The device integrates two CAN-FD (CAN with
Flexible Data-rate) interfaces which allows high throughput and increased payload
per data frame. This enables support of a typical use case where one CAN-FD
interface is used as an ECU network interface while the other as a local network
interface, providing communication with the neighboring sensors.
The CAN-FD has the following features:
- Conforms with CAN Protocol 2.0 A, B and ISO 11898-1
- Full CAN FD support (up to 64 data bytes per frame)
- AUTOSAR and SAE J1939 support
- Up to 32 dedicated Transmit Buffers
- Configurable Transmit FIFO, up to 32 elements
- Configurable Transmit Queue, up to 32 elements
- Configurable Transmit Event FIFO, up to 32 elements
- Up to 64 dedicated Receive Buffers
- Two configurable Receive FIFOs, up to 64 elements each
- Up to 128 11-bit filter elements
- Internal Loopback mode for self-test
- Mask-able interrupts, two interrupt lines
- Two clock domains (CAN clock / Host clock)
- Parity / ECC support - Message RAM single error correction and double error detection (SECDED) mechanism
- Full Message Memory capacity (4352 words).
