TJA1021T/10/CM,118

Drivers, Receivers, Transceivers Overview

The TJA1021T/10/CM,118 is a LIN transceiver designed for in-vehicle sub-networks. It interfaces between the LIN protocol controller and the physical bus, supporting baud rates up to 10.4 kBd per SAE J2602 standards. The device complies with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12 V), and SAE J2602 specifications. It operates within a battery supply voltage range of 5.5 V to 27 V and supports a virtual junction temperature range from -40 °C to +150 °C. The component is housed in an SOIC-8 package.

Drivers, Receivers, Transceivers Feature Summary

• Optimized low-slope output waveform design minimizes electromagnetic emission while maintaining high immunity.
• Integrated responder termination resistor simplifies hardware implementation for LIN slave nodes.
• Supports local wake-up via WAKE_N pin and remote wake-up via LIN bus dominant state detection.
• Includes TXD dominant time-out function to prevent permanent bus blocking during hardware failures.

Drivers, Receivers, Transceivers Applications

• In-vehicle LIN sub-networks requiring compliance with SAE J2602 standard
• LIN responder or slave node implementations in automotive body electronics
• Systems requiring low power consumption with local and remote wake-up capabilities

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix /10 corresponds to the low-slope variant optimized for 10.4 kBd operation. Confirm the CM,118 suffix indicates the correct SOIC-8 tape and reel packaging configuration required for automated assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this variant over the /20 version when system requirements strictly adhere to the SAE J2602 maximum speed limit of 10.4 kBd. The reduced slew rate provides superior electromagnetic compatibility performance compared to the normal slope variants.

Drivers, Receivers, Transceivers Part Context

This component belongs to the NXP TJA1021 family of LIN transceivers. It serves as the physical layer interface for Local Interconnect Network applications. The device is pin-to-pin compatible with the TJA1020 and MC33662(B) series, facilitating direct upgrades in existing designs.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1021AT(K)/10 is a confirmed functional substitute within the same product family offering identical low-slope characteristics and pinout compatibility.
