7.5 CAN
The CAN peripheral is a fully functional Controller Area Network
(CAN) supporting communication baud rates up to 1 Mbps. The
CAN controller implements the CAN2.0A and CAN2.0B
specifications as defined in the Bosch specification and
conforms to the ISO-11898-1 standard. The CAN protocol was
originally designed for automotive applications with a focus on a
high level of fault detection. This ensures high communication

reliability at a low cost. Because of its success in automotive
applications, CAN is used as a standard communication protocol
for motion oriented machine control networks (CANOpen) and
factory automation applications (DeviceNet). The CAN controller
features allow the efficient implementation of higher level
protocols without affecting the performance of the
microcontroller CPU. Full configuration support is provided in
PSoC Creator.
