The TJA1028TK/5V0/20/X is an integrated circuit developed by NXP Semiconductors that provides bus systems with electrical communications capabilities. The device is used in applications such as automotive, instrumentation, industrial automation and home automation. It is used to communicate serial communication interface (SCI) signals via a physical medium like CAN bus or LIN bus.

The TJA1028TK/5V0/20/X is an integrated circuit Enhanced Single-Wire CAN Transceiver (ESCAN) component. It is designed to be used primarily in multi-drop networks like CAN bus, where high data rates must be communicated over a long distance. The component provides low-power operational modes, wide-operating temperature range, fault-tolerant features, and low electromagnetic interference (EMI) capability.

The circuit is designed to allow the transmission of digital data signals over distances of up to 60 meters. The component operates on a single supply voltage in the range of 4.5V to 5.5V and can be connected to the nodes in the network using a single twisted pair of wires. It supports a data rate of up to 1Mbps, with a maximum data rate of 10 Mbps.

The TJA1028TK/5V0/20/X device contains a voltage regulator, an over-temperature protection function, and a low-voltage level shift driver, which is used to convert the logic levels of the various nodes on the bus. It also has an internal transceiver that contains a differential-input receiver and a single-ended output driver designed to transmit and receive the digital data signals over the bus. The driver and receiver are designed to provide low EMI radiation.

The main function of the TJA1028TK/5V0/20/X is to provide bidirectional communication of serial data between nodes. It can be used in applications where nodes need to communicate using a low data rate, where high reliability and low power consumption is essential. This device is suited to applications where the distance between nodes is up to60 meters and the data rate is up to 1 Mbps.

The device also features Error Detection, Error Identification and Error Diagnostics functions. Error Detection is used to detect errors in the transmitted data by calculating the cyclic redundancy check (CRC) value of the received data. Error Identification and Error Diagnostics features provide additional features like Extended Error Field (EEF) detection, Error Handing and Error Marking that enable the host processor to identify and diagnose the errors that occur on the network. The Error Marking feature allows the failure of the transmit node or host processor to be detected and the corresponding node to be identified.

In summary, the TJA1028TK/5V0/20/X is an integrated circuit, designed to provide low-power, high-speed serial communication capability over CAN and LIN buses, with a data rate of up to 1Mbps. It supports Fault Tolerant and Error Detection/Identification functions and is ideal for applications where reliability and low power consumption are essential. It is also suitable for use in applications where the distance between nodes is up to 20 meters.
