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