Both the CAN and LIN protocols were originally created 
for the automotive market. CAN was designed as a high 
reliability and speed protocol (up to 1 Mbit/s) for the harsh 
environment of the car electrical bus. LIN was later added 
as a simple low cost alternative for the control of non-critical 
modules on a vehicle. Both find occasional applications in 
lighting.

Many of the PIC18F, PIC24H, PIC32 microcontrollers and 
dsPIC DSCs include a complete CAN serial interface. The 
MCP25XX series of peripheral interfaces includes several 
CAN transceiver and CAN I/O expander devices.

All PIC microcontroller devices offering an EUSART module 
(PIC18F devices and most recent PIC16F devices) offer 
direct support for LIN bus connectivity with auto-baud rate 
detection and specific low power features.

The Automotive Ambient Interior Lighting 
Module Reference Design demonstrates 
microcontroller-based control of RGB LED 
devices. This module can be controlled 
remotely by a master body controller via 

a LIN bus. These modules are offered in a very compact 
form-factor board and are comprised of a PIC12F615 MCU, 
an MCP2021 LIN transceiver/voltage regulator, and RGB 
LED. LIN commands are interpreted by the module to control 
color mixing (16,383 colors) and intensity (1023 levels). 
The kit ships with 4 modules to assign as lighting zones in 
a LIN or J2602 network. These modules can also be used in 
conjunction with the APGDT001 LIN Serial Analyzer to quickly 
create a working LIN network straight out of the box.

With the demise of the serial port, any application that 
requires a connection with a personal computer has now 
to be routed to the USB port. Some innovative lighting 
applications occasionally require such a connection to be 
established. Several models of PIC18F microcontrollers 
incorporate a complete USB interface. Several interface 
examples are offered to the designer to simplify the 
transition from serial port to USB and to integrate the 
application with existing Microsoft Windows® drivers.

Ethernet connectivity is becoming ubiquitous and most new 
office and industrial building are being wired for Ethernet. As 
lower cost solutions are becoming available it is increasingly 
tempting to use Ethernet for even the simplest control and 
diagnostic applications.

Microchip addresses the growing demand for a small 
and low-cost embedded Ethernet solution by offering the 
following:

■

 

PIC32MX6XX and PIC32MX7XX families with integrated 
10/100 Ethernet MAC, dedicated DMA interface supports 
packet scatter/gather for outstanding low CPU-overhead 
performance at full 100 Megabit/seconds. Industry 
standard RMII/MII interface, pre-programmed unique 
MAC address. This family is fully compatible with 
10/100/1000 Base-T networks

■

 

10/100 Base-T ENC624J600 standalone Ethernet 
controllers which are IEEE 802.3 compliant, integrated 
with hardware cryptographic security engines and factory 
preprogrammed unique MAC address. This family is fully 
compatible with 10/100/1000 Base-T networks

■

 

10 Base-T ENC28J60 standalone Ethernet controller and 
the PIC18F97J60 family, which are IEEE 802.3 compliant 
and fully compatible with 10/100/1000 Base-T networks

■

 

Free licensed and robust TCP/IP stack, which is optimized 
for the PIC18, PIC24 and PIC32 microcontroller and dsPIC 
digital signal controller families
