5 Memory and Bus System
5.1 Introduction
5.2 Functional Description
2010-09-06 - d0001_Rev1.00
The EFM32G contains 4 main memory segments which can be accessed by the Cortex-M3 or the DMA
controller:
• Flash
• RAM
• External Bus Interface (EBI)
• Peripherals
The memory segments are mapped together with the internal segments of the Cortex-M3 into the system
memory map shown by Figure 5.1 (p. 14)

What?
A low latency memory system including low
energy Flash and RAM with data retention
which makes the energy modes attractive.
Why?
RAM retention reduces the need for storing
data in Flash and enables frequent use of the
ultra low energy modes EM2 and EM3 with
as little as 0.6 µA µA current consumption.
How?
Low energy and non-volatile Flash memory
stores program and application data
in all energy modes and can easily be
reprogrammed in system. Low leakage RAM
with data retention in EM0 to EM3 removes
the data restore time penalty, and the DMA
ensures fast autonomous transfers with
predictable response time.
