C2000 Microcontroller Workshop - Architecture Overview 1 - 9
Memory
The memory space on the F28x is divided into program memory and data memory. There are
several different types of memory available that can be used as both program memory and data
memory. They include the flash memory, single access RAM (SARAM), OTP, and Boot ROM
which is factory programmed with boot software routines and standard tables used in math related
algorithms.
Memory Map
The F28x CPU contains no memory, but can access memory on chip. The F28x uses 32-bit data
addresses and 22-bit program addresses. This allows for a total address reach of 4G words (1
word = 16-bits) in data memory and 4M words in program memory. Memory blocks on all F28x
designs are uniformly mapped to both program and data space.
This memory map shows the different blocks of memory available to the program and data space.

The F28069 utilizes a contiguous memory map, also known as a von-Neumann architecture. This
type of memory map lends itself well to higher-level languages. This can be seen by the labels
located at the top of the memory map where the memory blocks extend between both the data
space and program space.
At the top of the map, we have two blocks of RAM called M0 and M1. Then we see PF0 through
PF3, which are the peripheral frames. This is the area where you will find the peripheral
registers. Also in this space, you will find the PIE block. Memory blocks L0 through L8 are
grouped together. L0 through L3 are accessible by the CPU and CLA. L5 through L8 are
accessible by the DMA.
