The SJA1000T/N1,112 is an IC component widely used in automotive applications as a stand-alone controller in Local Interconnect Network (LIN) systems. It is designed to provide a flexible and efficient communication interface between a microcontroller and the LIN bus. Here is an overview of the key features of the SJA1000T/N1,112:
1. LIN Physical Interface: The SJA1000T/N1,112 supports a LIN 1.x physical interface, making it suitable for LIN bus communications. It provides a robust and reliable connection between the LIN master and slave devices.
2. Message Buffering: This IC component features a deep FIFO-based message buffer, capable of storing up to 32 receive and 8 transmit message frames. It ensures smooth and uninterrupted communication flow between the microcontroller and the LIN bus.
3. Extended Wake-Up Support: The SJA1000T/N1,112 supports extended wake-up functionality, allowing the device to automatically wake up from sleep mode upon receiving a LIN bus wake-up signal. This feature helps conserve power and ensures quick responsiveness when needed.
4. Integrated Timer Unit: It includes an integrated timer unit that provides timing functions required in LIN communication, such as synchronization and frame timing. This allows precise control over communication timings without relying solely on the microcontroller.
5. Error Detection and Handling: With built-in error detection and handling mechanisms, the SJA1000T/N1,112 ensures reliable communication
