Product details
Overview
EFM32G880F32G-E-QFP100R from Silicon Labs is a 32-bit ARM Cortex-M3 microcontroller optimized for ultra-low-power battery-operated systems, featuring 32 kB Flash, 8 kB RAM, 0.6 μA Stop mode current, 180 μA/MHz Run mode consumption, and hardware AES-128 encryption. It serves as the main system controller in smart metering, health wearables, and industrial sensor nodes requiring long runtime and secure firmware updates.
For engineers reviewing the EFM32G880F32G-E-QFP100R datasheet, EFM32G880F32G-E-QFP100R pinout, EFM32G880F32G-E-QFP100R application, or EFM32G880F32G-E-QFP100R equivalent, this page delivers verified electrical specs, LQFP100 package mapping, energy mode behavior, peripheral reflex system configuration, and validated alternative MCUs for low-energy embedded design.
Technical Context
The EFM32G880F32G-E-QFP100R implements the ARM Cortex-M3 core at up to 32 MHz with Memory Protection Unit (MPU), Wake-up Interrupt Controller, and SysTick timer. Its Energy Management Unit (EMU) supports five energy modes-EM0 (Active) to EM4 (Shutoff)-with autonomous peripheral operation down to EM2 (Deep Sleep) and EM3 (Stop) while retaining RAM and CPU state.
Clock management includes dual oscillators: high-frequency crystal (HFXO) up to 32 MHz and low-frequency crystal (LFXO) at 32.768 kHz for RTC/LEUART timing. The Peripheral Reflex System (PRS) enables CPU-free inter-peripheral signaling between TIMER, RTC, LEUART, and ADC, reducing wake-up latency and active time.
Key Specifications

FAQ
What is the maximum operating frequency of the EFM32G880F32G-E-QFP100R?
The EFM32G880F32G-E-QFP100R operates at up to 32 MHz using its high-frequency crystal oscillator (HFXO) or internal HFRCO. This frequency is fully supported across all specified temperature and voltage ranges (−40 °C to +85 °C, 1.98–3.8 V), and enables deterministic real-time execution of sensor fusion and communication stacks. The EFM32G880F32G-E-QFP100R achieves 1.25 DMIPS/MHz at this speed.
Does the EFM32G880F32G-E-QFP100R support hardware encryption?
Yes, the EFM32G880F32G-E-QFP100R integrates a dedicated hardware AES-128 accelerator that completes encryption in 54 clock cycles with zero CPU involvement. It supports ECB and CTR modes, and key storage is protected by lock bits in the information flash page. This capability is confirmed in the EFM32G Data Sheet Rev. 2.20 Section 3.1.24 and enables secure firmware updates and data-at-rest protection in the EFM32G880F32G-E-QFP100R.
What energy modes are available on the EFM32G880F32G-E-QFP100R, and which peripherals remain active in each?
The EFM32G880F32G-E-QFP100R supports five energy modes: EM0 (Active), EM1 (Sleep), EM2 (Deep Sleep), EM3 (Stop), and EM4 (Shutoff). In EM2, RTC, LEUART, and PRS remain functional; in EM3, only RAM, CPU state, brown-out detector, and POR are retained at 0.6 μA. EM4 disables all clocks and regulators except for pin-reset detection. These modes and their peripheral availability are fully documented in Section 4.4 of the EFM32G Data Sheet for the EFM32G880F32G-E-QFP100R.
Can the EFM32G880F32G-E-QFP100R drive an LCD directly?
Yes, the EFM32G880F32G-E-QFP100R includes an integrated LCD controller supporting up to 4×40 segment displays with on-chip voltage boost, adjustable contrast, and autonomous animation sequencing. It requires no external bias generator or frame controller, reducing BOM count and PCB area. This feature is explicitly listed in the Feature List (Rev. 2.20 p.2) and detailed in Section 3.1.26 of the EFM32G Data Sheet for the EFM32G880F32G-E-QFP100R.
Is the EFM32G880F32G-E-QFP100R pin-compatible with other EFM32G LQFP100 variants?
Yes, all EFM32G devices in the LQFP100 package-including EFM32G280F32G-E-QFP100, EFM32G280F64G-E-QFP100, EFM32G280F128G-E-QFP100, and EFM32G880F32G-E-QFP100R-share identical pinouts and mechanical footprint. Differences are limited to Flash/RAM size, maximum frequency, and peripheral enablement (e.g., EBI presence), not pin assignment. This is confirmed in Table 2.1 and Section 5.9.1 (Pinout) of the EFM32G Data Sheet for the EFM32G880F32G-E-QFP100R.
