...the world's most energy friendly microcontrollers 2015-03-06 - efm32tg110fxx - d0013_rev1.40 4 www.silabs.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 efm32tg. 2.1.6 energy management unit (emu) the energy management unit (emu) manage all the low energy modes (em) in efm32tg 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 efm32tg. 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 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.
...the world's most energy friendly microcontrollers 2015-03-06 - efm32tg110fxx - d0013_rev1.40 5 www.silabs.com 2.1.11 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, irda and i2s devices. 2.1.12 pre-programmed uart 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. 2.1.13 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. 2.1.14 timer/counter (timer) the 16-bit general purpose timer has 3 compare/capture channels for input capture and compare/pulse- width modulation (pwm) output. 2.1.15 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. 2.1.16 low energy timer (letimer) the unique letimer tm , the low energy timer, is a 16-bit timer that is available in energy mode em2 in addition to em1 and em0. because of this, it can 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 waveforms with minimal software intervention. it is also connected to the real time counter (rtc), and can be configured to start counting on compare matches from the rtc. 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 indi- cating 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.
...the world's most energy friendly microcontrollers 2015-03-06 - efm32tg110fxx - d0013_rev1.40 6 www.silabs.com 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. 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 2 external pins and 6 internal signals. 2.1.21 digital to analog converter (dac) the digital to analog converter (dac) can convert a digital value to an analog output voltage. the dac is fully differential rail-to-rail, with 12-bit resolution. it has one single ended output buffer connected to channel 0. the dac may be used for a number of different applications such as sensor interfaces or sound output. 2.1.22 operational amplifier (opamp) the efm32tg110 features 3 operational amplifiers. the operational amplifier is a versatile general purpose amplifier with rail-to-rail differential input and rail-to-rail single ended output. the input can be set to pin, dac or opamp, whereas the output can be pin, opamp or adc. the current is programmable and the opamp has various internal configurations such as unity gain, programmable gain using internal resistors etc. 2.1.23 low energy sensor interface (lesense) the low energy sensor interface (lesense tm ), is a highly configurable sensor interface with support for up to 4 individually configurable sensors. by controlling the analog comparators and dac, lesense is capable of supporting a wide range of sensors and measurement schemes, and can for instance mea- sure lc sensors, resistive sensors and capacitive sensors. lesense also includes a programmable fsm which enables simple processing of measurement results without cpu intervention. lesense is available in energy mode em2, in addition to em0 and em1, making it ideal for sensor monitoring in applications with a strict energy budget. 2.1.24 advanced encryption standard accelerator (aes) the aes accelerator performs aes encryption and decryption with 128-bit or 256-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. 2.1.25 general purpose input/output (gpio) in the efm32tg110, there are 17 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 11 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.
