Product details
Overview
EFM32G890F64G-E-BGA112R from Silicon Labs is a 32-bit ARM Cortex-M3 microcontroller optimized for ultra-low-power battery-operated systems. It delivers 32 MHz operation, 64 kB Flash, 16 kB RAM, hardware AES-128/256 acceleration, and energy modes down to 0.6 μA in Stop (EM3) with RAM retention - enabling multi-year operation in smart metering and wearable health devices.
For engineers reviewing the EFM32G890F64G-E-BGA112R datasheet, EFM32G890F64G-E-BGA112R pinout, EFM32G890F64G-E-BGA112R application, or EFM32G890F64G-E-BGA112R equivalent, key selection factors include verified BGA112 package compatibility, confirmed 1.98–3.8 V supply range, validated EM2/EM3 wake-up timing, and documented PRS-based autonomous peripheral coordination without CPU intervention.
Technical Context
The EFM32G890F64G-E-BGA112R implements an ARM Cortex-M3 core with Memory Protection Unit (MPU), Wake-up Interrupt Controller, and SysTick timer. Its Energy Management Unit (EMU) supports five distinct energy modes (EM0–EM4), with EM2 (Deep Sleep) retaining RTC and PRS operation at 0.9 μA and EM3 (Stop) maintaining RAM/CPU state at 0.6 μA while enabling wake-up via external interrupts or analog comparators.
Clock management uses dual-oscillator architecture: HFXO (up to 32 MHz) for active mode and LFXO (32.768 kHz) for low-energy peripherals. The Peripheral Reflex System (PRS) enables direct hardware-level signaling between peripherals - e.g., ADC completion triggering DMA transfer or TIMER compare event starting DAC conversion - eliminating CPU polling and reducing active time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 @ 32 MHz - delivers 1.25 Dhrystone MIPS/MHz with MPU for memory isolation in safety-critical firmware. |
