MCP2510
Stand-Alone CAN Controller with SPI™ Interface
Features
Description
• Implements Full CAN V2.0A and V2.0B at 1 Mb/s:
- 0 - 8 byte message length
The Microchip Technology Inc. MCP2510 is a Full Con-
troller Area Network (CAN) protocol controller imple-
menting CAN specification V2.0 A/B. It supports CAN
1.2, CAN 2.0A, CAN 2.0B Passive, and CAN 2.0B
Active versions of the protocol, and is capable of trans-
mitting and receiving standard and extended mes-
sages. It is also capable of both acceptance filtering
and message management. It includes three transmit
buffers and two receive buffers that reduce the amount
of microcontroller (MCU) management required. The
MCU communication is implemented via an industry
standard Serial Peripheral Interface (SPI) with data
rates up to 5 Mb/s.
- Standard and extended data frames
- Programmable bit rate up to 1 Mb/s
- Support for remote frames
- Two receive buffers with prioritized message
storage
- Six full acceptance filters
- Two full acceptance filter masks
- Three transmit buffers with prioritization and
abort features
- Loop-back mode for self test operation
