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.
7.5.1 CAN Features
Document Number: 001-11729 Rev. *R
CAN2.0A/B protocol implementation – ISO 11898 compliant
Listen Only mode
SW readable error counter and indicator
Sleep mode: Wake the device from sleep with activity on the
