Reliable, Low-Cost Networking

Low-cost Local Interconnect Network (LIN) systems are used throughout the automobile in comfort, powertrain, sensor, and actuator applications.

The modular Microchip LIN family ranges from simple transceiver ICs to complex system basis chips with LIN transceiver, voltage regulator and watchdog. At higher integration levels, the Microchip System-in-Package (SIP) solutions feature an Atmel AVR® , an ARM Cortex M0+ microcontroller or PIC microcontroller, LIN transceiver, voltage regulator and watchdog in a single package.

Key Features

  • High level of integration – Depending on the individual integration level, we embed a large number of functions into our LIN devices, including LIN transceiver, voltage regulator, watchdog and microcontroller, so you don’t have to add these capabilities later.
  • Broad portfolio – Microchip gives you the broadest in-vehicle networking (IVN) product portfolio on the market with modular families at all integration levels to meet diverse application requirements.
  • Proven reputation – Approval of all major car manufacturers is available.
  • Advanced application support – A broad range of development tools give you a quick start on developing, prototyping and testing new designs.
  • Family footprint – The ATA6632/33/34 series of devices also provide a family footprint so designers can upgrade their designs with various devices within these series.

One of Microchip Technology’s key design partners, IHR GmbH, has developed LIN-compliant drivers for Microchip’s PIC16F, PIC18F and PIC24F families of microcontrollers.

IHR is one of the leading manufacturers of diagnosis and emulation tools, as well as gateways for the automotive industry. IHR GmbH is also an associated member of the LIN consortium and has been performing LIN conformance tests for LIN 1.3, LIN 2.0 and LIN 2.1 test specifications.

To further aid the user in configuring the driver for their end application, IHR has developed a LIN Configuration Tool. This tool helps automate the process of generating LIN-compliant code which contains bus configuration information, node information and signal data using the LIN Description File (LDF).
