System Overview

3.2.1 Antenna

Interface

The EFR32BG1 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 EFR32BG1 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 EFR32BG1 uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion mix-

er, 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 EFR32BG1 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 EFR32BG1 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 EFR32BG1. 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.

System Overview

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 EFR32BG1 including the Radio Controller (RAC), Peripheral Reflex System (PRS), and Low Energy peripherals.

3.2.6 RFSENSE

The RFSENSE module generates a system wakeup interrupt upon detection of wideband RF energy at the antenna interface, providing

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

EFR32BG1 has an extensive and flexible frame handling support for easy implementation of even complex communication protocols.

System Overview

3.3 Power

The EFR32BG1 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)

EFR32BG1 has up to 31 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 EFR32BG1. Individual enabling and disabling of clocks to all periph-

eral modules 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

oscillators.

3.5.2 Internal

and External Oscillators

The EFR32BG1 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.

System Overview

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 module 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 module. 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

System Overview

3.7.2 Low

Energy Universal Asynchronous Receiver/Transmitter (LEUART)

The unique LEUART

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 (I

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. 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 I

C module allows precise timing control of the transmission process and highly automated trans-

fers. 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 peripheral modules without software involvement.

Peripheral modules producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer periph-

erals 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 module implements a Cyclic Redundancy Check (CRC) function. It supports both 32-bit and 16-bit polynomials. The sup-

ported 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(2

), 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 modules 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.

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

maximum IO current specifications.

3. To operate above the IOVDD supply rail, over-voltage tolerance must be enabled according to the GPIO_Px_OVTDIS register.

Pins with over-voltage tolerance disabled have the same limits as Standard GPIO.

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

3. The system designer should consult the characteristic specs of the capacitor used on DECOUPLE to ensure its capacitance val-

ue stays within the specified bounds across temperature and DC bias.

4. VSCALE0 to VSCALE2 voltage change transitions occur at a rate of 10 mV / usec for approximately 20 usec. During this transi-

tion, peak currents will be dependent on the value of the DECOUPLE output capacitor, from 35 mA (with a 1 µF capacitor) to 70

mA (with a 2.7 µF capacitor).

5. The maximum limit on T

may be lower due to device self-heating, which depends on the power dissipation of the specific appli-

cation. T

(max) = T

(max) – (THETA

x PowerDissipation). Refer to the Absolute Maximum Ratings table and the Thermal

Characteristics table for T

tests place the Interferer center frequency at the Desired frequency ± 5 MHz on the channel raster, whereas the image rejection

test places the CW interferer near the image frequency of the Desired signal carrier, regardless of the channel raster.

5. Reference signal is defined as O-QPSK DSSS per 802.15.4, Frequency range = 2400-2483.5 MHz, Symbol rate = 62.5 ksym-

bols/s.

6. Reference sensitivity level is -85 dBm.

Note:

1. Derived from ADCCLK.

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

3. In ADCn_BIASPROG register.

4. In ADCn_CNTL register.

5. 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.

6. 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.

7. 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.

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.

Matching Networks

Typical RF matching network circuit diagrams are shown in

Figure 5.4 Typical 2.4 GHz RF impedance-matching network circuits on

page 102

for applications in the 2.4GHz band, and in

Figure 5.5 Typical Sub-GHz RF impedance-matching network circuits on page

102

for applications in the sub-GHz band. Application-specific component values can be found in the EFR32xG1 Reference Manual.

For low RF transmit power applications less than 13dBm, the two-element match is recommended. For OPNs supporting high power

RF transmission, the four-element match is recommended for high RF transmit power (> 13dBm).

6.6 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 6.4 APORT Connection Diagram on page 127

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.

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
