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 transmitting
and receiving standard and extended messages. 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 Periph-
eral Interface (SPI) with data rates up to 5Mb/s.
