TJA1021

LIN 2.0/SAE J2602 transceiver

Rev. 01 — 16 October 2006

Objective data sheet

1. General description

The TJA1021 is the interface between the Local Interconnect Network (LIN) master/slave

protocol controller and the physical bus in a LIN. It is primarily intended for in-vehicle

sub-networks using baud rates from 1 kBd up to 20 kBd and is LIN 2.0/SAE J2602

compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 and improved on

ElectroStatic Discharge (ESD).

The transmit data stream of the protocol controller at the transmit data input (TXD) is

converted by the TJA1021 into a bus signal with optimized slew rate and wave shaping to

minimize ElectroMagnetic Emission (EME). The LIN bus output pin is pulled HIGH via an

internal termination resistor. For a master application an external resistor in series with a

diode should be connected between pin INH or pin V_BATand pin LIN. The receiver detects

the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller.

In sleep mode the power consumption of the TJA1021 is very low, whereas in failure

modes the power consumption is reduced to a minimum.
