The TJA1054AT/S900M is an integrated transceiver designed for use in applications that require an interface between a Controller Area Network (CAN) protocol controller and physical two-wire CAN bus. With this transceiver, the controller can be interfaced directly to a two-wire CAN bus with a maximum data speed of 1 megabit per second (1Mb/s). This makes it suitable for both low-speed and high-speed CAN networks.

The TJA1054AT/S900M is a single-channel, open-drain CAN bus physical layer transceiver. It is designed to convert the CAN frames into signals suitable for data transmission over a two-wire bus. The TJA1054AT/S900M supports a single-wire low-speed CAN bus and a single-wire high-speed CAN bus. In addition, it also supports the NXP’s proprietary HDLC protocol for controlling power up and during power down.

The transceiver contains four stages: The transceiver’s input stage, the transmission/reception stages, and the output stage. The transceiver’s input stage receives the serial data stream from the CAN network and shapes the signal before being passed to the transmitter/receiver stages. The transmission/reception stages circulate signals in order to detect bus errors, frame mismatches, bit collisions, and incorrect signals. The output stage then transmits the bits onto the CAN bus.

The TJA1054AT/S900M offers two operating modes. In silent mode, the transceiver produces no output. This mode is used when the bus is placed in standby mode, when the bus is not operated or when it is not required to transmit or receive data. In active mode, the transceiver is enabled to transmit and receive data. In this mode, the transceiver produces an output based on the signals it receives from the input. The device also provides a fault detection and diagnostic feature for detecting possible errors.

The TJA1054AT/S900M is suitable for applications in the automotive, industrial, and consumer markets. Common applications include Automotive CAN bus networks, Factory automation and pharmaceutical equipment, Diagnostic and monitoring systems, Consumer devices, and so on. The device is designed to provide a reliable performance and to enable interoperability and communication between CAN nodes.

The TJA1054AT/S900M is an ideal solution for interfacing CAN controllers to two-wire CAN buses, as it is easy to interface and provides a reliable data link. The device is cost effective and is suitable for automotive and industrial applications, where reliable communication and data transmission is essential.
