LPC178x/177x memory usage and details
General Use
On-chip SRAM
(typically used for
peripheral data)
AHB peripherals

Controller
Cortex-M3 Private
Peripheral Bus
The LPC178x/7x incorporate several distinct memory regions, shown in the following
figures.
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.
