MCP2515

Stand-Alone CAN Controller with SPI Interface

Features:

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 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).

• 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)
