Description
The MCP25625 is a complete, cost-effective and small
footprint CAN solution that can be easily added to a
microcontroller with an available SPI interface.
The MCP25625 interfaces directly with microcontrollers
operating at 2.7V to 5.5V; there are no external level
shifters required. In addition, the MCP25625 connects
directly to the physical CAN bus, supporting all
requirements for CAN high-speed transceivers.
The MCP25625 meets the automotive requirements for
high-speed (up to 1 Mb/s), low quiescent current,
Electromagnetic Compatibility (EMC) and Electrostatic
Discharge (ESD).
