System Overview 3.1 Introduction The EZR32HG320 Wireless MCUs are the latest in the Silicon Labs family of wireless MCUs delivering a high-performance, low-energy wireless solution integrated into a small form factor package. By combining a high performance sub-GHz RF transceiver with an energy efficient 32-bit ARM Cortex-M0+, the EZR32HG family provides designers with the ultimate in flexibility with a family of pin-compatible parts that scale from 32 to 64 kB of flash and support Silicon Labs EZRadio or EZRadioPRO transceivers. The ultra-low power operating modes and fast wake-up times combined with the low transmit and receive power consumption of the sub-GHz radio result in a solution optimized for low power and battery powered applications. For a complete feature set and in-depth information on the modules, refer to the EZR32HG Reference Manual. The EZR32HG320 block diagram is shown below.

Block Diagram 3.1.1 ARM Cortex-M0+ Core The ARM Cortex-M0+ includes a 32-bit RISC processor which can achieve as much as 0.9 Dhrystone MIPS/MHz. A Wake-up Interrupt Controller handling interrupts triggered while the CPU is asleep is included as well. The EZR32 implementation of the Cortex-M0+ is described in detail in ARM Cortex-M0+ Devices Generic User Guide. 3.1.2 Debugging Interface (DBG) These devices include hardware debug support through a 2-pin serial-wire debug interface. 3.1.3 Memory System Controller (MSC) The Memory System Controller (MSC) is the program memory unit of the EZR32HG 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. 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. silabs.com | Building a more connected world. Rev. 1.2 | 7 EZR32HG320 Data Sheet System Overview 3.1.4 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. 3.1.5 Reset Management Unit (RMU) The Reset Management Unit (RMU) is responsible for handling the reset functionality of the EZR32HG. 3.1.6 Energy Management Unit (EMU) The Energy Management Unit (EMU) manages all the low energy modes (EM) in EZR32HG 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. 3.1.7 Clock Management Unit (CMU) The Clock Management Unit (CMU) is responsible for controlling the oscillators and clocks on-board the EZR32HG. 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. 3.1.8 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, for example, be caused by an external event, such as an ESD pulse, or by a software failure. 3.1.9 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. 3.1.10 Universal Serial Bus Controller (USB) The USB is a full-speed USB 2.0 compliant device controller. The device supports both fullspeed (12 MBit/s) and low speed (1.5 MBit/s) operation. The USB also supports a Low Energy Mode that can be used to lower the current consumption up to 90% by shutting off the clock to the USB Core adn possibly suspending the USHFRCO. The USB device includes an internal dedicated Descriptor-Based Scatter/Garther DMA and supports up to 3 OUT endpoints and 3 IN endpoints, in addition to endpoint 0. 3.1.11 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. Both standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates all the way from 10 kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also provided to allow implementation of an SMBus compliant system. The interface provided to software by the I2C 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. 3.1.12 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. 3.1.13 Pre-Programmed USB/UART Bootloader The bootloader presented in application note AN0042 is pre-programmed in the device at the factory. The bootloader enables users to program the EZR32 through a UART or a USB CDC class virtual UART without the need for a debuger. The autobaud feature, interface, and commands are described further in the application note. silabs.com | Building a more connected world. Rev. 1.2 | 8 EZR32HG320 Data Sheet System Overview 3.1.14 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART) The unique Low Energy Universal Asynchronous Receiver/Transmitter (LEUART™), the Low Energy UART, is a UART that allows twoway 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. 3.1.15 Timer/Counter (TIMER) The 16-bit general purpose Timer has 3 compare/capture channels for input capture and compare/Pulse-Width Modulation (PWM) output. TIMER0 also includes a Dead-Time Insertion module suitable for motor control applications. 3.1.16 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. 3.1.17 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. 3.1.18 Voltage Comparator (VCMP) The Voltage Supply Comparator (VCMP) 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. 3.1.19 Analog to Digital Converter (ADC) The Analog to Digital Converter (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 4 external pins and 6 internal signals. 3.1.20 Current Digital to Analog Converter (IDAC) The current digital to analog converter (IDAC) 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. 3.1.21 Advanced Encryption Standard Accelerator (AES) The Advanced Encryption Standard Accelerator (AES) performs AES encryption and decryption with 128-bit keys. Encrypting or decrypting one 128-bit data block takes 52 HFCORECLK cycles with 128-bit keys and 75 HFCORECLK cycles with 256-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). 3.1.22 General Purpose Input/Output (GPIO) In the EZR32HG320, there are 25 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 16 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. silabs.com | Building a more connected world. Rev. 1.2 | 9 EZR32HG320 Data Sheet System Overview 3.1.23 EZRadio® and EZRadioPro® Transceivers The EZR32HG family of devices is built using high-performance, low-current EZRadio and EZRadioPro RF transceivers covering the sub-GHz frequency bands from 142 to 1050 MHz. These devices offer outstanding sensitivity of up to –133 dBm (using EZRadioPro) while achieving extremely low active and standby current consumption. The EZR32HG devices using the EZRadioPro transceiver offer frequency coverage in all major bands and include optimal phase noise, blocking, and selectivity performance for narrow band and licensed band applications, such as FCC Part 90 and 169 MHz wireless Mbus. The 69 dB adjacent channel selectivity with 12.5 kHz channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrow band operation. The active mode TX current consumption of 18 mA at +10 dBm and RX current of 10 mA coupled with extremely low standby current and fast wake times is optimized for extended battery life in the most demanding applications. The EZR32HG devices can achieve up to +27 dBm output power with built-in ramping control of a low-cost external FET. The devices can meet worldwide regulatory standards: FCC, ETSI, and ARIB. All devices using the EZRadioPRO tranceiver are designed to be compliant with 802.15.4g and WMbus smart metering standards. The devices are highly flexible and can be programmed and configured via Simplicity Studio, available at www.silabs.com. Communications between the radio and MCU are done over USART and IRQ, which requires the pins to be configured in the following way: Table 3.1.
