General 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

  • Vdd : 3.3 / 5.5V
  • Implements CAN 2.0B (ISO11898-1)
  • Three Transmit Buffers with Prioritization and Abort Feature
  • Two Receive Buffers
  • Six Filters and Two Masks, with Optional Filtering on the First Two Data Bytes
  • Supports SPI Modes 0,0 and 1,1
  • Specific SPI Commands to Reduce SPI Overhead
  • Buffer Full, and Request-to-Send Pins Configurable as General Purpose I/O
  • One Interrupt Output Pin

Example

Configuration

  • MCU: P18F87K22
  • Dev.Board: EasyPIC Pro v7
  • Oscillator: 16 Mhz
  • Ext. Modules: MCP25625 click
  • SW: MikroC PRO for PIC
