The Mighty Gecko family features a highly configurable radio transceiver supporting a wide range of wireless protocols, including Zig-

bee, Thread, BLE and proprietary.

System Overview

silabs.com | Building a more connected world. Rev. 1.4 | 9

3.2.1 Antenna Interface

The EFR32MG1 family includes devices which support both single-band and dual-band RF communication over separate physical RF

interfaces.

The 2.4 GHz antenna interface consists of two pins (2G4RF_IOP and 2G4RF_ION) that interface directly to the on-chip BALUN. The

2G4RF_ION pin should be grounded externally.

The sub-GHz antenna interface consists of a differential transmit interface (pins SUBGRF_OP and SUBGRF_ON) and a differential re-

ceive interface (pinsSUBGRF_IP and SUBGRF_IN).

The external components and power supply connections for the antenna interface typical applications are shown in the RF Matching

Networks section.

3.2.2 Fractional-N Frequency Synthesizer

The EFR32MG1 contains a high performance, low phase noise, fully integrated fractional-N frequency synthesizer. The synthesizer is

used in receive mode to generate the LO frequency used by the down-conversion mixer. It is also used in transmit mode to directly

generate the modulated RF carrier.

The fractional-N architecture provides excellent phase noise performance combined with frequency resolution better than 100 Hz, with

low energy consumption. The synthesizer has fast frequency settling which allows very short receiver and transmitter wake up times to

optimize system energy consumption.

3.2.3 Receiver Architecture

The EFR32MG1 uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion

mixer, employing a crystal reference. The I/Q signals are further filtered and amplified before being sampled by the IF analog-to-digital

converter (IFADC).

The IF frequency is configurable from 150 kHz to 1371 kHz. The IF can further be configured for high-side or low-side injection, provid-

ing flexibility with respect to known interferers at the image frequency.

The Automatic Gain Control (AGC) module adjusts the receiver gain to optimize performance and avoid saturation for excellent selec-

tivity and blocking performance. The 2.4 GHz radio is calibrated at production to improve image rejection performance. The sub-GHz

radio can be calibrated on-demand by the user for the desired frequency band.

Demodulation is performed in the digital domain. The demodulator performs configurable decimation and channel filtering to allow re-

ceive bandwidths ranging from 0.1 to 2530 kHz. High carrier frequency and baud rate offsets are tolerated by active estimation and

compensation. Advanced features supporting high quality communication under adverse conditions include forward error correction by

block and convolutional coding as well as Direct Sequence Spread Spectrum (DSSS) for 2.4 GHz and sub-GHz bands.

A Received Signal Strength Indicator (RSSI) is available for signal quality metrics, for level-based proximity detection, and for RF chan-

nel access by Collision Avoidance (CA) or Listen Before Talk (LBT) algorithms. An RSSI capture value is associated with each received

frame and the dynamic RSSI measurement can be monitored throughout reception.

The EFR32MG1 features integrated support for antenna diversity to mitigate the problem of frequency-selective fading due to multipath

propagation and improve link budget. Support for antenna diversity is available for specific PHY configurations in 2.4 GHz and sub-GHz

bands. Internal configurable hardware controls an external switch for automatic switching between antennae during RF receive detec-

tion operations.

Note: Due to the shorter preamble of 802.15.4 and BLE packets, RX diversity is not supported.

3.2.4 Transmitter Architecture

The EFR32MG1 uses a direct-conversion transmitter architecture. For constant envelope modulation formats, the modulator controls

phase and frequency modulation in the frequency synthesizer. Transmit symbols or chips are optionally shaped by a digital shaping

filter. The shaping filter is fully configurable, including the BT product, and can be used to implement Gaussian or Raised Cosine shap-

ing.

Carrier Sense Multiple Access - Collision Avoidance (CSMA-CA) or Listen Before Talk (LBT) algorithms can be automatically timed by

the EFR32MG1. These algorithms are typically defined by regulatory standards to improve inter-operability in a given bandwidth be-

tween devices that otherwise lack synchronized RF channel access.

3.2.5 Wake on Radio

The Wake on Radio feature allows flexible, autonomous RF sensing, qualification, and demodulation without required MCU activity, us-

ing a subsystem of the EFR32MG1 including the Radio Controller (RAC), Peripheral Reflex System (PRS), and Low Energy peripher-

als.

3.2.6 RFSENSE

The RFSENSE peripheral generates a system wakeup interrupt upon detection of wideband RF energy at the antenna interface, provid-

ing true RF wakeup capabilities from low energy modes including EM2, EM3 and EM4.

RFSENSE triggers on a relatively strong RF signal and is available in the lowest energy modes, allowing exceptionally low energy con-

sumption. RFSENSE does not demodulate or otherwise qualify the received signal, but software may respond to the wakeup event by

enabling normal RF reception.

Various strategies for optimizing power consumption and system response time in presence of false alarms may be employed using

available timer peripherals.

3.2.7 Flexible Frame Handling

EFR32MG1 has an extensive and flexible frame handling support for easy implementation of even complex communication protocols.

The Frame Controller (FRC) supports all low level and timing critical tasks together with the Radio Controller and Modulator/Demodula-

tor:

• Highly adjustable preamble length

• Up to 2 simultaneous synchronization words, each up to 32 bits and providing separate interrupts

• Frame disassembly and address matching (filtering) to accept or reject frames

• Automatic ACK frame assembly and transmission

• Fully flexible CRC generation and verification:

• Multiple CRC values can be embedded in a single frame

• 8, 16, 24 or 32-bit CRC value

• Configurable CRC bit and byte ordering

• Selectable bit-ordering (least significant or most significant bit first)

• Optional data whitening

• Optional Forward Error Correction (FEC), including convolutional encoding / decoding and block encoding / decoding

• Half rate convolutional encoder and decoder with constraint lengths from 2 to 7 and optional puncturing

• Optional symbol interleaving, typically used in combination with FEC

• Symbol coding, such as Manchester or DSSS, or biphase space encoding using FEC hardware

• UART encoding over air, with start and stop bit insertion / removal

• Test mode support, such as modulated or unmodulated carrier output

• Received frame timestamping

3.2.8 Packet and State Trace

The EFR32MG1 Frame Controller has a packet and state trace unit that provides valuable information during the development phase. It

features:

• Non-intrusive trace of transmit data, receive data and state information

• Data observability on a single-pin UART data output, or on a two-pin SPI data output

• Configurable data output bitrate / baudrate

• Multiplexed transmitted data, received data and state / meta information in a single serial data stream

3.2.9 Data Buffering

The EFR32MG1 features an advanced Radio Buffer Controller (BUFC) capable of handling up to 4 buffers of adjustable size from 64

3.2.10 Radio Controller (RAC)

The Radio Controller controls the top level state of the radio subsystem in the EFR32MG1. It performs the following tasks:

• Precisely-timed control of enabling and disabling of the receiver and transmitter circuitry

• Run-time calibration of receiver, transmitter and frequency synthesizer

• Detailed frame transmission timing, including optional LBT or CSMA-CA

3.2.11 Random Number Generator

The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain.

The data is suitable for use in cryptographic applications.

Output from the random number generator can be used either directly or as a seed or entropy source for software-based random num-

ber generator algorithms such as Fortuna.

3.3 Power

The EFR32MG1 has an Energy Management Unit (EMU) and efficient integrated regulators to generate internal supply voltages. Only a

single external supply voltage is required, from which all internal voltages are created. An optional integrated DC-DC buck regulator can

be utilized to further reduce the current consumption. The DC-DC regulator requires one external inductor and one external capacitor.

AVDD and VREGVDD need to be 1.85 V or higher for the MCU to operate across all conditions; however the rest of the system will

operate down to 1.62 V, including the digital supply and I/O. This means that the device is fully compatible with 1.8 V components.

Running from a sufficiently high supply, the device can use the DC-DC to regulate voltage not only for itself, but also for other PCB

components, supplying up to a total of 200 mA.

3.3.1 Energy Management Unit (EMU)

The Energy Management Unit manages transitions of energy modes in the device. Each energy mode defines which peripherals and

features are available and the amount of current the device consumes. The EMU can also be used to turn off the power to unused RAM

blocks, and it contains control registers for the DC-DC regulator and the Voltage Monitor (VMON). The VMON is used to monitor multi-

ple supply voltages. It has multiple channels which can be programmed individually by the user to determine if a sensed supply has

fallen below a chosen threshold.

3.3.2 DC-DC Converter

The DC-DC buck converter covers a wide range of load currents and provides up to 90% efficiency in energy modes EM0, EM1, EM2

and EM3, and can supply up to 200 mA to the device and surrounding PCB components. Patented RF noise mitigation allows operation

of the DC-DC converter without degrading sensitivity of radio components. Protection features include programmable current limiting,

short-circuit protection, and dead-time protection. The DC-DC converter may also enter bypass mode when the input voltage is too low

for efficient operation. In bypass mode, the DC-DC input supply is internally connected directly to its output through a low resistance

switch. Bypass mode also supports in-rush current limiting to prevent input supply voltage droops due to excessive output current tran-

sients.

3.4 General Purpose Input/Output (GPIO)

EFR32MG1 has up to 32 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or input.

More advanced configurations including open-drain, open-source, and glitch-filtering can be configured for each individual GPIO pin.

The GPIO pins can be overridden by peripheral connections, like SPI communication. Each peripheral connection can be routed to sev-

eral GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripherals.

The GPIO subsystem supports asynchronous external pin interrupts.

3.5 Clocking

3.5.1 Clock Management Unit (CMU)

The Clock Management Unit controls oscillators and clocks in the EFR32MG1. Individual enabling and disabling of clocks to all periph-

erals is performed by the CMU. The CMU also controls enabling and configuration of the oscillators. A high degree of flexibility allows

software to optimize energy consumption in any specific application by minimizing power dissipation in unused peripherals and oscilla-

tors.

3.5.2 Internal and External Oscillators

The EFR32MG1 supports two crystal oscillators and fully integrates four RC oscillators, listed below.

• A high frequency crystal oscillator (HFXO) with integrated load capacitors, tunable in small steps, provides a precise timing refer-

ence for the MCU. Crystal frequencies in the range from 38 to 40 MHz are supported. An external clock source such as a TCXO can

also be applied to the HFXO input for improved accuracy over temperature.

• A 32.768 kHz crystal oscillator (LFXO) provides an accurate timing reference for low energy modes.

• An integrated high frequency RC oscillator (HFRCO) is available for the MCU system, when crystal accuracy is not required. The

HFRCO employs fast startup at minimal energy consumption combined with a wide frequency range.

• An integrated auxilliary high frequency RC oscillator (AUXHFRCO) is available for timing the general-purpose ADC and the Serial

Wire Viewer port with a wide frequency range.

• An integrated low frequency 32.768 kHz RC oscillator (LFRCO) can be used as a timing reference in low energy modes, when crys-

tal accuracy is not required.

• An integrated ultra-low frequency 1 kHz RC oscillator (ULFRCO) is available to provide a timing reference at the lowest energy con-

sumption in low energy modes.

3.6 Counters/Timers and PWM

3.6.1 Timer/Counter (TIMER)

TIMER peripherals keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the

PRS system. The core of each TIMER is a 16-bit counter with up to 4 compare/capture channels. Each channel is configurable in one

of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output

reflects the comparison of the counter to a programmed threshold value. In PWM mode, the TIMER supports generation of pulse-width

modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers, with optional

dead-time insertion available in timer unit TIMER_0 only.

3.6.2 Real Time Counter and Calendar (RTCC)

The Real Time Counter and Calendar (RTCC) is a 32-bit counter providing timekeeping in all energy modes. The RTCC includes a

Binary Coded Decimal (BCD) calendar mode for easy time and date keeping. The RTCC can be clocked by any of the on-board oscilla-

tors with the exception of the AUXHFRCO, and it is capable of providing system wake-up at user defined instances. When receiving

frames, the RTCC value can be used for timestamping. The RTCC includes 128 bytes of general purpose data retention, allowing easy

and convenient data storage in all energy modes down to EM4H.

3.6.3 Low Energy Timer (LETIMER)

The unique LETIMER is a 16-bit timer that is available in energy mode EM2 Deep Sleep in addition to EM1 Sleep and EM0 Active. This

allows it to 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 wave-

forms with minimal software intervention. The LETIMER is connected to the Real Time Counter and Calendar (RTCC), and can be con-

figured to start counting on compare matches from the RTCC.

3.6.4 Ultra Low Power Wake-up Timer (CRYOTIMER)

The CRYOTIMER is a 32-bit counter that is capable of running in all energy modes. It can be clocked by either the 32.768 kHz crystal

oscillator (LFXO), the 32.768 kHz RC oscillator (LFRCO), or the 1 kHz RC oscillator (ULFRCO). It can provide periodic Wakeup events

and PRS signals which can be used to wake up peripherals from any energy mode. The CRYOTIMER provides a wide range of inter-

rupt periods, facilitating flexible ultra-low energy operation.

3.6.5 Pulse Counter (PCNT)

The Pulse Counter (PCNT) peripheral can be used for counting pulses on a single input or to decode quadrature encoded inputs. The

clock for PCNT is selectable from either an external source on pin PCTNn_S0IN or from an internal timing reference, selectable from

among any of the internal oscillators, except the AUXHFRCO. The peripheral may operate in energy mode EM0 Active, EM1 Sleep,

EM2 Deep Sleep, and EM3 Stop.

3.6.6 Watchdog Timer (WDOG)

The watchdog timer can act both as an independent watchdog or as a watchdog synchronous with the CPU clock. It has windowed

monitoring capabilities, and can generate a reset or different interrupts depending on the failure mode of the system. The watchdog can

also monitor autonomous systems driven by PRS.

3.7 Communications and Other Digital Peripherals

3.7.1 Universal Synchronous/Asynchronous Receiver/Transmitter (USART)

The Universal Synchronous/Asynchronous Receiver/Transmitter is a flexible serial I/O interface. It supports full duplex asynchronous

UART communication with hardware flow control as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with devices sup-

porting:

• ISO7816 SmartCards

• IrDA

•I2S

3.7.2 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART)

The unique LEUARTTM provides 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. The LEUART includes all necessary hardware to make asynchronous serial communication

possible with a minimum of software intervention and energy consumption.

3.7.3 Inter-Integrated Circuit Interface (I2C)

The I2C interface enables communication 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. Standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates

from 10 kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also available, allowing implementation of an SMBus-compliant system.

The interface provided to software by the I2C peripheral allows precise timing control of the transmission process and highly automated

transfers. Automatic recognition of slave addresses is provided in active and low energy modes.

3.7.4 Peripheral Reflex System (PRS)

The Peripheral Reflex System provides a communication network between different peripherals without software involvement. Peripher-

als producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer peripherals, which in

turn perform actions in response. Edge triggers and other functionality such as simple logic operations (AND, OR, NOT) can be applied

by the PRS to the signals. The PRS allows peripheral to act autonomously without waking the MCU core, saving power.

3.8 Security Features

3.8.1 GPCRC (General Purpose Cyclic Redundancy Check)

The GPCRC block implements a Cyclic Redundancy Check (CRC) function. It supports both 32-bit and 16-bit polynomials. The suppor-

ted 32-bit polynomial is 0x04C11DB7 (IEEE 802.3), while the 16-bit polynomial can be programmed to any value, depending on the

needs of the application.

3.8.2 Crypto Accelerator (CRYPTO)

The Crypto Accelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. EFR32 devices sup-

port AES encryption and decryption with 128- or 256-bit keys, ECC over both GF(P) and GF(2m), SHA-1 and SHA-2 (SHA-224 and

SHA-256).

Supported block cipher modes of operation for AES include: ECB, CTR, CBC, PCBC, CFB, OFB, GCM, CBC-MAC, GMAC and CCM.

Supported ECC NIST recommended curves include P-192, P-224, P-256, K-163, K-233, B-163 and B-233.

The CRYPTO block is tightly linked to the Radio Buffer Controller (BUFC) enabling fast and efficient autonomous cipher operations on

data buffer content. It allows fast processing of GCM (AES), ECC and SHA with little CPU intervention.

CRYPTO also provides trigger signals for DMA read and write operations.

3.9 Analog

3.9.1 Analog Port (APORT)

The Analog Port (APORT) is an analog interconnect matrix allowing access to many analog peripherals on a flexible selection of pins.

Each APORT bus consists of analog switches connected to a common wire. Since many clients can operate differentially, buses are

grouped by X/Y pairs.

3.9.2 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 high-

er. Inputs are selected from among internal references and external pins. The tradeoff between response time and current consumption

is configurable by software. Two 6-bit reference dividers allow for a wide range of internally-programmable reference sources. The

ACMP can also be used to monitor the supply voltage. An interrupt can be generated when the supply falls below or rises above the

programmable threshold.

3.9.3 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 1 Msps. The output

sample resolution is configurable and additional resolution is possible using integrated hardware for averaging over multiple samples.

The ADC includes integrated voltage references and an integrated temperature sensor. Inputs are selectable from a wide range of

sources, including pins configurable as either single-ended or differential.

3.9.4 Digital to Analog Current Converter (IDAC)

The IDAC can source or sink a configurable constant current. This current can be driven on an output pin or routed to the selected ADC

input pin for capacitive sensing. The full-scale current is programmable between 0.05 µA and 64 µA with several ranges consisting of

various step sizes.

3.10 Reset Management Unit (RMU)

The RMU is responsible for handling reset of the EFR32MG1. A wide range of reset sources are available, including several power

supply monitors, pin reset, software controlled reset, core lockup reset, and watchdog reset.

3.11 Core and Memory

3.11.1 Processor Core

The ARM Cortex-M processor includes a 32-bit RISC processor integrating the following features and tasks in the system:

• ARM Cortex-M4 RISC processor achieving 1.25 Dhrystone MIPS/MHz

• Memory Protection Unit (MPU) supporting up to 8 memory segments

• Up to 256 kB flash program memory

• Up to 32 kB RAM data memory

• Configuration and event handling of all peripherals

• 2-pin Serial-Wire debug interface

3.11.2 Memory System Controller (MSC)

The Memory System Controller (MSC) is the program memory unit of the microcontroller. The flash memory is readable and writable

from both the Cortex-M 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, whereas 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 en-

ergy modes EM0 Active and EM1 Sleep.

3.11.3 Linked Direct Memory Access Controller (LDMA)

The Linked Direct Memory Access (LDMA) controller allows the system to perform memory operations independently of software. This

reduces both energy consumption and software workload. The LDMA allows operations to be linked together and staged, enabling so-

phisticated operations to be implemented.

Note:

1. When a GPIO pin is routed to the analog module through the APORT, the maximum voltage = IOVDD.

2. Valid for IOVDD in valid operating range or when IOVDD is undriven (high-Z). If IOVDD is connected to a low-impedance source

below the valid operating range (e.g. IOVDD shorted to VSS), the pin voltage maximum is IOVDD + 0.3 V, to avoid exceeding the

2. VREGVDD must be tied to AVDD. Both VREGVDD and AVDD minimum voltages must be satisfied for the part to operate.

3. The minimum voltage required in bypass mode is calculated using RBYP from the DCDC specification table. Requirements for

other loads can be calculated as VDVDD_min+ILOAD * RBYP_max.

Note:

1. The absolute voltage allowed at any ADC input is dictated by the power rail supplied to on-chip circuitry, and may be lower than

the effective full scale voltage. All ADC inputs are limited to the ADC supply (AVDD or DVDD depending on

EMU_PWRCTRL_ANASW). Any ADC input routed through the APORT will further be limited by the IOVDD supply to the pin.

2. PSRR is referenced to AVDD when ANASW=0 and to DVDD when ANASW=1 in EMU_PWRCTRL.

3. In ADCn_CNTL register.

4. In ADCn_BIASPROG register.

5. Derived from ADCCLK.

6. Internal reference option used corresponds to selection 2V5 in the SINGLECTRL_REF or SCANCTRL_REF register field. The

differential input range with this configuration is ± 1.25 V. Typical value is characterized using full-scale sine wave input. Minimum

value is production-tested using sine wave input at 1.5 dB lower than full scale.

7. External reference is 1.25 V applied externally to ADCnEXTREFP, with the selection CONF in the SINGLECTRL_REF or

SCANCTRL_REF register field and VREFP in the SINGLECTRLX_VREFSEL or SCANCTRLX_VREFSEL field. The differential

input range with this configuration is ± 1.25 V.

Figure 5.1. EFR32MG1 Typical Application Circuit: Direct Supply Configuration without DC-DC converter

Typical power supply circuits using the internal DC-DC converter are shown below. The MCU operates from the DC-DC converter sup-

ply. For low RF transmit power applications less than 13dBm, the RF PA may be supplied by the DC-DC converter. For OPNs support-

ing high power RF transmission, the RF PA must be directly supplied by VDD for RF transmit power greater than 13 dBm.

6.6 Alternate Functionality Overview

A wide selection of alternate functionality is available for multiplexing to various pins. The following table shows the name of the alter-

nate functionality in the first column, followed by columns showing the possible LOCATION bitfield settings and the associated GPIO

pin. Refer to 6.5 GPIO Functionality Table for a list of functions available on each GPIO pin.

Note: Some functionality, such as analog interfaces, do not have alternate settings or a LOCATION bitfield. In these cases, the pinout

is shown in the column corresponding to LOCATION 0.

6.7 Analog Port (APORT) Client Maps

The Analog Port (APORT) is an infrastructure used to connect chip pins with on-chip analog clients such as analog comparators, ADCs,

DACs, etc. The APORT consists of a set of shared buses, switches, and control logic needed to configurably implement the signal rout-

ing. Figure 6.5 APORT Connection Diagram on page 130 shows the APORT routing for this device family (note that available features

may vary by part number). A complete description of APORT functionality can be found in the Reference Manual.

Figure 6.5. APORT Connection Diagram

Client maps for each analog circuit using the APORT are shown in the following tables. The maps are organized by bus, and show the

peripheral's port connection, the shared bus, and the connection from specific bus channel numbers to GPIO pins.

In general, enumerations for the pin selection field in an analog peripheral's register can be determined by finding the desired pin con-

nection in the table and then combining the value in the Port column (APORT__), and the channel identifier (CH__). For example, if pin

PF7 is available on port APORT2X as CH23, the register field enumeration to connect to PF7 would be APORT2XCH23. The shared

bus used by this connection is indicated in the Bus column.
