CS8972 EVB - Product Image
Description
The CS8972 EVB is a stand-alone Controller Area Network (CAN) protocol controller with the embedded CAN transceiver. The CAN transceiver meets or exceeds ISO 11898 standards. As CAN transceivers, these devices provide differential transmit and receive capability as signaling rates up to 1 Mb/s for a CAN controller. It is capable of transmitting and receiving standard and extended message frames. It includes eight independent auto-dispatch and 1024-byte transmit buffers, FIFO receives filtering with 12 ID acceptance and message management. The MCU communication is implemented via an industry standard Serial Peripheral Interface (SPI) and an I2C bus.
Key Features
- The CS8972 is a stand-alone CAN protocol controller with the embedded CAN transceiver.
- It supports standard CAN 2.0B, and the maximal bit rate is 1 Mb/s.
- CS8972 provides two popular serial interfaces for external MCU communication, Serial Peripheral Interface (SPI) and an I 2C bus.
- SPI and I2C are both slave controllers in CS8972. They receive and respond through the selected serial interface to MCU commands.
- In CS8972, MCU only implements a slave SPI controller to receive and respond to the commands.
