SAE J2284-5에 정의된 CAN 물리 계층을 구현합니다. TJA1057T는 최대 1Mbit/s의 데이터 전송 속도를 지원합니다. 다른 변형 제품에 대해서는 루프 지연 대칭을 정의하는 추가 타이밍 파라미터가 명시되어 있습니다. 이 구현을 통해 최대 5Mbit/s의 데이터 전송 속도에서 CAN FD 고속 단계에서 안정적인 통신이 가능합니다. TJA1057B와 TJA1057C는 전파 지연이 더 짧아 더 큰 네트워크 토폴로지를 지원합니다.
이러한 특징 덕분에 TJA1057은 기본적인 CAN 기능만 필요한 HS-CAN 네트워크에 매우 적합합니다.
