2 System Summary
2.1 System Introduction
The EFM32 MCUs are the world’s most energy friendly microcontrollers. With a unique combination of
the powerful 32-bit ARM Cortex-M3, innovative low energy techniques, short wake-up time from energy
saving modes, and a wide selection of peripherals, the EFM32G microcontroller is well suited for any
battery operated application as well as other systems requiring high performance and low-energy con-
sumption. This section gives a short introduction to each of the modules in general terms and also shows
a summary of the configuration for the EFM32G232 devices. For a complete feature set and in-depth
information on the modules, the reader is referred to the EFM32G Reference Manual.
A block diagram of the EFM32G232 is shown in Figure 2.1 (p. 3) .

2.1.1 ARM Cortex-M3 Core
The ARM Cortex-M3 includes a 32-bit RISC processor which can achieve as much as 1.25 Dhrystone
MIPS/MHz. A Memory Protection Unit with support for up to 8 memory segments is included, as well
as a Wake-up Interrupt Controller handling interrupts triggered while the CPU is asleep. The EFM32
implementation of the Cortex-M3 is described in detail in EFM32G Cortex-M3 Reference Manual.
2.1.2 Debug Interface (DBG)
This device includes hardware debug support through a 2-pin serial-wire debug interface. In addition
there is also a 1-wire Serial Wire Viewer pin which can be used to output profiling information, data trace
and software-generated messages.
2.1.3 Memory System Controller (MSC)
The Memory System Controller (MSC) is the program memory unit of the EFM32G microcontroller. The
flash memory is readable and writable from both the Cortex-M3 and DMA. The flash memory is divided
