The ARM® Cortexâ¢-M0 processor is the smallest, lowest-power and most energy-efficient ARM processor available. The exceptionally small silicon area, low power, and minimal code footprint of the processor achieves 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices. The Cortex-M0 processor promises substantial savings in system cost while retaining tool and binary compatibility with feature-rich processors such as the Cortex-M3 processor. It consumes as little as 85 µW/MHz (0.085 mW) in an area of typically under 12 K gates, enabling the creation of ultra low-power analog and mixed signal devices.
