SPC56xP54x, SPC56xP60x
Introduction
1.5.19
1.5.20
 Programmable transmit-first scheme: lowest ID or lowest buffer number
 Time stamp based on 16-bit free-running timer
 Global network time, synchronized by a specific message
 Maskable interrupts
 Independent of the transmission medium (an external transceiver is assumed)
 High immunity to EMI
 Short latency time due to an arbitration scheme for high-priority messages
 Transmit features
– Supports configuration of multiple mailboxes to form message queues of scalable
depth
– Arbitration scheme according to message ID or message buffer number
– Internal arbitration to guarantee no inner or outer priority inversion
– Transmit abort procedure and notification
 Receive features
– Individual programmable filters for each mailbox
– 8 mailboxes configurable as a six-entry receive FIFO
– 8 programmable acceptance filters for receive FIFO
 Programmable clock source
– System clock
– Direct oscillator clock to avoid PLL jitter
Safety port (FlexCAN)
The SPC56xP54x/SPC56xP60x MCU has a second CAN controller synthesized to run at
high bit rates to be used as a safety port. The CAN module of the safety port provides the
following features:
 Identical to the FlexCAN module
 Bit rate as fast as 7.5 Mb at 60 MHz CPU clock using direct connection between CAN
modules (no physical transceiver required)
 32 Message buffers of 0 to 8 bytes data length
 Can be used as a third independent CAN module
FlexRay
The FlexRay module provides the following features:
 Full implementation of FlexRay Protocol Specification 2.1
 64 configurable message buffers can be handled
 Dual channel or single channel mode of operation, each as fast as 10 Mbit/s data rate
 Message buffers configurable as Tx, Rx or RxFIFO
 Message buffer size configurable
 Message filtering for all message buffers based on FrameID, cycle count and message
ID
 Programmable acceptance filters for RxFIFO message buffers
