TJA1080TS,118

Specialized Overview

The TJA1080TS,118 is a FlexRay transceiver compliant with the FlexRay electrical physical layer specification V2.1 Rev. A. It provides an advanced interface between the protocol controller and the physical bus in a FlexRay network, supporting data transfer rates up to 10 Mbit/s. The device can be configured as an active star transceiver or a node transceiver. It operates within a battery supply voltage (VBAT) range of 6.5 V to 60 V and a VCC/VBUF supply voltage range of 4.75 V to 5.25 V. The component features low power management with very low current consumption in Sleep and Standby modes. It includes comprehensive diagnosis capabilities such as overtemperature detection, short-circuit protection, and undervoltage detection. The transceiver offers high ESD protection against 8 kV HBM pulses and complies with ISO 7637 class C for automotive transients.

Specialized Selection Notes

Select this component when designing FlexRay networks requiring support for both active star and node configurations. Ensure the host microcontroller supports the required mode control signals and diagnostic interfaces. Verify that the application environment stays within the specified operating temperature range of -40 °C to +150 °C virtual junction temperature. Confirm that the power supply rails meet the minimum operating voltages for VBAT, VCC, and VIO to ensure proper initialization and functionality.

Specialized Part Context

The TJA1080 is part of NXP Semiconductors' specialized interface IC portfolio designed for automotive communication protocols.
