Energy Micro Cortex-M4 MCU achieves performance benefits using low leakage process

Energy Micro has been working closely with TSMC to verify the benefits of using the TSMC eLL (Extreme Low Leakage) process to fabricate its next generation of energy efficient Cortex-M microcontrollers. By aligning closely with TSMC, Energy Micro has benefitted from early access to the process technology to further enhance its MCU portfolio.

TSMC’s eLL process is the latest refinement of its embedded Flash (EmbFlash) technology with even lower power consumption than its previous generation solution; 50-70% improved stand-by current and 30% better active current.

Commenting Andreas Koller, VP of Worldwide Sales at Energy Micro said, “Energy efficiency has set the EFM32 MCU products apart from our competitors. With a natural move to 32-bit DSP CPU cores like the ARM Cortex-M4 with FPU, our energy efficient Gecko Technology benefits from TSMC’s latest process enhancements with the best low energy performance.”

Maria Marced, President of TSMC Europe, said, “The use of TSMC’s extreme Low Leakage Embedded Flash process has resulted in significant power savings in Energy Micro’s products and further strengthened Energy Micro’s competitive position.”
