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 EFM32TG 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 and
shows a summary of the configuration for the EFM32TG822 devices. For a complete feature set and in-
depth information on the modules, the reader is referred to the EFM32TG Reference Manual.
A block diagram of the EFM32TG822 is shown in Figure 2.1 (p. 3) .

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 EFM32 Cortex-M3 Reference Manual.
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.
The Memory System Controller (MSC) is the program memory unit of the EFM32TG microcontroller.
The flash memory is readable and writable from both the Cortex-M3 and DMA. The flash memory is
