CAN controller with integrated transceiver, SPI, QFN-28

MCP25625 , CAN Controller with Integrated Transceiver

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).

Features:
- Stand-Alone CAN 2.0B Controller with Integrated CAN Transceiver and SPI
- Up to 1 Mb/s Operation
- Very Low Standby Current (10 µA, typical)
