Formal Name

Definition

WAKE1

Wake Input

This pin is a high-voltage input used to wake-up the LIN1 from Sleep mode.

TXD1

Data Input

This pin is the transmitter input of the LIN1 interface which controls the state of the bus

output.

LIN1

LIN Bus

This bidirectional pin represents the LIN1 single-wire bus transmitter and receiver.

LIN2

LIN Bus

This bidirectional pin represents the LIN2 single-wire bus transmitter and receiver.

INH2

Inhibit Output

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.

RXD2

Data Output

This pin is the receiver output of the LIN2 interface, which reports the state of the bus

voltage to the MCU interface.

EN2

Enable Control

This pin controls the operation mode of the LIN2 interface.

WAKE2

Wake Input

This pin is a high-voltage input used to wake-up the LIN2 device from Sleep mode.

GND

Ground

This pin is the device ground pin.

TXD2

Data Input

This pin is the transmitter input of the LIN2 interface, which controls the state of the bus

output.

VSUP

Power Supply

This pin is device battery level power supply.
