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).
