Features and Applications

The MCP2515-E/ST is a Stand-Alone CAN Controller with SPI Interface for implementing CAN specification V2.0B with bit rate up to 1 Mb/s. Available in surface mount TSSOP-20 package.


  • Implements CAN V2.0B at 1 Mb/s:
    • 0 – 8 byte length in the data field
    • Standard and extended data and remote frames
  • Receive buffers, masks and filters:
    • Two receive buffers with prioritized message storage
    • Six 29-bit filters
    • Two 29-bit masks
  • Data byte filtering on the first two data bytes (applies to standard data frames)
  • Three transmit buffers with prioritization and abort features
  • High-speed SPI Interface (10 MHz):
    • SPI modes 0,0 and 1,1
  • One-shot mode ensures message transmission is attempted only one time
  • Clock out pin with programmable prescaler:
    • Can be used as a clock source for other device(s)
  • Start-of-Frame (SOF) signal is available for monitoring the SOF signal:
    • Can be used for time-slot-based protocols and/or bus diagnostics to detect early bus degredation
  • Interrupt output pin with selectable enables
  • Buffer Full output pins configurable as:
    • Interrupt output for each receive buffer
    • General purpose output
  • Request-to-Send (RTS) input pins individually configurable as:
    • Control pins to request transmission for each transmit buffer
    • General purpose inputs
  • Low-power CMOS technology:
    • Operates from 2.7V – 5.5V
    • 5 mA active current (typical)
    • 1 μA standby current (typical) (Sleep mode)
  • Temperature ranges supported:
    • Industrial (I): -40°C to +85°C
    • Extended (E): -40°C to +125°C
