FlexRAM/

SRAM

1: On this device, NXP’s system MPU implements the safety mechanisms to prevent masters from

accessing restricted memory regions. This system MPU provides memory protection at the

level of the Crossbar Switch. Each Crossbar master (Core, DMA, Ethernet) can be assigned

different access rights to each protected memory region. The Arm M4 core version in this family

does not integrate the Arm Core MPU, which would concurrently monitor only core-initiated memory

accesses. In this document, the term MPU refers to NXP’s system MPU.

2: For the device-specific sizes, see the "On-chip SRAM sizes" table in the "Memories and Memory Interfaces"

chapter of the S32K1xx Series Reference Manual.

3: CSEc (Security) or EEPROM writes/erase will trigger error flags in HSRUN mode (112 MHz) because this

use case is not allowed to execute simultaneously. The device need to switch to RUN mode (80 MHz) to

execute CSEc (Security) or EEPROM writes/erase.
