First certified LIN 2.1 transceiver is unveiled by NXP

NXP Semiconductors has released the industry's first transceiver to be certified according to the recently established LIN 2.1 specification.

A safe and comfortable automotive driving experience requires reliable communication between electronic control units within the car, making certification of core electronics components vital. As the market's first certified LIN 2.1 compliant transceiver, the TJA1021 was tested against new criteria released in October 2008. LIN 2.1 represents the next evolution of the Local Interconnect Network standard and incorporates new criteria including enhanced transport layer criteria, addition of diagnostics and backwards compatibility. The NXP TJA1021 brings energy efficiency and component cost reduction to the company's LIN transceiver portfolio. The TJA1021 sets a new standard in ESD performance with 8 kV HBM and 6 kV, in accordance with the IEC 61000-4-2 standard. The level of performance enables manufacturers to build electronic control units without incorporating external ESD protection, thus reducing overall system costs.

The NXP TJA1021 transceiver features:

ESD performance enabling reduced component cost.

Low sleep current, low leakage current and low operation voltage, that contributes into reduced power consumption and less CO2 emission in the car.

Ultra low sleep power consumption that will significantly reduce the battery drain when vehicle is parked.

Low operation voltage down to 5.5V that will make the device a candidate in engine start related applications such as start stop that can help to further reduce CO2 on the system level.

Backwards PIN compatibility with TJA1020.


The TJA1021 is in full production.
