The Arm Cortex-M0+ processor is the most energy-efficient Arm processor available for constrained embedded applications.
The Cortex-M0+ processor builds on the very successful Cortex-M0 processor, retaining full instruction set and tool compatibility, while further reducing energy consumption and increasing performance.
The exceptionally small silicon area, low power and minimal code footprint of Cortex-M0+ enables developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices. The Cortex-M0+ processor comes with a wide selection of options to provide flexible development.

** The first result abides by all of the “ground rules” laid out in the Dhrystone documentation, the second permits inlining of functions, not just the permitted C string libraries, while the third additionally permits simultaneous (”multi-file”) compilation. All are with the original (K&R) v2.1 of Dhrystone.
***Minimum configuration with full ISA support and Interrupt Controller, includes 1 IRQ + NMI, excludes ETM, MPU and debug.
