TJA1021  
LIN 2.1/SAE J2602 transceiver  
Rev. 05 — 22 October 2009  
Product 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 2.1/SAE J2602  
compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 with an improved  
ElectroStatic Discharge (ESD) specification.  
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 VBAT and 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. In failure modes, the  
power consumption is reduced to a minimum.
