Product details
Overview
TJA1080ATS/2/T,118 from NXP Semiconductors is a FlexRay transceiver compliant with FlexRay V2.1 Rev. A and supporting V3.0.1 features, operating at data rates up to 10 Mbit/s with 60 ns minimum bit time. It functions as either a node or active star transceiver in automotive time-triggered networks, providing differential transmit/receive capability, bus error detection, and integrated voltage/temperature monitoring for chassis control units and domain controllers.
For engineers reviewing the TJA1080ATS/2/T,118 datasheet, TJA1080ATS/2/T,118 pinout, TJA1080ATS/2/T,118 application, or TJA1080ATS/2/T,118 equivalent, key selection criteria include FlexRay V2.1/V3.0.1 compliance, 10 Mbit/s operation, SSOP20 package compatibility, dual-mode (node/star) configuration, and diagnostic features including ERRN signaling and wake-source recognition.
Technical Context
The TJA1080ATS/2/T,118 implements a dual-configuration architecture supporting both linear passive bus topologies and active star topologies via TRXD0/TRXD1 pin configuration during power-on. Its internal state machine autonomously manages mode transitions in star configuration while supporting EN/STBN-controlled modes in node configuration.
It integrates dedicated hardware-level diagnostics: overtemperature detection, bus short-circuit sensing, VBAT/VCC/VIO undervoltage flags, and wake-source identification. The transceiver provides auto I/O level adaptation to host controller supply voltage (VIO = 2.2 V to 5.25 V), supports 14 V and 42 V automotive systems, and delivers fail-silent behavior under undervoltage conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FlexRay transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1080TS/2/T | Base TJA1080 variant; lacks improved power-on reset, 60 ns bit time support, and enhanced EME performance. | Suitable for legacy FlexRay systems not requiring V3.0.1 features or stricter EMI limits. | Select only if cost sensitivity outweighs need for V3.0.1 compliance and improved EMC. |
| MC33664AE | Freescale/NXP legacy part; supports FlexRay V2.1 only; no TRXD0/TRXD1 star interface; different pinout and diagnostic signaling. | Used in earlier-generation FlexRay nodes where star topology is not implemented. | Not pin-compatible; requires PCB redesign and firmware adaptation for ERRN/WAKE handling. |
Compared with TJA1080TS/2/T and MC33664AE, the TJA1080ATS/2/T,118 delivers verified V3.0.1 feature support, dual topology flexibility, and lower EME - making it the preferred choice for new designs targeting ASIL-B/C system integration.

FAQ
What is the primary function of the TJA1080ATS/2/T,118 in a FlexRay network?
The TJA1080ATS/2/T,118 serves as a physical layer transceiver that bridges the FlexRay protocol controller to the differential bus (BP/BM), supporting both node and active star configurations. It handles signal conditioning, fault detection, and mode management - ensuring reliable, high-speed (up to 10 Mbit/s) communication in automotive safety-critical systems. The TJA1080ATS/2/T,118 implements V2.1 Rev. A compliance with V3.0.1 enhancements including 60 ns minimum bit time and improved bus error detection.
How does the TJA1080ATS/2/T,118 support both node and star topologies?
The TJA1080ATS/2/T,118 detects topology at power-on: grounding TRXD0 and TRXD1 configures it as a node transceiver, while connecting either TRXD pin to VBUF selects active star mode. In star mode, it autonomously manages Star-idle, Star-transmit, and Star-receive states using internal logic - eliminating need for external mode control. The TJA1080ATS/2/T,118 retains full diagnostic visibility (ERRN, WAKE, RXEN) regardless of topology.
What are the key power supply requirements for the TJA1080ATS/2/T,118?
The TJA1080ATS/2/T,118 requires four independent supplies: VBAT (6.5–60 V), VCC/VBUF (4.75–5.25 V), and VIO (2.2–5.25 V). This separation enables flexible power sequencing and compatibility with 12 V and 42 V automotive systems. Undervoltage detection on all rails triggers fail-silent behavior, and VIO adaptation allows direct interfacing with 3.3 V or 5 V microcontrollers. The TJA1080ATS/2/T,118 draws <100 µA in Star-sleep mode for ultra-low-power park functionality.
Does the TJA1080ATS/2/T,118 provide diagnostic capabilities beyond basic error signaling?
Yes - the TJA1080ATS/2/T,118 offers comprehensive hardware diagnostics: overtemperature detection, bus short-circuit sensing, VBAT/VCC/VIO undervoltage flags, wake-source identification (local vs. remote), and pin clamping detection on TXEN/BGE. The ERRN pin provides serializable diagnostic status, and internal flags (PWON, Wake, UVxx) are accessible via microcontroller reads. These features are fully documented in the TJA1080ATS/2/T,118 datasheet Sections 6.2–6.5 and Table 4–7.
Is the TJA1080ATS/2/T,118 pin-compatible with earlier NXP FlexRay transceivers?
Yes - the TJA1080ATS/2/T,118 is fully pin-compatible with the TJA1080 (Ref. 5), sharing identical SSOP20 pinout and footprint. It retains the same excellent ESD protection and adds improvements including enhanced power-on reset, improved EME, 60 ns bit time support, and upgraded bus error detection. Migration to the TJA1080ATS/2/T,118 requires no PCB changes but enables V3.0.1 feature adoption in existing designs.
