System Overview
3. System Overview
3.1 Introduction
The EZR32WG230 Wireless MCUs are the latest in Silicon Labs family of wireless MCUs delivering a high performance, low energy
wireless solution integrated into a small form factor package. By combining a high performance sub-GHz RF transceiver with an energy
efficient 32-bit ARM Cortex-M4, the EZR32WG family provides designers with the ultimate in flexibility with a family of pin-compatible
parts that scale from 64 to 256 kB of flash and support Silicon Labs EZRadio or EZRadioPRO transceivers. The ultra-low power operating modes and fast wake-up times combined with the low transmit and receive power consumption of the sub-GHz radio result in a
solution optimized for low power and battery powered applications. For a complete feature set and in-depth information on the modules,
the reader is referred to the EZR32WG Reference Manual.
The EZR32WG230 block diagram is shown below.
Figure 3.1. Block Diagram
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 EZR32 implementation of the Cortex-M4 is described in detail in EZR32 Cortex-M4 Reference Manual.
3.1.2 Debugging
These devices include 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 EZR32WG 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.

EZR32WG230 Data Sheet
System Overview
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 EZR32WG.
3.1.6 Energy Management Unit (EMU)
The Energy Management Unit (EMU) manages all the low energy modes (EM) in EZR32WG 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 EZR32WG. 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,
for example, 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 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 fast-mode 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.
3.1.11 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, and I2S devices.
3.1.12 Pre-Programmed UART 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.
3.1.13 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.

Rev. 1.1 | 4
EZR32WG230 Data Sheet
System Overview
3.1.14 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART)
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.
3.1.15 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.
3.1.16 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.
3.1.17 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.
3.1.18 Low Energy Timer (LETIMER)
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.
3.1.19 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.
3.1.20 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.
3.1.21 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.
3.1.22 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.
3.1.23 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.

EZR32WG230 Data Sheet
System Overview
3.1.24 Operational Amplifier (OPAMP)
The EZR32WG230 features 2 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.
3.1.25 Low Energy Sensor Interface (LESENSE)
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.
3.1.26 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 EZR32WG230 to keep track of time and retain data, even if
the main power source should drain out.
3.1.27 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).
3.1.28 General Purpose Input/Output (GPIO)
In the EZR32WG230, there are 41 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.

System Overview
3.1.29 EZRadio® and EZRadioPro® Transceivers
The EZR32WG family of devices is built using high-performance, low-current EZRadio and EZRadioPro RF transceivers covering the
sub-GHz frequency bands from 142 to 1050 MHz. These devices offer outstanding sensitivity of upto –133 dBm (using EZRadioPro)
while achieving extremely low active and standby current consumption. The EZR32WG devices using the EZRadioPro transceiver offer
frequency coverage in all major bands and include optimal phase noise, blocking, and selectivity performance for narrow band and licensed band applications, such as FCC Part 90 and 169 MHz wireless Mbus. The 69 dB adjacent channel selectivity with 12.5 kHz
channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrow band operation. The
active mode TX current consumption of 18 mA at +10 dBm and RX current of 10 mA coupled with extremely low standby current and
fast wake times is optimized for extended battery life in the most demanding applications. The EZR32WG devices can achieve up to
+27 dBm output power with built-in ramping control of a low-cost external FET. The devices can meet worldwide regulatory standards:
FCC, ETSI, and ARIB. All devices are designed to be compliant with 802.15.4g and WMbus smart metering standards. The devices are
highly flexible and can be programmed and configured via Simplicity Studio, available at www.silabs.com.
Communications between the radio and MCU are done over USART, PRS and IRQ, which requires the pins to be configured in the

System Overview
3.1.29.1 EZRadio® and EZRadioPRO® Transceivers GPIO Configuration
The EZRadio and EZRadioPRO Transceivers have 4 General Purpose Digital I/O pins. These GPIOs may be configured to perform
various radio-specific functions, including Clock Output, FIFO Status, POR, Wake-up Timer, TRSW, AntDiversity control, etc.
Two of the radio GPIO pins are directly connected to pins on the package (GPIO2 and GPIO3). However, the remaining two radio GPIO
pins (GPIO0 and GPIO1) connect internally on the EZR32WG to the pins shown in 3.1.29 EZRadio® and EZRadioPro® Transceivers.
These radio GPIOs may be routed to external package pins using the EZR32WG’s peripheral reflex system (PRS). Note that the maximum frequency of the GPIO pins routed through PRS pins may be limited to ~10 MHz.
Below is some example code illustrating how to configure the EZR32WG PRS system to output the radio GPIO0/GPIO1 functions to
EZR32WG pins PA0 / PA1, respectively. Note that the radio GPIO0/GPIO1 functions could also be connected to EZR32WG pins PF3/
PF4.

Note:
1. The TUNING field in the CMU_HFRCOCTRL register may be used to adjust the HFRCO frequency. There is enough adjustment
range to ensure that the frequency bands above 7 MHz will always have some overlap across supply voltage and temperature.
By using a stable frequency reference such as the LFXO or HFXO, a firmware calibration routine can vary the TUNING bits and
the frequency band to maintain the HFRCO frequency at any arbitrary value between 7 MHz and 28 MHz across operating conditions.

Note:
1. 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 -78 dBc for a full scale
input for chips that have the missing code issue.
2. Typical numbers given by abs(Mean) / (85 - 25).
3. Max number given by (abs(Mean) + 3x stddev) / (85 - 25).
The integral non-linearity (INL) and differential non-linearity parameters are explained in Figure 3.14 (p. 33) and Figure 3.15 (p. 33) ,
respectively.

Note:
General
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. This Land Pattern Design is based on the IPC-7351 guidelines.
Solder Mask Design
1. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is to be 60 μm
minimum, all the way around the pad.
Stencil Design
1. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder paste release.
2. The stencil thickness should be 0.125 mm (5 mils).
3. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pads.
4. A 4x4 array of 1.45 mm square openings on a 1.25 mm pitch should be used for the center ground pad.
Card Assembly
1. A No-Clean, Type-3 solder paste is recommended.
2. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for Small Body Components.
6.2 Soldering Information
The latest IPC/JEDEC J-STD-020 recommendations for Pb-Free reflow soldering should be followed.
The packages have a Moisture Sensitivity Level rating of 3, please see the latest IPC/JEDEC J-STD-033 standard for MSL description
and level 3 bake conditions. Place as many and as small as possible vias underneath each of the solder patches under the ground pad.
