With a unique combination of the powerful 32-bit ARM Cortex-M0+, innovative low energy techniques, short wake-up time from energy saving modes, and a wide selection of peripherals, the EFM32HG microcontroller is well suited for any battery operated application as well as other systems requiring high performance and low-energy consumption. This section gives a short introduction to each of the modules in general terms and also shows a summary of the configuration for the EFM32HG350 devices. For a complete feature set and in-depth information on the modules, the reader is referred to the EFM32HG Reference Manual. A block diagram of the EFM32HG350 is shown in Figure 2.1 (p. 3) .

A Wake-up Interrupt Controller handling interrupts triggered while the CPU is asleep is included as well. The EFM32 implementation of the Cortex-M0+ is described in detail in ARM Cortex-M0+ Devices Generic User Guide. 2.1.2 Debug Interface (DBG) This device includes hardware debug support through a 2-pin serial-wire debug interface and a Micro Trace Buffer (MTB) for data/instruction tracing. 2.1.3 Memory System Controller (MSC) The Memory System Controller (MSC) is the program memory unit of the EFM32HG microcontroller. The flash memory is readable and writable from both the Cortex-M0+ 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. Additionally, the information block is available for special user data and flash lock bits. 2015-05-06 - EFM32HG350FXX - _Rev0.91 3 www.silabs.com Preliminary ...the world's most energy friendly microcontrollers There is also a read-only page in the information block containing system and device calibration data. Read and write operations are supported in the energy modes EM0 and EM1. 2.1.4 Direct Memory Access Controller (DMA) The Direct Memory Access (DMA) controller performs memory operations independently of the CPU. This has the benefit of reducing the energy consumption and the workload of the CPU, and enables the system to stay in low energy modes when moving for instance data from the USART to RAM or from the External Bus Interface to a PWM-generating timer. The DMA controller uses the PL230 µDMA controller licensed from ARM. 2.1.5 Reset Management Unit (RMU) The RMU is responsible for handling the reset functionality of the EFM32HG. 2.1.6 Energy Management Unit (EMU) The Energy Management Unit (EMU) manage all the low energy modes (EM) in EFM32HG microcontrollers. Each energy mode manages if the CPU and the various peripherals are available. The EMU can also be used to turn off the power to unused SRAM blocks. 2.1.7 Clock Management Unit (CMU) The Clock Management Unit (CMU) is responsible for controlling the oscillators and clocks on-board the EFM32HG. The CMU provides the capability to turn on and off the clock on an individual basis to all peripheral modules in addition to enable/disable and configure the available oscillators. The high degree of flexibility enables software to minimize energy consumption in any specific application by not wasting power on peripherals and oscillators that are inactive. 2.1.8 Watchdog (WDOG) The purpose of the watchdog timer is to generate a reset in case of a system failure, to increase application reliability. The failure may e.g. be caused by an external event, such as an ESD pulse, or by a software failure. 2.1.9 Peripheral Reflex System (PRS) The Peripheral Reflex System (PRS) system is a network which lets the different peripheral module communicate directly with each other without involving the CPU. Peripheral modules which send out Reflex signals are called producers. The PRS routes these reflex signals to consumer peripherals which apply actions depending on the data received. The format for the Reflex signals is not given, but edge triggers and other functionality can be applied by the PRS. 2.1.10 Low Energy USB The unique Low Energy USB peripheral provides a full-speed USB 2.0 compliant device controller and PHY with ultra-low current consumption. The device supports both full-speed (12MBit/s) and low speed (1.5MBit/s) operation, and includes a dedicated USB oscillator with clock recovery mechanism for crystal-free operation. No external components are required. The Low Energy Mode ensures the current consumption is optimized and enables USB communication on a strict power budget. The USB device includes an internal dedicated descriptor-based Scatter/Gather DMA and supports up to 3 OUT endpoints and 3 IN endpoints, in addition to endpoint 0. The on-chip PHY includes software controllable pull-up and pull-down resistors. 2.1.11 Inter-Integrated Circuit Interface (I2C) 2 2 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. Both standard-mode, fast-mode and fastmode plus speeds are supported, allowing transmission rates all the way from 10 kbit/s up to 1 Mbit/s. 2015-05-06 - EFM32HG350FXX - _Rev0.91 4 www.silabs.com Preliminary ...the world's most energy friendly microcontrollers Slave arbitration and timeouts are also provided to allow implementation of an SMBus compliant system. 2 The interface provided to software by the I C module, allows both fine-grained control of the transmission process and close to automatic transfers. Automatic recognition of slave addresses is provided in all energy modes. 2.1.12 Universal Synchronous/Asynchronous Receiver/Transmitter (USART) The Universal Synchronous Asynchronous serial Receiver and Transmitter (USART) is a very flexible serial I/O module. It supports full duplex asynchronous UART communication as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with ISO7816 SmartCards, IrDA and I2S devices. 2.1.13 Pre-Programmed USB/UART Bootloader The bootloader presented in application note AN0042 is pre-programmed in the device at factory. The bootloader enables users to program the EFM32 through a UART or a USB CDC class virtual UART without the need for a debugger. The autobaud feature, interface and commands are described further in the application note. 2.1.14 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART) TM The unique LEUART , the Low Energy UART, is a UART that allows 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/ s. The LEUART includes all necessary hardware support to make asynchronous serial communication possible with minimum of software intervention and energy consumption. 2.1.15 Timer/Counter (TIMER) The 16-bit general purpose Timer has 3 compare/capture channels for input capture and compare/PulseWidth Modulation (PWM) output. TIMER0 also includes a Dead-Time Insertion module suitable for motor control applications. 2.1.16 Real Time Counter (RTC) The Real Time Counter (RTC) contains a 24-bit counter and is clocked either by a 32.768 kHz crystal oscillator, or a 32.768 kHz RC oscillator. In addition to energy modes EM0 and EM1, the RTC is also available in EM2. This makes it ideal for keeping track of time since the RTC is enabled in EM2 where most of the device is powered down. 2.1.17 Pulse Counter (PCNT) The Pulse Counter (PCNT) can be used for counting pulses on a single input or to decode quadrature encoded inputs. It runs off either the internal LFACLK or the PCNTn_S0IN pin as external clock source. The module may operate in energy mode EM0 - EM3. 2.1.18 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 higher. Inputs can either be one of the selectable internal references or from external pins. Response time and thereby also the current consumption can be configured by altering the current supply to the comparator. 2.1.19 Voltage Comparator (VCMP) The Voltage Supply Comparator is used to monitor the supply voltage from software. An interrupt can be generated when the supply falls below or rises above a programmable threshold. Response time and thereby also the current consumption can be configured by altering the current supply to the comparator. 2015-05-06 - EFM32HG350FXX - _Rev0.91 5 www.silabs.com Preliminary ...the world's most energy friendly microcontrollers 2.1.20 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 one million samples per second. The integrated input mux can select inputs from 3 external pins and 6 internal signals. 2.1.21 Current Digital to Analog Converter (IDAC) The current digital to analog converter can source or sink a configurable constant current, which can be output on, or sinked from pin or ADC. The current is configurable with several ranges of various step sizes. 2.1.22 Advanced Encryption Standard Accelerator (AES) The AES accelerator performs AES encryption and decryption with 128-bit. Encrypting or decrypting one 128-bit data block takes 52 HFCORECLK cycles with 128-bit keys. The AES module is an AHB slave which enables efficient access to the data and key registers. All write accesses to the AES module must be 32-bit operations, i.e. 8- or 16-bit operations are not supported. 2.1.23 General Purpose Input/Output (GPIO) In the EFM32HG350, there are 22 General Purpose Input/Output (GPIO) pins, which are divided into ports with up to 16 pins each. These pins can individually be configured as either an output or input. More advanced configurations like open-drain, filtering and drive strength can also be configured individually for the pins. The GPIO pins can also be overridden by peripheral pin connections, like Timer PWM outputs or USART communication, which can be routed to several locations on the device. The GPIO supports up to 10 asynchronous external pin interrupts, which enables interrupts from any pin on the device. Also, the input value of a pin can be routed through the Peripheral Reflex System to other peripherals. 2.2 Configuration Summary The features of the EFM32HG350 is a subset of the feature set described in the EFM32HG Reference Manual.
