preliminary ...the world's most energy friendly microcontrollers 2012-09-11 - EFM32GG980fxx - d0045_rev1.00 4 www.energymicro.com 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. 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 dma controller licensed from arm. 2.1.5 reset management unit (rmu) the rmu is responsible for handling the reset functionality of the efm32gg. 2.1.6 energy management unit (emu) the energy management unit (emu) manage all the low energy modes (em) in efm32gg microcon- trollers. 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 efm32gg. 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 appli- cation 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 external bus interface (ebi) the external bus interface provides access to external parallel interface devices such as sram, flash, adcs and lcds. the interface is memory mapped into the address bus of the cortex-m3. this enables seamless access from software without manually manipulating the io settings each time a read or write is performed. the data and address lines are multiplexed in order to reduce the number of pins required to interface the external devices. the timing is adjustable to meet specifications of the external devices. the interface is limited to asynchronous devices. 2.1.11 tft direct drive the ebi contains a tft controller which can drive a tft via a 565 rgb interface. the tft controller supports programmable display and port sizes and offers accurate control of frequency and setup and
preliminary ...the world's most energy friendly microcontrollers 2012-09-11 - EFM32GG980fxx - d0045_rev1.00 5 www.energymicro.com hold timing. direct drive is supported for tft displays which do not have their own frame buffer. in that case tft direct drive can transfer data from either on-chip memory or from an external memory device to the tft at low cpu load. automatic alpha-blending and masking is also supported for transfers through the ebi interface. 2.1.12 universal serial bus controller (usb) the usb is a full-speed usb 2.0 compliant otg host/device controller. the usb can be used in device, on-the-go (otg) dual role device or host-only configuration. in otg mode the usb supports both host negotiation protocol (hnp) and session request protocol (srp). the device supports both full- speed (12mbit/s) and low speed (1.5mbit/s) operation. the usb device includes an internal dedicated descriptor-based scatter/garther dma and supports up to 6 out endpoints and 6 in endpoints, in addition to endpoint 0. the on-chip phy includes all otg features, except for the voltage booster for supplying 5v to vbus when operating as host. 2.1.13 inter-integrated circuit interface (i2c) the i 2 c module provides an interface between the mcu and a serial i 2 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 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 i 2 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. 2.1.14 universal synchronous/asynchronous receiver/transmitter (us- art) 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 , i2s devices and irda devices. 2.1.15 pre-programmed serial bootloader the bootloader presented in application note an0003 is pre-programmed in the device at factory. auto- baud and destructive write are supported. the autobaud feature, interface and commands are described further in the application note. 2.1.16 universal asynchronous receiver/transmitter (uart) the universal asynchronous serial receiver and transmitter (uart) is a very flexible serial i/o module. it supports full- and half-duplex asynchronous uart communication. 2.1.17 low energy universal asynchronous receiver/transmitter (leuart) the unique leuart tm , 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. 2.1.18 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.
