A complete CAN Node requires a CAN controller, a CAN transceiver and a microcontroller.
The devices are developed as stand-alone CAN (Controller Area Network) controllers. For the connection to the physical layer additional transceiver hardware is required. Two pins of CANTX and CANRX interface to the CAN BUS Transceiver. The devices include a SPI and I2C interfaces to communicate with a microcontroller.
The HT45B3305H/HT45B3315 CAN Module licensed from Bosch. The HT45B3305H/HT45B3315 CAN supports the CAN 2.0 Part A and B protocol specifications and compatible with the ISO11898-1 standards. This CAN Module abbreviated as C_CAN. It is capable of transmitting and receiving standard and extended messages. It also capable of both acceptance filtering and message handler and includes 32 Message Objects which can be concatenated to configurate FIFO buffer with different depth. The SPI interface with data rate of up 10MHz and I2C serial interface are provided for communication with a SPI or I2C based 8-bit MCU.
