NXP Semiconductors MPC5777M Safety Manual

Safety Manual for MPC5777M, Rev. 1.1
Functional safety requirements for application software
NXP Semiconductors48
To allow a safety application to make redundant use of all I/O peripherals, the peripherals have two
instances and each instance is connected to a different peripheral bridge (PBRIDGE). The arrangement of
the I/O peripherals onto two PBRIDGEs allows redundant use of peripherals while limiting CCFs.
The MPC5777M architecture allows making redundant use of the communication peripherals like
LINFlexD, DSPI and PSI5. Figure 2 shows the distribution of the MPC5777M peripherals.
Figure 2. MPC5777M peripheral allocation
As a usage example, if an application needs to use LIN communications protocol, two different LINFlexD
modules may be used; one connected to the PBRIDGEA and one the PBRIDGEB.
