TJA1021T/20/C,118

The TJA1021T/20/C,118 is an advanced, three-channel transceiver integrated circuit developed by the semiconductor giant NXP. It is designed to be used primarily in CAN bus systems, and its features and design make it suitable for a range of applications.

The TJA1021T/20/C,118 is optimal for automotive applications, due to its ability to function in harsh, ignition environments. With an operating temperature range from -40 to 125 degrees Celsius, it is well-suited for a wide range of applications. It also has integrated safety features, such as built-in error frames for error signalling and CRC cyclic redundancy checks for data verification.

The device supports CAN 2.0B, CAN FD (Flexible Data Rate), and ISO 11898-3. It has a flexible, three-channel design, with two transmit channels for communication, and one receive channel for message reception. The three channels are connected in series, allowing for simultaneous transmission and reception of messages – which is essential in an automotive environment. The device also supports both sleep mode and deep-sleep mode, allowing it to conserve power while also providing high performance.

The device’s architecture is designed to minimize power consumption while providing a robust interfacing solution. It features a low-power standby mode, allowing the supply voltage to drop to 4.2V without affecting performance. It also incorporates an adjustable over-temperature protection (OTP) feature, which will shut off certain functions of the device in the event of an over-temperature event to ensure the device’s longevity.

In terms of performance, the device has very low propagation delays, with a maximum propagation delay of 250ns for uni-directional data frames, and 80ns for switch frames. It has a low error rate, and is compliant with many of the industry standards. The device also supports a wide range of communication and baud rates, with support for CAN 2.0b from 1 Mbps to 2 Mbps, CAN FD from 1Mbps to 8 Mbps, and ISO 45001 from 1Mbps to 4 Mbps.

The device has a single-ended differential driver with an internal current limiter, which limits the output current to 200mA in case of an overload. It also features an electrostatic discharge (ESD) protection circuit, which protects the device from ESD events up to 4000V. It is designed to be compatible with the industry standard 9-pin D-sub connector, and is also compatible with a wide range of connectors and cables, making it a great choice for industrial and automotive applications.

Overall, the TJA1021T/20/C,118 is an advanced transceiver integrated circuit, designed specifically for automotive and industrial applications. Its features and design make it suitable for a wide range of applications, and its compliance with industry standards makes it a great choice for CAN bus systems.
