2 System Summary
...the world's most energy friendly microcontrollers
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 EFM32GG microcontroller is well suited for
any battery operated application as well as other systems requiring high performance and low-energy
consumption. This section gives a short introduction to each of the modules in general terms and also
shows a summary of the configuration for the EFM32GG842 devices. For a complete feature set and
in-depth information on the modules, the reader is referred to the EFM32GG Reference Manual.
A block diagram of the EFM32GG842 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 EFM32 Cortex-M3 Reference Manual.
2.1.2 Debug Interface (DBG)
This device includes hardware debug support through a 2-pin serial-wire debug interface and an Embed-
ded Trace Module (ETM) for data/instruction tracing. 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 EFM32GG microcontroller.
The flash memory is readable and writable from both the Cortex-M3 and DMA. The flash memory is

...the world's most energy friendly microcontrollers
2.1.19 Analog Comparator (ACMP)
The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indi-
cating which input voltage is higher. Inputs can either be one of the selectable internal references or from
external pins. Response time and thereby also the current consumption can be configured by altering
the current supply to the comparator.
2.1.20 Voltage Comparator (VCMP)
The Voltage Supply Comparator is used to monitor the supply voltage from software. An interrupt can
be generated when the supply falls below or rises above a programmable threshold. Response time and
thereby also the current consumption can be configured by altering the current supply to the comparator.
2.1.21 Analog to Digital Converter (ADC)
The ADC is a Successive Approximation Register (SAR) architecture, with a resolution of up to 12 bits
at up to one million samples per second. The integrated input mux can select inputs from 8 external
pins and 6 internal signals.
2.1.22 Digital to Analog Converter (DAC)
The Digital to Analog Converter (DAC) can convert a digital value to an analog output voltage. The DAC
is fully differential rail-to-rail, with 12-bit resolution. It has two single ended output buffers which can be
combined into one differential output. The DAC may be used for a number of different applications such
as sensor interfaces or sound output.
2.1.23 Operational Amplifier (OPAMP)
The EFM32GG842 features 3 Operational Amplifiers. The Operational Amplifier is a versatile general
purpose amplifier with rail-to-rail differential input and rail-to-rail single ended output. The input can be set
to pin, DAC or OPAMP, whereas the output can be pin, OPAMP or ADC. The current is programmable
and the OPAMP has various internal configurations such as unity gain, programmable gain using internal
resistors etc.
2.1.24 Low Energy Sensor Interface (LESENSE)
The Low Energy Sensor Interface (LESENSETM), is a highly configurable sensor interface with support
for up to 16 individually configurable sensors. By controlling the analog comparators and DAC, LESENSE
is capable of supporting a wide range of sensors and measurement schemes, and can for instance mea-
sure LC sensors, resistive sensors and capacitive sensors. LESENSE also includes a programmable
FSM which enables simple processing of measurement results without CPU intervention. LESENSE is
available in energy mode EM2, in addition to EM0 and EM1, making it ideal for sensor monitoring in
applications with a strict energy budget.
2.1.25 Backup Power Domain
The backup power domain is a separate power domain containing a Backup Real Time Counter, BURTC,
and a set of retention registers, available in all energy modes. This power domain can be configured to
automatically change power source to a backup battery when the main power drains out. The backup
power domain enables the EFM32GG842 to keep track of time and retain data, even if the main power
source should drain out.
2.1.26 Advanced Encryption Standard Accelerator (AES)
The AES accelerator performs AES encryption and decryption with 128-bit or 256-bit keys. Encrypting or
decrypting one 128-bit data block takes 52 HFCORECLK cycles with 128-bit keys and 75 HFCORECLK
