SPRS584J –APRIL 2009–REVISED OCTOBER 2013

4.5 Local Interconnect Network (LIN)

The device contains one LIN controller. The LIN standard is based on the SCI (UART) serial data link

format. The LIN module can be configured to work as a SCI as well.

The LIN module has the following features:

• Compatible to LIN 1.3 or 2.0 protocols

• Two external pins: LINRX and LINTX

• Multi-buffered receive and transmit units

• Identification masks for message filtering

• Automatic master header generation

– Programmable sync break field

– Sync field

– Identifier field

• Slave automatic synchronization

– Sync break detection

– Optional baudrate update

– Synchronization validation

• 2

programmable transmission rates with 7 fractional bits

• Wakeup on LINRX dominant level from transceiver

• Automatic wakeup support

– Wakeup signal generation

– Expiration times on wakeup signals

• Automatic bus idle detection

• Error detection

– Bit error

– Bus error

– No-response error

– Checksum error

– Sync field error

– Parity error

• 2 Interrupt lines with priority encoding for:

– Receive

– Transmit

– ID, error and status

NOTE

The 2803x devices have passed LIN 2.0 conformance tests (master and slave). Contact TI

for details.
