  • Energy Micro's EFM32 Gecko micro has demonstrated best CoreMark number based on the feature-rich ARM Cortex-M3 core.
  • EFMTG840F32 achieved a score of 15.4 CoreMark/mA using IAR Embedded Workbench for ARM version 6.40, over 20 percent more efficient in active mode than even the Cortex-M0+ devices.
  • Additionally, Gecko technology enables EFM32 MCU peripherals to communicate without using the CPU, further enabling the processor to remain in deep sleep for longer. The EFM32 wake up time is then just 2µs.
