LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
The MPU allows separating processing tasks by disallowing access to each other's data,
disabling access to memory regions, allowing memory regions to be defined as read-only
and detecting unexpected memory accesses that could potentially break the system.
The MPU separates the memory into distinct regions and implements protection by
preventing disallowed accesses. The MPU supports up to 8 regions each of which can be
divided into 8 subregions. Accesses to memory locations that are not defined in the MPU
regions, or not permitted by the region setting, will cause the Memory Management Fault
exception to take place.
7.6 Memory map
The LPC17xx incorporates several distinct memory regions, shown in the following
figures. Figure 4 shows the overall map of the entire address space from the user
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.
