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 88CFX4000P 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.
