Peripheral CAN[edit | edit source]
The MCAN modules in the DADA SOM conform to the CAN Protocol 2.0 A, B and ISO 11898-1. The MCAN module supports both classic CAN and CAN FD (CAN with Flexible Data-Rate) specifications. CAN FD feature allows high throughput and increased payload per data frame.
Description[edit | edit source]
Each MCAN module has the following features:
- Full CAN FD support (up to 64 data bytes)
- SAE J1939 support
- AUTOSAR support
- Up to 32 dedicated Transmit Buffers: configurable Transmit FIFO, Transmit Queue and Transmit Event FIFO up to 32 elements (each one)
- Up to 64 dedicated Receive Buffers: two configurable Receive FIFOs, up to 64 elements each
- Up to 128 filter elements
- Internal Loopback mode for self-test
- Two clock domains (CAN clock/Host clock)
- Parity/ECC support - Message RAM single error correction and double error detection (SECDED) mechanism
- Timestamp Counter
