DESCRIPTION
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 messages.
It is also capable of both acceptance filtering and mes-
sage management. It includes three transmit buffers and
two receive buffers that reduce the amount of microcon-
troller (MCU) management required. The MCU commu-
nication is implemented via an industry standard Serial
Peripheral Interface (SPI) with data rates up to 5Mb/s.
