EFM32PG1 Data Sheet
System Overview
3.2 Power
The EFM32PG1 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 com-
ponents, supplying up to a total of 200 mA.
3.2.1 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 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.
3.2.2 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. 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 volt-
age 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 avoid dipping the input supply due to excessive current transi-
ents.
3.3 General Purpose Input/Output (GPIO)
EFM32PG1 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.
3.4 Clocking
3.4.1 Clock Management Unit (CMU)
The Clock Management Unit controls oscillators and clocks in the EFM32PG1. Individual enabling and disabling of clocks to all periph-
eral modules is perfomed 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.
3.4.2 Internal and External Oscillators
The EFM32PG1 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 debug 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
3.5 Counters/Timers and PWM
3.5.1 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.
3.5.2 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.
3.5.3 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.
3.5.4 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.
3.5.5 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.
3.5.6 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.
3.6 Communications and Other Digital Peripherals
3.6.1 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
I2S

EFM32PG1 Data Sheet
System Overview
3.6.2 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.
3.6.3 Inter-Integrated Circuit Interface (I2C)
The I2C module provides an interface between the MCU and a serial I2C bus. It is capable of acting as both a master and a slave and
supports multi-master buses. 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 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.
3.6.4 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 can be applied by the PRS. The PRS allows pe-
ripheral to act autonomously without waking the MCU core, saving power.
3.7 Security Features
3.7.1 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. Common 16-bit polynomials are 0x1021 (CCITT-16), and 0x8005 (802.15.4, and USB).
3.7.2 Crypto Accelerator (CRYPTO)
The Crypto Accelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. EFM32PG1 devices
support AES encryption and decryption with 128- or 256-bit keys, ECC over both GF(P) and GF(2m), and SHA-1 and SHA-2 (SHA-224
and SHA-256).
Supported modes of operation for AES include: ECB, CTR, CBC, PCBC, CFB, OFB, 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 module 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 Analog
3.8.1 Analog Port (APORT)
The Analog Port (APORT) is an analog interconnect matrix allowing access to analog modules ADC, ACMP, and IDAC on a flexible
selection of pins. Each APORT bus consists of analog switches connected to a common wire. Since many clients can operate differen-
tially, buses are grouped by X/Y pairs.
3.8.2 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.

EFM32PG1 Data Sheet
System Overview
3.8.3 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 MSamples/s. 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.
3.8.4 Digital to Analog Current Converter (IDAC)
The Digital to Analog Current Converter 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 current is programmable between 0.05 µA and 64 µA with several
ranges with various step sizes.
3.9 Reset Management Unit (RMU)
The RMU is responsible for handling reset of the EFM32PG1. A wide range of reset sources are available, including several power
supply monitors, pin reset, software controlled reset, core lockup reset and watchdog reset.
3.10 Core and Memory
3.10.1 Processor Core
The ARM Cortex-M processor includes a 32-bit RISC processor integrating the following features and tasks in the system:

• Up to 256 KB flash program memory
• Up to 32 KB RAM data memory
• Configuration and event handling of all modules
• 2-pin Serial-Wire debug interface
3.10.2 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.
3.10.3 Linked Direct Memory Access Controller (LDMA)
The Linked Direct Memory Access (LDMA) controller features 8 channels capable of performing memory operations independently of
software. This reduces both energy consumption and software workload. The LDMA allows operations to be linked together and stag-
ed, enabling sophisticated operations to be implemented.
