LIN 2.1 / SAEJ2602-2 Dual LIN
Physical Layer
The local interconnect network (LIN) is a serial communication
protocol designed to support automotive networks in conjunction with
controller area network (CAN). As the lowest level of a hierarchical
network, LIN enables cost-effective communication with sensors and
actuators when all the features of CAN are not required.
The 33663 product line integrates two physical layer LIN bus
dedicated to automotive LIN sub-bus applications. The MC33663LEF
and MC33663SEF devices offer normal baud rate (20 kbps) and the
MC33663JEF slow baud rate (10 kbps). Both devices integrate fast
baud rate (above 100 kbps) for test and programming modes. They
present excellent electromagnetic compatibility (EMC) and radiated
emission performance, electrostatic discharge (ESD) robustness and
safe behavior, in the event of LIN bus short-to-ground or LIN bus
leakage during low-power mode.

Definition
This pin is a high-voltage input used to wake-up the LIN1 from Sleep mode.
This pin is the transmitter input of the LIN1 interface which controls the state of the bus
output.
This bidirectional pin represents the LIN1 single-wire bus transmitter and receiver.
This bidirectional pin represents the LIN2 single-wire bus transmitter and receiver.
This pin can have two main functions: controlling an external switchable voltage
regulator having an inhibit input, or driving an external bus resistor connected to LIN2 in
the master node application.
This pin is the receiver output of the LIN2 interface, which reports the state of the bus
voltage to the MCU interface.
This pin controls the operation mode of the LIN2 interface.
This pin is a high-voltage input used to wake-up the LIN2 device from Sleep mode.
This pin is the device ground pin.
This pin is the transmitter input of the LIN2 interface, which controls the state of the bus
output.
This pin is device battery level power supply.
This pin can have two main functions: controlling an external switchable voltage
regulator having an inhibit input, or driving an external bus resistor connected to LIN1 in

Notes
1. Class A: All functions of a device/system perform as designed during and after exposure to disturbance.
2. Class D: At least one function of the Transceiver stops working properly during the test and will return into proper operation automatically
when the exposure to the disturbance has ended. No physical damage of the IC occurs.
