gecko bluetooth ? smart soc family data sheet system overview silabs.com | building a more connected world. rev. 1.1 | 4 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). 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 improve link budget for 802.15.4 dsss-oqpsk phy configuration in the 2.4ghz band, using complementary control outputs to an external switch. internal configurable hardware controls automatic switching between antennae during rf receive detection operations. 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. 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. efr32bg1 blue gecko bluetooth ? smart soc family data sheet system overview silabs.com | building a more connected world. rev. 1.1 | 5 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. 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 efr32bg1 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 efr32bg1 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. 3.2.10 radio controller (rac) the radio controller controls the top level state of the radio subsystem in the efr32bg1. 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 efr32bg1 blue gecko bluetooth ? smart soc family data sheet system overview silabs.com | building a more connected world. rev. 1.1 | 6 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. efr32bg1 blue gecko bluetooth ? smart soc family data sheet system overview silabs.com | building a more connected world. rev. 1.1

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 multiple 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. .. - onverter the - buck converter covers a wide range of load currents and provides up to efficiency in energy modes em, em, em and em, and can supply up to ma to the device and surrounding components. atented r noise mitigation allows operation of the - converter without degrading sensitivity of radio components. rotection features include programmable current limiting, short-circuit protection, and dead-time protection. the - converter may also enter bypass mode when the input voltage is too low for efficient operation. in bypass mode, the - input supply is internally connected directly to its output through a low resistance switch. ypass mode also supports in-rush current limiting to prevent input supply voltage droops due to ecessive output current tran- sients. . eneral urpose inputoutput (io) er has up to eneral urpose inputoutput pins. each io 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 io pin. the io pins can be overridden by peripheral connections, like i communication. each peripheral connection can be routed to sev- eral io pins on the device. the input value of a io pin can be routed through the eripheral refle ystem to other peripherals. the io subsystem supports asynchronous eternal pin interrupts. . locking .. lock management unit (mu) the lock management unit controls oscillators and clocks in the er. individual enabling and disabling of clocks to all periph- eral modules is performed by the mu. the mu also controls enabling and configuration of the oscillators. a high degree of fleibility allows software to optimie energy consumption in any specific application by minimiing power dissipation in unused peripherals and oscillators. .. internal and eternal oscillators the er supports two crystal oscillators and fully integrates four r oscillators, listed below. a high freuency crystal oscillator (o) with integrated load capacitors, tunable in small steps, provides a precise timing refer- ence for the mu. rystal freuencies in the range from to m are supported. an eternal clock source such as a to can also be applied to the o input for improved accuracy over temperature. a . k crystal oscillator (o) provides an accurate timing reference for low energy modes. an integrated high freuency r oscillator (ro) is available for the mu system, when crystal accuracy is not reuired. the ro employs fast startup at minimal energy consumption combined with a wide freuency range. an integrated auilliary high freuency r oscillator (auro) is available for timing the general-purpose a and the erial ire debug port with a wide freuency range. an integrated low freuency . k r oscillator (ro) can be used as a timing reference in low energy modes, when crys- tal accuracy is not reuired. an integrated ultra-low freuency k r oscillator (uro) is available to provide a timing reference at the lowest energy con- sumption in low energy modes. er lue ecko luetooth mart o amily ata heet ystem overview silabs.com uilding a more connected world. rev. . 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. 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 ? i 2 s efr32bg1 blue gecko bluetooth ? smart soc family data sheet system overview silabs.com |

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 can be applied by the prs. the prs allows pe- ripheral to act autonomously without waking the mcu core, saving power. . security eatures .. pcrc eneral purpose cyclic redundancy check the pcrc module implements a cyclic redundancy check crc function. t supports both -bit and -bit polynomials. the sup- ported -bit polynomial is xc eee ., while the -bit polynomial can be programmed to any value, depending on the needs of the application. .. crypto ccelerator crpt the crypto ccelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. er devices sup- port es encryption and decryption with - or -bit keys, ecc over both p and m , s- and s- s- and s-. supported block cipher modes of operation for es include ec, ctr, cc, pcc, c, , cm, cc-mc, mc and ccm. supported ecc st recommended curves include p-, p-, p-, -, -, - and -. the crpt is tightly linked to the radio uffer controller uc enabling fast and efficient autonomous cipher operations on data buffer content. t allows fast processing of cm es, ecc and s with little cpu intervention. crpt also provides trigger sig- nals for m read and write operations. . nalog .. nalog port prt the nalog port prt is an analog interconnect matrix allowing access to many analog modules on a flexible selection of pins. each prt bus consists of analog switches connected to a common wire. since many clients can operate differentially, buses are grouped by pairs. .. nalog comparator cmp the nalog comparator is used to compare the voltage of two analog inputs, with a digital output indicating which input voltage is high- er. nputs are selected from among internal references and external pins. the tradeoff between response time and current consumption is configurable by software. two -bit reference dividers allow for a wide range of internally-programmable reference sources. the cmp can also be used to monitor the supply voltage. n interrupt can be generated when the supply falls below or rises above the programmable threshold.

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. a complete description of aport functionality can be found in the reference manual. 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. efr32bg1 blue gecko
