TOP 10 FEATURES THAT ENABLE

ENERGY EFFICIENT IOT APPLICATIONS

Do you want to…

… create an energy harvesting enabled wireless switch application

… a wireless fitness tracker application

… a smart water meter application

…. or a GPS avalanche monitor application?

Now you can,

with EFM32 Gecko microcontrollers!

Let’s take a look at the 10 factors that help you create these cool applications

#1. VERY LOW ACTIVE POWER CONSUMPTION

• The energy friendly EFM32 microcontrollers have been designed to significantly reduce active mode power consumption.

• At 32 MHz and 3 V the MCU only consumes 150μA/MHz while running real life code.

#2. PROCESSING TIME

• The EFM32 microcontroller family is built around the 32-bit ARM Cortex-M processor core.

• The Cortex-M is much more processing efficient than 8- and 16-bit CPUs. Tasks are executed with fewer clock cycles, reducing the active period.

#3. VERY FAST WAKE UP TIME

• EFM32 MCUs minimize the inefficient wake-up period between deep sleep and active mode.

• EFM32 microcontrollers have reduced the wake-up time to 2 μs, ensuring as little energy as possible is used before the CPU starts processing its tasks.

#4. ULTRA-LOW STANDBY

• The EFM32 combines ultra-low power technology with clever power management to reduce energy usage in standby modes while still performing basic operations.

#5. AUTONOMOUS PERIPHERAL OPERATION

• The EFM32 peripherals can operate in low energy modes without using the CPU.

• By using autonomous peripherals, an application can reduce power consumption while performing complex tasks.

#6. PRS – PERIPHERAL REFLEX SYSTEM

• This system makes it possible to directly connect one peripheral to another without involving the CPU.

• This allows peripherals to produce signals which other peripherals are able to consume then react to while the CPU remains asleep.

#7. WELL ARCHITECTED ENERGY MODES

• EFM32 microcontrollers have 5 efficient energy modes which give designers the flexibility to optimize their application for highest performance and longest battery life.

#8. ENERGY EFFICIENT PERIPHERALS

• EFM32 microcontrollers are packed with peripherals designed for low energy operation, which increase battery life 4 times compared to other low power solutions. 

#9. LESENSE – LOW ENERGY SENSOR INTERFACE• LESENSE provides a configurable and energy efficient way of

controlling 16 or more external analog sensors without involving the Cortex CPU.

• LESENSE works in the 900 nA deep sleep mode and enables autonomous monitoring of virtually any type of analog sensor control scheme.
