Rev. 1.0 | 11 EFM32GG12 Family Data Sheet System Overview 3.2 Power The EFM32GG12 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. A 5 V regulator is available on some OPNs, allowing the device to be powered directly from 5 V power sources, such as USB. 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. The EFM32GG12 device family includes support for internal supply voltage scaling, as well as two different power domain groups for peripherals. These enhancements allow for further supply current reductions and lower overall power consumption. AVDD and VREGVDD need to be 1.8 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 components, 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 voltage 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 prevent input supply voltage droops due to excessive output current transients. 3.2.3 5 V Regulator A 5 V input regulator is available, allowing the device to be powered directly from 5 V power sources such as the USB VBUS line. The regulator is available in all energy modes, and outputs 3.3 V to be used to power the USB PHY and other 3.3 V systems. Two inputs to the regulator allow for seamless switching between local and external power sources. silabs.com | Building a more connected world. Rev. 1.0 | 12 EFM32GG12 Family Data Sheet System Overview 3.2.4 EM2 and EM3 Power Domains The EFM32GG12 has three independent peripheral power domains for use in EM2 and EM3. Two of these domains are dynamic and can be shut down to save energy. Peripherals associated with the two dynamic power domains are listed in Table 3.1 EM2 and EM3 Peripheral Power Subdomains on page 13. If all of the peripherals in a peripheral power domain are unused, the power domain for that group will be powered off in EM2 and EM3, reducing the overall current consumption of the device. Other EM2, EM3, and EM4capable peripherals and functions not listed in the table below reside on the primary power domain, which is always on in EM2 and EM3. Table 3.1. EM2 and EM3 Peripheral Power Subdomains Peripheral Power Domain 1 Peripheral Power Domain 2 ACMP0 ACMP1 PCNT0 PCNT1 ADC0 PCNT2 LETIMER0 CSEN LESENSE VDAC0 APORT LEUART0 - LEUART1 - LETIMER1 - I2C0 - I2C1 - IDAC - ADC1 - ACMP2 - LCD - RTC 3.3 General Purpose Input/Output (GPIO) EFM32GG12 has up to 95 General Purpose Input/Output pins. GPIO are organized on three independent supply rails, allowing for interface to multiple logic levels in the system simultaneously. 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 several 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 EFM32GG12. Individual enabling and disabling of clocks to all peripherals is performed 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. silabs.com | Building a more connected world. Rev. 1.0 | 13 EFM32GG12 Family Data Sheet System Overview 3.4.2 Internal and External Oscillators The EFM32GG12 supports two crystal oscillators and fully integrates five RC oscillators, listed below. • A high frequency crystal oscillator (HFXO) with integrated load capacitors, tunable in small steps, provides a precise timing reference for the MCU. Crystal frequencies in the range from 4 to 50 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. The HFRCO employs fast startup at minimal energy consumption combined with a wide frequency range. When crystal accuracy is not required, it can be operated in free-running mode at a number of factory-calibrated frequencies. A digital phase-locked loop (DPLL) feature allows the HFRCO to achieve higher accuracy and stability by referencing other available clock sources such as LFXO and HFXO. • An integrated auxilliary high frequency RC oscillator (AUXHFRCO) is available for timing the general-purpose ADC and the Serial Wire Viewer port with a wide frequency range. • An integrated universal high frequency RC oscillator (USHFRCO) is available for timing the USB, SDIO and QSPI peripherals. The USHFRCO can be syncronized to the host's USB clock to allow the USB to operate in device mode without the additional cost of an external crystal. • An integrated low frequency 32.768 kHz RC oscillator (LFRCO) can be used as a timing reference in low energy modes, when crystal 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 consumption in low energy modes. 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 Wide Timer/Counter (WTIMER) WTIMER peripherals function just as TIMER peripherals, but are 32 bits wide. They keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the PRS system. The core of each WTIMER is a 32-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 WTIMER 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 WTIMER_0 only. 3.5.3 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 oscillators with the exception of the AUXHFRCO, and it is capable of providing system wake-up at user defined instances. The RTCC includes 128 bytes of general purpose data retention, allowing easy and convenient data storage in all energy modes down to EM4H. 3.5.4 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 waveforms with minimal software intervention.

Specified configuration for Unit gain buffer configuration is: INCBW = 0, HCMDIS = 0, RESINSEL = DISABLE. VINPUT = 0.5 V, VOUTPUT = 0.5 V. 2. Specified configuration for 3X-Gain configuration is: INCBW = 1, HCMDIS = 1, RESINSEL = VSS, VINPUT = 0.5 V, VOUTPUT = 1.5 V. Nominal voltage gain is 3. 3. If the maximum CLOAD is exceeded, an isolation resistor is required for stability. See AN0038 for more information. 4. Current into the load resistor is excluded. When the OPAMP is connected with closed-loop gain > 1, there will be extra current to drive the resistor feedback network. The internal resistor feedback network has total resistance of 143.5 kOhm, which will cause another ~10 µA current when the OPAMP drives 1.5 V between output and ground. 5. In unit gain connection, UGF is the gain-bandwidth product of the OPAMP. In 3x Gain connection, UGF is the gain-bandwidth product of the OPAMP and 1/3 attenuation of the feedback network. 6. Step between 0.2V and VOPA-0.2V, 10%-90% rising/falling range. 7. When INCBW is set to 1 the OPAMP bandwidth is increased. This is allowed only when the non-inverting close-loop gain is ≥ 3, or the OPAMP may not be stable. 8. From enable to output settled. In sample-and-off mode, RC network after OPAMP will contribute extra delay. Settling error < 1mV. 9. When HCMDIS=1 and input common mode transitions the region from VOPA-1.4V to VOPA-1V, input offset will change.

These locations will take precedence over any other functions selected on that pin (i.e. another alternate function enabled to the same pin inadvertently). Some alternate functions may also have high speed priority on certain locations. These locations ensure the fastest possible paths to the pins for timing-critical signals.
