LIN Bus Solutions
Scalability and Integration for the Low-Cost Communications Network
Local Interconnect Network (LIN)
LIN/J2602 is a communication standard designed to
address low-cost networking within vehicles. LIN enables
a cost-effective communication network for lower speed
switch, smart sensor and actuator applications within
the vehicle where the bandwidth and versatility of CAN
is not required. LIN can be implemented on any PIC
microcontroller (MCU) with a UART or USART interface.
Microchip also offers a robust physical layer interface,
data link layer implementation, LIN compliant drivers and a
variety of development resources.
Stand-alone LIN Transceivers
The MCP2003/4(A) family offers stand-alone LIN
transceiver options. Both parts meet LIN bus specification
versions 1.3, 2.0 and 2.1 and SAE J2602. The
transceivers' EMC/ESD performance is among the best
in the industry and meets all automotive requirements.
The MCP2003A is available in an industry-standard 8-pin
SOIC package. The MCP2004A offers a TXE/Fault pin
which allows users the ability to disable the transmitter in
addition to providing data related to a fault condition.
LIN Transceivers With Integrated Voltage Regulator
The MCP2021A/2A and MCP2025 integrate a LIN
transceiver and a 3.3V or 5V internal voltage regulator with
a maximum output current of 70 mA. The devices support
the LIN bus specification versions 1.3, 2.0 and 2.1
and SAE J2602 and are designed to meet the stringent
EMC/ESD requirements of the world’s auto makers.
Microchip also offers the MCP2050 LIN Transceiver with
Voltage regulator, windowed watchdog timer and ratio
metric VBAT pin that allows for monitoring battery levels
using a MCU A/D converter.
Integrated Microcontroller with LIN Transceiver and
Voltage Regulator
The PIC16F1829LIN is a small footprint, MCU + VREG +
LIN Transceiver in a single package. Combining the flexible
PIC16F1829 microcontroller with the powerful MCP2021A
LIN transceiver enables a complete solution for LIN nodes
and endpoints, compatible with LIN Specification versions
1.3, 2.0, 2.1, and SAEJ2602.
LIN Software Library
LIN Data Link Layer firmware can be downloaded
free-of-charge from Microchip’s web site. Many third
party companies also offer LIN Data Link Layer firmware,
providing additional design options.
LIN Development Tools
LIN Serial Analyzer Development System (APGDT001)
The LIN analyzer development tool
enables a PC to communicate
with the LIN bus. The PC program
uses a graphical user interface to
enter and display message frames
occurring on the target bus, allowing
for easy debug. It can also be used
as an active node on a bus to send and receive messages,
therefore reducing the application development time.
CAN/LIN PICtail Plus Daughter Board (AC164130-2)
This daughter board can be used with
the Explorer 16 Development board and
various PIMs featuring 16- and 32-bit
MCUs with CAN peripherals, or the PIC18
Explorer board with the PIC18F66K80
PIM to facilitate rapid implementation and evaluation of
CAN and LIN applications.
PICkit 28-pin LIN Demonstration Board (DM164130-3)
The PICkit 28-pin LIN demo board enables
a quick start in developing and debugging
applications with the LIN drivers. The kit
includes a 28-pin socket which supports
various PIC16F devices, a LIN transceiver,
plus a generous prototype area with various
indicator LEDs and buttons to support testing
and debuging of an application.
PICDEM CAN-LIN 3 Demonstration Board (DM163015)
The PICDEM CAN-LIN 3 demo board is
an easy way to discover the power of
Microchip’s CAN and LIN products. The
board demonstrates the main features of
the 64-pin TQFP PIC18F6680 and 80-pin
TQFP PIC18F8680 devices, including those features of the
integrated CAN module. In addition, the board employs a LIN
sub-network using Microchip's 20-pin SSOP PIC18F1320 and
MCP201 LIN Bus.
