2. EFM32 increases battery life by reducing the total energy consumption
1. Very low active power consumption 6. PRS - Peripheral Reflex System Cortex CPU
EFM32 only uses 160 µA/MHz Predictable and fast signalling
with a 3 volts power supply while between peripherals without TIMER ADC
running application code any CPU intervention
7. Well architected Energy Modes
2. Reduced processing time Optimize your application with 0123 4
The low power, high performance 5 flexible Energy Modes and
32-bit Cortex-M3 and Cortex-M0 sub µA operation
reduce the spent time in active mode
8. Extremely energy efficient peripherals
• ADC: 12-bit, 1 Msps at only 350 µA
• Analog Comparator: using as little as 100 nA
3. Very fast wake-up time • LCD Controller: 8x36 segments at only 0.55 µA
Short 2 µs wake-up time supports • LEUART: Full UART @ 9600 bps using only 150 nA
high efficiency energy modes and • AES: 128/256-bit AES crypto-engine in only 54/75 cycles
increases responsiveness
9. AEM - Advanced Energy Monitoring
Measure and review your prototype´s current
consumption profile in real-time on our starter kits
4. Ultra-low standby current
Full RAM and CPU retention + 10. Simplicity Studio and energyAware software
POR + BOD + RTC while Fast design cycles, power profiling and energy de-
using only 0.9 µA (Energy Mode 2) bugging of application code to remove current drains
5. Autonomous peripheral operation
Applications can perform
advanced tasks without
using the Cortex CPU
