MCP2515
Features:
• 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 pri oritized 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 Progra mm ab le Prescaler:
- Can be used as a clock source for other
device(s)
• Start-of-Frame (SOF) Signal is Available for
Monitori ng the SOF Signal :
- Can be used for time-slot-based protocols
and/or bus diagnostics to detect early bus
degradation
• Interrupt Output Pin with Selectable Enables
• Buffer Full Output Pins Configurable as:
- Interrup t output for each receive buffer
- General purpose output
• Request-to-Send (RTS) Input Pins Individually
Configurable as:
- Control pi ns to request transmis sion for e ac h
transmit buffer
- General purpose inputs
• Low-Power CMOS Technology:
- Operates from 2.7V – 5.5V
- 5 mA active cur rent ( 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
Description
Microchip Technology’s MCP2515 is a stand-alone
Controller Area Network (CAN) controller that
implements the CAN specification, version 2.0B. It is
capable of transmitting and receiving both standard
and extended data and remote frames. The MCP2515
has two acceptance masks and six acceptance filters
that ar e us ed to fi lte r out unwa nte d m ess ag es , the reb y
reducing the host MCU’s overhead. The MCP2515
interfac es wi th microc ontr ollers ( MCUs) via an indu stry
stan dard Serial Peri phe ral Inte rfac e (SPI).
