TJA1080ATS/2/T,112

Specialized Overview

The TJA1080ATS/2/T,112 is a FlexRay transceiver compliant with specification V2.1 Rev. A and incorporating V3.0.1 features. It supports data transfer rates up to 10 Mbit/s and accommodates 14 V and 42 V powered systems. The device operates within a temperature range of -40 °C to +150 °C and utilizes an SSOP20 package (SOT339-1). Supply voltages include VBAT (6.5 V to 60 V), VCC (4.75 V to 5.25 V), VBUF (4.75 V to 5.25 V), and VIO (2.2 V to 5.25 V). It provides 8 kV HBM ESD protection on bus pins.

Specialized Feature Summary

• Configurable as active star or node transceiver for FlexRay networks
• Supports low power management with local and remote wake-up capabilities
• Includes diagnosis functions such as overtemperature and short-circuit detection
• Features fail-silent behavior during undervoltage conditions

Specialized Applications

• Time-triggered communication systems in automotive environments

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm that the component meets the required AEC-Q100 qualification standards for your target application environment before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing FlexRay interfaces requiring support for both linear passive and active star topologies. Ensure the host controller supply voltage falls within the 2.2 V to 5.25 V range for proper I/O level adaptation. Verify compatibility with the system's battery voltage architecture, supporting both 14 V and 42 V configurations.

Specialized Part Context

This part belongs to the NXP TJA1080A family of FlexRay transceivers. It serves as an advanced interface between the protocol controller and the physical bus. The device represents an evolution from the standard TJA1080, offering improved power-on reset concepts and enhanced electromagnetic emission performance while maintaining pin compatibility.

Specialized Replacement Considerations

The TJA1080ATS/2/T,112 is functionally compatible with the standard TJA1080ATS due to identical pinouts. Designers migrating from the original TJA1080 should review the datasheet section detailing differences in bit time support and error detection functionality.
