PICDEM 4 User’s Guide
A.11 LIN
DS51337A-page 16
The PICDEM 4 is designed with an optional LIN circuit (not populated). This circuit
provides the essential circuitry to interface a PICmicro microcontroller to a Local
Interconnect Network (LIN). The circuit includes a MCP201 LIN transceiver, reverse
voltage protection, and over voltage protection.
Jumpers J16, J17, J18, J19, and J20 are provided to set up and connect a PICmicro
microcontroller on PICDEM 4 to the LIN bus. External jumper J16 provides the connec-
tion to the LIN bus. With the MCP201 installed, power to the PICDEM 4 can be supplied
from the LIN bus battery connection via J16; shorting J17 enables bus power to the
circuitry beyond the LIN interface circuit (refer to the MCP201 voltage regulator
specifications for maximum conditions).
Jumpers J18, J19, and J20 provide connections to the microcontroller on the
PICDEM 4. Shorting the appropriate pins (shown on the schematic) can connect either
a PIC16 or PIC18 device to the LIN transceiver. J18 connects the LIN TX pin to either
a PIC16 or PIC18 microcontroller. J19 connects the LIN RX pin to either a PIC16 or
PIC18 microcontroller. J20 provides an additional receive connection for PIC16
devices. For LIN operation, these jumpers must be configured as follows:
• J17 - ON
PIC18
• J18/J19 - Lower two pins ON
• J21 - OFF
PIC16
• J18/J19 - Upper two pins ON
• J20 - ON
• J21 - OFF
