MCP2515
Features
• Implements CAN V2.0B at 1 Mb/s:
- 0 to 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
degradation
• 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
Description
Microchip Technology’s MCP2515 is a stand-alone
Controller Area Network (CAN) controller that imple-
ments 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
are used to filter out unwanted messages, thereby
reducing the host MCU’s overhead. The MCP2515
interfaces with microcontrollers (MCUs) via an industry
standard Serial Peripheral Interface (SPI).
