The MCAN module supports up to 5 Mbit/s data rate and is compliant to ISO 11898-1:2015. The MCAN module implements the following features: • 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 • Local power-down and wakeup support • Timestamp Counter NOTE For more information, see the Serial Communication Interfaces / DCAN and MCAN sections of the Device TRM. Table 5-59, Table 5-60 and Figure 5-45 present Timing and Switching characteristics for DCAN and MCAN Interface. Table 5-59. Timing Requirements for DCAN Receive(1) NO. PARAMETER DESCRIPTION MIN NOM MAX UNIT f(baud) Maximum programmable baud rate 1 Mbps 1 tw(DCANRX) Pulse duration, receive data bit (DCANx_RX) H - 15 H + 15 ns |
