Real Memory Management Unit

The Memory Management and Protection Unit (MMU) handles a virtual address range of 4 Gbytes,

and serves as a hardware firewall to enable secure separation of adjacent application codes and

data. A very efficient context/application switching mechanism allows fast switching between

multiple tasks. Program and data modules are organised as packages. And each package has a

defined memory range of 16 Mbytes with dedicated access rights for memories and peripherals.

The flexible MMU concept also shortens development cycles for additional applications. It

furthermore enables the secure downloading of applications in the field.

Power Consumption

SLE 88CFX4002P includes an intelligent power management module that covers the voltage

classes A, B and C of the 3rd generation specification for mobile communication TS102 221.
