INTRODUCTION
HIGHLIGHTS
OSCILLATOR CONFIGURATIONS
The capabilities and configurations of the MCP2515 are discussed in this chapter.
This chapter discusses:
• Oscillator Configurations
• Node A Prototyping Area and Header Pinout
• External CAN Bus Connections
The MCP2515 is configured, by default, to use a common oscillator for all three CAN
nodes. While there are three oscillator sockets, only one is populated. The oscillator
sockets are connected together with their outputs. The two jumpers (JP1 and JP2) can
be used to disconnect the outputs and use individual oscillators for the nodes. The
jumpers are shorted by a trace on the bottom of the board by default. These traces can
be cut and jumper pins can be installed to control the oscillator output wiring. See
Figure 5-1 for details on the oscillator configurations.
