PINOUT DIFFERENCES
MCP2551 PDIP, SOIC
MCP2561 PDIP, SOIC
INTRODUCTION
The MCP2561 is Microchip’s second generation CAN transceiver. Although major improvements have been made, resulting in increased EMC performance and much lower current consumption, the differences in using the MCP2561 versus the MCP2551 are minor.
Figure 1 shows the differences in pinout.
The MCP2561 can be used as a drop-in replacement for the MCP2551 if the differences listed in Table 1 are considered.
