System Summary
3. System Summary
3.1 System Introduction
The EFM32 MCUs are the world’s most energy friendly microcontrollers. With a unique combination of the powerful 32-bit ARM CortexM4 with Floating-Point Unit (FPU), innovative low energy techniques, short wake-up time from energy saving modes, and a wide selection of peripherals, the EFM32WG 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 EFM32WG devices. For a complete feature set and in-depth information on the modules, the reader is referred to the EFM32WG Reference Manual.
A block diagram of the EFM32WG is shown in the following figure.

3.1.1 ARM Cortex-M4 Core
The ARM Cortex-M4 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-M4 is described in detail in EFM32WG Reference Manual.
3.1.2 Debug Interface (DBG)
This device includes hardware debug support through a 2-pin serial-wire debug interface and an Embedded 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.
3.1.3 Memory System Controller (MSC)
The Memory System Controller (MSC) is the program memory unit of the EFM32WG microcontroller. The flash memory is readable and
writable from both the Cortex-M4 and DMA. The flash memory is divided into two blocks; the main block and the information block.
Program code is normally written to the main block. Additionally, the information block is available for special user data and flash lock
bits. There is also a read-only page in the information block containing system and device calibration data. Read and write operations
are supported in the energy modes EM0 and EM1.

EFM32WG Data Sheet
System Summary
3.1.4 Direct Memory Access Controller (DMA)
The Direct Memory Access (DMA) controller performs memory operations independently of the CPU. This has the benefit of reducing
the energy consumption and the workload of the CPU, and enables the system to stay in low energy modes when moving for instance
data from the USART to RAM or from the External Bus Interface to a PWM-generating timer. The DMA controller uses the PL230
µDMA controller licensed from ARM.
3.1.5 Reset Management Unit (RMU)
The RMU is responsible for handling the reset functionality of the EFM32WG.
3.1.6 Energy Management Unit (EMU)
The Energy Management Unit (EMU) manage all the low energy modes (EM) in EFM32WG microcontrollers. Each energy mode manages if the CPU and the various peripherals are available. The EMU can also be used to turn off the power to unused SRAM blocks.
3.1.7 Clock Management Unit (CMU)
The Clock Management Unit (CMU) is responsible for controlling the oscillators and clocks on-board the EFM32WG. The CMU provides the capability to turn on and off the clock on an individual basis to all peripheral modules in addition to enable/disable and configure the available oscillators. The high degree of flexibility enables software to minimize energy consumption in any specific application
by not wasting power on peripherals and oscillators that are inactive.
3.1.8 Watchdog (WDOG)
The purpose of the watchdog timer is to generate a reset in case of a system failure, to increase application reliability. The failure may
e.g. be caused by an external event, such as an ESD pulse, or by a software failure.
3.1.9 Peripheral Reflex System (PRS)
The Peripheral Reflex System (PRS) system is a network which lets the different peripheral module communicate directly with each
other without involving the CPU. Peripheral modules which send out Reflex signals are called producers. The PRS routes these reflex
signals to consumer peripherals which apply actions depending on the data received. The format for the Reflex signals is not given, but
edge triggers and other functionality can be applied by the PRS.
3.1.10 External Bus Interface (EBI)
The External Bus Interface provides access to external parallel interface devices such as SRAM, FLASH, ADCs and LCDs. The interface is memory mapped into the address bus of the Cortex-M4. This enables seamless access from software without manually manipulating the IO settings each time a read or write is performed. The data and address lines are multiplexed in order to reduce the number
of pins required to interface the external devices. The timing is adjustable to meet specifications of the external devices. The interface is
limited to asynchronous devices.
3.1.11 TFT Direct Drive
The EBI contains a TFT controller which can drive a TFT via a 565 RGB interface. The TFT controller supports programmable display
and port sizes and offers accurate control of frequency and setup and hold timing. Direct Drive is supported for TFT displays which do
not have their own frame buffer. In that case TFT Direct Drive can transfer data from either on-chip memory or from an external memory device to the TFT at low CPU load. Automatic alpha-blending and masking is also supported for transfers through the EBI interface.
3.1.12 Universal Serial Bus Controller (USB)
The USB is a full-speed USB 2.0 compliant OTG host/device controller. The USB can be used in Device, On-the-go (OTG) Dual Role
Device or Host-only configuration. In OTG mode the USB supports both Host Negotiation Protocol (HNP) and Session Request Protocol (SRP). The device supports both fullspeed (12MBit/s) and low speed (1.5MBit/s) operation. The USB device includes an internal
dedicated Descriptor-Based Scatter/Gather DMA and supports up to 6 OUT endpoints and 6 IN endpoints, in addition to endpoint 0.
The on-chip PHY includes all OTG features, except for the voltage booster for supplying 5V to VBUS when operating as host.

System Summary
3.1.13 Inter-Integrated Circuit Interface (I2C)
The I2C module provides an interface between the MCU and a serial I2C-bus. It is capable of acting as both a master and a slave, and
supports multi-master buses. Both standard-mode, fast-mode and fastmode plus speeds are supported, allowing transmission rates all
the way from 10 kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also provided to allow implementation of an SMBus compliant
system. The interface provided to software by the I2C module, allows both fine-grained control of the transmission process and close to
automatic transfers. Automatic recognition of slave addresses is provided in all energy modes.
3.1.14 Universal Synchronous/Asynchronous Receiver/Transmitter (USART)
The Universal Synchronous Asynchronous serial Receiver and Transmitter (USART) is a very flexible serial I/O module. It supports full
duplex asynchronous UART communication as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with ISO7816 SmartCards, IrDA and I2S devices.
3.1.15 Pre-Programmed USB/UART Bootloader
The bootloader presented in application note AN0042 is pre-programmed in the device at factory. The bootloader enables users to program the EFM32 through a UART or a USB CDC class virtual UART without the need for a debugger. The autobaud feature, interface
and commands are described further in the application note.
3.1.16 Universal Asynchronous Receiver/Transmitter (UART)
The Universal Asynchronous serial Receiver and Transmitter (UART) is a very flexible serial I/O module. It supports full- and half-duplex asynchronous UART communication.
3.1.17 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART)
The unique LEUARTTM, the Low Energy UART, is a UART that allows two-way UART communication on a strict power budget. Only a
32.768 kHz clock is needed to allow UART communication up to 9600 baud/ s. The LEUART includes all necessary hardware support
to make asynchronous serial communication possible with minimum of software intervention and energy consumption.
3.1.18 Timer/Counter (TIMER)
The 16-bit general purpose Timer has 3 compare/capture channels for input capture and compare/Pulse- Width Modulation (PWM) output. TIMER0 also includes a Dead-Time Insertion module suitable for motor control applications.
3.1.19 Real Time Counter (RTC)
The Real Time Counter (RTC) contains a 24-bit counter and is clocked either by a 32.768 kHz crystal oscillator, or a 32.768 kHz RC
oscillator. In addition to energy modes EM0 and EM1, the RTC is also available in EM2. This makes it ideal for keeping track of time
since the RTC is enabled in EM2 where most of the device is powered down.
3.1.20 Backup Real Time Counter (BURTC)
The Backup Real Time Counter (BURTC) contains a 32-bit counter and is clocked either by a 32.768 kHz crystal oscillator, a 32.768
kHz RC oscillator or a 1 kHz ULFRCO. The BURTC is available in all Energy Modes and it can also run in backup mode, making it
operational even if the main power should drain out.
3.1.21 Low Energy Timer (LETIMER)
The unique LETIMERTM, the Low Energy Timer, is a 16-bit timer that is available in energy mode EM2 in addition to EM1 and EM0.
Because of this, it can be used for timing and output generation when most of the device is powered down, allowing simple tasks to be
performed while the power consumption of the system is kept at an absolute minimum. The LETIMER can be used to output a variety of
waveforms with minimal software intervention. It is also connected to the Real Time Counter (RTC), and can be configured to start
counting on compare matches from the RTC.
3.1.22 Pulse Counter (PCNT)
The Pulse Counter (PCNT) can be used for counting pulses on a single input or to decode quadrature encoded inputs. It runs off either
the internal LFACLK or the PCNTn_S0IN pin as external clock source. The module may operate in energy mode EM0 - EM3.

System Summary
3.1.23 Analog Comparator (ACMP)
The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indicating 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.
3.1.24 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.
3.1.25 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.
3.1.26 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.
3.1.27 Operational Amplifier (OPAMP)
The EFM32WG features up to 3 Operational Amplifiers. The Operational Amplifier is a versatile general purpose amplifier with rail-torail 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.
3.1.28 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 measure 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.
3.1.29 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 EFM32WG to keep track of time and retain data, even if the
main power source should drain out.
3.1.30 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 cycles with 256-bit keys. The AES module is an AHB slave
which enables efficient access to the data and key registers. All write accesses to the AES module must be 32-bit operations, i.e. 8- or
16-bit operations are not supported.
3.1.31 General Purpose Input/Output (GPIO)
In the EFM32WG, there are up to 93 General Purpose Input/Output (GPIO) pins, which are divided into ports with up to 16 pins each.
These pins can individually be configured as either an output or input. More advanced configurations like open-drain, filtering and drive
strength can also be configured individually for the pins. The GPIO pins can also be overridden by peripheral pin connections, like Timer PWM outputs or USART communication, which can be routed to several locations on the device. The GPIO supports up to 16 asynchronous external pin interrupts, which enables interrupts from any pin on the device. Also, the input value of a pin can be routed
through the Peripheral Reflex System to other peripherals.

3.1.32 Liquid Crystal Display Driver (LCD)
The LCD driver is capable of driving a segmented LCD display with up to 8x36 segments. A voltage boost function enables it to provide
the LCD display with higher voltage than the supply voltage for the device. In addition, an animation feature can run custom animations
on the LCD display without any CPU intervention. The LCD driver can also remain active even in Energy Mode 2 and provides a Frame
Counter interrupt that can wake-up the device on a regular basis for updating data.
