MCP25625 CAN Controller with Integrated Transceiver General Features CAN Transceiver Features Stand-Alone CAN 2.0B Controller with Integrated V : 4.5V to 5.5V DDA CAN Transceiver and Serial Peripheral Implements ISO-11898-2 and ISO-11898-5 Interface (SPI) Standard Physical Layer Requirements Up to 1 Mb/s Operation CAN Bus Pins are Disconnected when Device is Very Low Standby Current (10 A, typical) Unpowered: Up to 10 MHz SPI Clock Speed - An unpowered node or brown-out event will not load the CAN bus Interfaces Directly with Microcontrollers with 2.7V to 5.5V I/Os Detection of Ground Fault: Available in SSOP-28L and 6x6 QFN-28L - Permanent Dominant detection on T XD Temperature Ranges: - Permanent Dominant detection on bus - Extended (E): -40C to +125C Power-on Reset and Voltage Brown-Out Protection on V Pin DDA Protection Against Damage Due to Short-Circuit CAN Controller Features Conditions (Positive or Negative Battery Voltage) V : 2.7 to 5.5V DD Protection Against High-Voltage Transients in Implements CAN 2.0B (ISO11898-1) Automotive Environments Three Transmit Buffers with Prioritization and Automatic Thermal Shutdown Protection Abort Features Suitable for 12V and 24V Systems Two Receive Buffers Meets or Exceeds Stringent Automotive Design Six Filters and Two Masks with Optional Filtering Requirements, Including Hardware Require- on the First Two Data Bytes ments for LIN, CAN and FlexRay Interfaces in Supports SPI Modes 0,0 and 1,1 Automotive Applications, Version 1.3, May 2012 Specific SPI Commands to Reduce SPI Overhead High Noise Immunity Due to Differential Bus Buffer Full and Request-to-Send Pins are Implementation Configurable as General Purpose I/Os High-ESD Protection on CANH and CANL, Meets One Interrupt Output Pin IEC61000-4-2 up to 8 kV 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 1Mb/s), low quiescent current, Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD). 2014-2019 Microchip Technology Inc.
