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 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.
2.1.3 Memory System Controller (MSC)

Preliminary
...the world's most energy friendly microcontrollers
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.
2.1.4 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.
2.1.5 Reset Management Unit (RMU)
The RMU is responsible for handling the reset functionality of the EFM32GG.
2.1.6 Energy Management Unit (EMU)
The Energy Management Unit (EMU) manage all the low energy modes (EM) in EFM32GG 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.
2.1.7 Clock Management Unit (CMU)
The Clock Management Unit (CMU) is responsible for controlling the oscillators and clocks on-board the
EFM32GG. 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.
2.1.8 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.
2.1.9 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.
2.1.10 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-M3. 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.
2.1.11 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
2012-09-11 - EFM32GG990FXX - d0046_Rev1.00

...the world's most energy friendly microcontrollers
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.
2.1.12 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/Garther 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.
2.1.13 Inter-Integrated Circuit Interface (I2C)
2
2
The I C module provides an interface between the MCU and a serial I C-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.
2
The interface provided to software by the I C 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.
2.1.14 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, I2S devices and IrDA devices.
2.1.15 Pre-Programmed Serial Bootloader
The bootloader presented in application note AN0003 is pre-programmed in the device at factory. Autobaud and destructive write are supported. The autobaud feature, interface and commands are described
further in the application note.
2.1.16 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.
2.1.17 Low Energy Universal Asynchronous Receiver/Transmitter
(LEUART)
TM
The unique LEUART , 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.
2.1.18 Timer/Counter (TIMER)
The 16-bit general purpose Timer has 3 compare/capture channels for input capture and compare/PulseWidth Modulation (PWM) output. TIMER0 also includes a Dead-Time Insertion module suitable for motor
control applications.

...the world's most energy friendly microcontrollers
2.1.19 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.
2.1.20 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.
2.1.21 Low Energy Timer (LETIMER)
TM
The unique LETIMER , 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.
2.1.22 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.
2.1.23 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.
2.1.24 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.
2.1.25 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.
2.1.26 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.
2.1.27 Operational Amplifier (OPAMP)
The EFM32GG990 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.
2.1.28 Low Energy Sensor Interface (LESENSE)
TM
The Low Energy Sensor Interface (LESENSE ), 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.
2.1.29 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 EFM32GG990 to keep track of time and retain data, even if the main power
source should drain out.
2.1.30 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.
2.1.31 General Purpose Input/Output (GPIO)
In the EFM32GG990, there are 86 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
advances 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.
2.1.32 Liquid Crystal Display Driver (LCD)
The LCD driver is capable of driving a segmented LCD display with up to 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.

On the average every ADC will have one missing code, most likely to appear around 2048 +/- n*512 where n can be a value in
the set {-3, -2, -1, 1, 2, 3}. There will be no missing code around 2048, and in spite of the missing code the ADC will be monotonic
at all times so that a response to a slowly increasing input will always be a slowly increasing output. Around the one code that is
missing, the neighbour codes will look wider in the DNL plot. The spectra will show spurs on the level of -78dBc for a full scale
input for chips that have the missing code issue.

The integral non-linearity (INL) and differential non-linearity parameters are explained in Figure 3.13 (p.
