•

Conforms with ISO 11898-1:2015

•

Full CAN FD support (up to 64 data bytes)

•

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 filter elements

•

Internal Loopback mode for self-test

•

Maskable 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

•
