2.2 Memory organization
2.2.1 Introduction
Program memory, data memory, registers and I/O ports are organized within the same linear
4-Gbyte address space.
The bytes are coded in memory in Little Endian format. The lowest numbered byte in a word
is considered the word’s least significant byte and the highest numbered byte the most
significant.
The addressable memory space is divided into 8 main blocks, each of 512 MB.
All the memory areas that are not allocated to on-chip memories and peripherals are
considered “Reserved”). For the detailed mapping of available memory and register areas,
please refer to the Memory map and register boundary addresses chapter and peripheral
chapters.
2.2.2 Memory map and register boundary addresses
The following table gives the memory map and boundary addresses of the peripherals
available in all STM32F05xxx devices.
