EFR32FG13 Flex Gecko Proprietary Protocol SoC Family Data Sheet
System Overview
3.2.1 Antenna Interface
The EFR32FG13 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 EFR32FG13 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 EFR32FG13 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) block adjusts the receiver gain to optimize performance and avoid saturation for excellent selectivity
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 EFR32FG13 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 EFR32FG13 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 EFR32FG13. 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 EFR32FG13 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
EFR32FG13 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

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 EFR32FG13 features an advanced Radio Buffer Controller (BUFC) capable of handling up to 4 buffers of adjustable size from 64
bytes to 4096 bytes. Each buffer can be used for RX, TX or both. The buffer data is located in RAM, enabling zero-copy operations.

EFR32FG13 Flex Gecko Proprietary Protocol SoC Family Data Sheet
System Overview
3.3 Power
The EFR32FG13 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 capaci-
tor.
The EFR32FG13 device family includes support for internal supply voltage scaling, as well as two different power domains groups for
peripherals. These enhancements allow for further supply current reductions and lower overall power consumption.
AVDD and VREGVDD need to be 1.8 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.
3.3.3 Power Domains
The EFR32FG13 has two peripheral power domains for operation in EM2 and EM3. If all of the peripherals in a peripheral power do-
main are configured as unused, the power domain for that group will be powered off in the low-power mode, reducing the overall cur-
rent consumption of the device.

3.4 General Purpose Input/Output (GPIO)
EFR32FG13 has up to 32 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or in-
put. 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
several GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripher-
als. The GPIO subsystem supports asynchronous external pin interrupts.

System Overview
3.5 Clocking
3.5.1 Clock Management Unit (CMU)
The Clock Management Unit controls oscillators and clocks in the EFR32FG13. 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 EFR32FG13 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 Wide Timer/Counter (WTIMER)
WTIMER peripherals function just as TIMER peripherals, but are 32 bits wide. They keep track of timing, count events, generate PWM
outputs and trigger timed actions in other peripherals through the PRS system. The core of each WTIMER is a 32-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 thresh-
old value. In PWM mode, the WTIMER 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 WTIMER_0 only.
3.6.3 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.
A secondary RTC is used by the RF protocol stack for event scheduling, leaving the primary RTCC block available exclusively for appli-
cation software.

The unique LETIMER is a 16-bit timer that is available in energy mode EM0 Active, EM1 Sleep, EM2 Deep Sleep, and EM3 Stop. 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
configured to start counting on compare matches from the RTCC.
3.6.5 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.
3.6.6 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.
3.6.7 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:

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.

ble sensors. By controlling the analog comparators, ADC, 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 finite state machine 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.
3.8 Security Features
3.8.1 General Purpose Cyclic Redundancy Check (GPCRC)
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).

The CRYPTO1 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.
3.8.3 True Random Number Generator (TRNG)
The TRNG is a non-deterministic random number generator based on a full hardware solution. The TRNG is validated with NIST800-22
and AIS-31 test suites as well as being suitable for FIPS 140-2 certification (for the purposes of cryptographic key generation).
3.8.4 Security Management Unit (SMU)
The Security Management Unit (SMU) allows software to set up fine-grained security for peripheral access, which is not possible in the
Memory Protection Unit (MPU). Peripherals may be secured by hardware on an individual basis, such that only priveleged accesses to
the peripheral's register interface will be allowed. When an access fault occurs, the SMU reports the specific peripheral involved and
can optionally generate an interrupt.
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.

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 Capacitive Sense (CSEN)
The CSEN peripheral is a dedicated Capacitive Sensing block for implementing touch-sensitive user interface elements such a
switches and sliders. The CSEN peripheral uses a charge ramping measurement technique, which provides robust sensing even in
adverse conditions including radiated noise and moisture. The peripheral can be configured to take measurements on a single port pin
or scan through multiple pins and store results to memory through DMA. Several channels can also be shorted together to measure the
combined capacitance or implement wake-on-touch from very low energy modes. Hardware includes a digital accumulator and an aver-
aging filter, as well as digital threshold comparators to reduce software overhead.
3.9.5 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.
3.9.6 Digital to Analog Converter (VDAC)
The Digital to Analog Converter (VDAC) can convert a digital value to an analog output voltage. The VDAC is a fully differential, 500
ksps, 12-bit converter. The opamps are used in conjunction with the VDAC, to provide output buffering. One opamp is used per single-
ended channel, or two opamps are used to provide differential outputs. The VDAC may be used for a number of different applications
such as sensor interfaces or sound output. The VDAC can generate high-resolution analog signals while the MCU is operating at low
frequencies and with low total power consumption. Using DMA and a timer, the VDAC can be used to generate waveforms without any
CPU intervention. The VDAC is available in all energy modes down to and including EM3.

The opamps are low power amplifiers with a high degree of flexibility targeting a wide variety of standard opamp application areas, and
are available down to EM3. With flexible built-in programming for gain and interconnection they can be configured to support multiple
common opamp functions. All pins are also available externally for filter configurations. Each opamp has a rail to rail input and a rail to
rail output. They can be used in conjunction with the VDAC peripheral or in stand-alone configurations. The opamps save energy, PCB
space, and cost as compared with standalone opamps because they are integrated on-chip.

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

1. When a GPIO pin is routed to the analog block 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.

Note:
1. The maximum limit on TA may be lower due to device self-heating, which depends on the power dissipation of the specific appli-
cation. TA (max) = TJ (max) - (THETAJA x PowerDissipation). Refer to the Absolute Maximum Ratings table and the Thermal
Characteristics table for TJ and THETAJA
.
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
.
4. When the CSEN peripheral is used with chopping enabled (CSEN_CTRL_CHOPEN = ENABLE), IOVDD must be equal to AVDD.
5. 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.
6. 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).

Note:
1. Due to internal dropout, the DC-DC output will never be able to reach its input voltage, VVREGVDD
.
2. LP mode controller is a hysteretic controller that maintains the output voltage within the specified limits.
3. LPCMPBIASEMxx refers to either LPCMPBIASEM234H in the EMU_DCDCMISCCTRL register or LPCMPBIASEM01 in the
EMU_DCDCLOEM01CFG register, depending on the energy mode.
4. Drive levels are defined by configuration of the PFETCNT and NFETCNT registers. Light Drive: PFETCNT=NFETCNT=3; Medi-
um Drive: PFETCNT=NFETCNT=7; Heavy Drive: PFETCNT=NFETCNT=15.
5. Output voltage under/over-shoot and regulation are specified with CDCDC 4.7 µF. Different settings for DCDCLNCOMPCTRL
must be used if CDCDC is lower than 4.7 µF. See Application Note AN0948 for details.

Note:
1. Time from wake up request until first instruction is executed. Wakeup results in device reset.
2. Scaling up from VSCALE0 to VSCALE2 requires approximately 30.3 µs + 28 HFCLKs.
3. VSCALE0 to VSCALE2 voltage change transitions occur at a rate of 10 mV/µs for approximately 20 µs. During this transition,
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).
4. Scaling down from VSCALE2 to VSCALE0 requires approximately 2.8 µs + 29 HFCLKs.

bols/s.
2. Reference sensitivity level is -85 dBm.
3. Filter is characterized as a symmetric bandpass centered on the adjacent channel having a 3dB bandwidth of 4.6 MHz and stop-
band rejection better than 26 dB beyond 3.15 MHz from the adjacent carrier.
4. Due to low-IF frequency, there is some overlap of adjacent channel and image channel bands. Adjacent channel CW blocker
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. This is an IEEE 802.11b/g ERP-PBCC 22 MBit/s signal as defined by the IEEE 802.11 specification and IEEE 802.11g adden-
dum.

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_CTRL 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.

Note:
1. In differential mode, the output is defined as the difference between two single-ended outputs. Absolute voltage on each output is
limited to the single-ended range.
2. Supply current specifications are for VDAC circuitry operating with static output only and do not include current required to drive
the load.
3. Current from HFPERCLK is dependent on HFPERCLK frequency. This current contributes to the total supply current used when
the clock to the DAC peripheral is enabled in the CMU.
4. PSRR calculated as 20 * log10(ΔVDD / ΔVOUT), VDAC output at 90% of full scale
5. Entire range is monotonic and has no missing codes.
6. Gain is calculated by measuring the slope from 10% to 90% of full scale. Offset is calculated by comparing actual VDAC output at
10% of full scale to ideal VDAC output at 10% of full scale with the measured gain.

2. The IDAC is supplied by either AVDD, DVDD, or IOVDD based on the setting of ANASW in the EMU_PWRCTRL register and
PWRSEL in the IDAC_CTRL register. Setting PWRSEL to 1 selects IOVDD. With PWRSEL cleared to 0, ANASW selects be-
tween AVDD (0) and DVDD (1).

Note:
1. Current is specified with a total external capacitance of 33 pF per channel. Average current is dependent on how long the periph-
eral is actively sampling channels within the scan period, and scales with the number of samples acquired. Supply current for a
specific application can be estimated by multiplying the current per sample by the total number of samples per period (total_cur-
rent = single_sample_current * (number_of_channels * accumulation)).

1. Specified configuration for Unit gain buffer configuration is: INCBW = 0, HCMDIS = 0, RESINSEL = DISABLE. VINPUT = 0.5 V,
VOUTPUT = 0.5 V.
2. Specified configuration for 3X-Gain configuration is: INCBW = 1, HCMDIS = 1, RESINSEL = VSS, VINPUT = 0.5 V, VOUTPUT = 1.5
V. Nominal voltage gain is 3.
3. If the maximum CLOAD is exceeded, an isolation resistor is required for stability. See AN0038 for more information.
4. Current into the load resistor is excluded. When the OPAMP is connected with closed-loop gain > 1, there will be extra current to
drive the resistor feedback network. The internal resistor feedback network has total resistance of 143.5 kOhm, which will cause
another ~10 µA current when the OPAMP drives 1.5 V between output and ground.
5. In unit gain connection, UGF is the gain-bandwidth product of the OPAMP. In 3x Gain connection, UGF is the gain-bandwidth
product of the OPAMP and 1/3 attenuation of the feedback network.
6. Step between 0.2V and VOPA-0.2V, 10%-90% rising/falling range.
7. When INCBW is set to 1 the OPAMP bandwidth is increased. This is allowed only when the non-inverting close-loop gain is ≥ 3,
or the OPAMP may not be stable.
8. From enable to output settled. In sample-and-off mode, RC network after OPAMP will contribute extra delay. Settling error < 1mV.
9. When HCMDIS=1 and input common mode transitions the region from VOPA-1.4V to VOPA-1V, input offset will change. PSRR
and CMRR specifications do not apply to this transition region.

1. Supply current increase that occurs when an analog peripheral requests access to APORT. This current is not included in repor-
ted peripheral currents. Additional peripherals requesting access to APORT do not incur further current.
2. Specified current is for continuous APORT operation. In applications where the APORT is not requested continuously (e.g. peri-
odic ACMP requests from LESENSE in EM2), the average current requirements can be estimated by mutiplying the duty cycle of
the requests by the specified continuous current number.

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.

5.2 RF 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 121 for applications in the 2.4GHz band, and in Figure 5.5 Typical Sub-GHz RF impedance-matching network circuits on page
121 for applications in the sub-GHz band. Application-specific component values can be found in application notes AN923: EFR32 sub-
GHz Matching Guide and AN930: EFR32 2.4 GHz Matching Guide. 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). As an addition resource, application note AN1081: Integrated Passive Devices for EFR32 Sub-GHz RF
Matching provides a list of supported Integrated Passive Devices (IPDs) along with design and layout considerations that can further
simplify the external RF matching network for sub-GHz applications.

Certain alternate function locations may have non-interference priority. These locations will take precedence over any other functions
selected on that pin (i.e. another alternate function enabled to the same pin inadvertently).
Some alternate functions may also have high speed priority on certain locations. These locations ensure the fastest possible paths to
the pins for timing-critical signals.
The following table lists the alternate functions and locations with special priority.

6.8 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 6.6 APORT Connection Diagram on page 173 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 6.6. 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.

Pin Definitions
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.
