Cortex® -M0 Versus Cortex-M0+ - KBA211306

Last Updated: February 29, 2016

What are the differences between Cortex®-M0 and Cortex-M0+?


The Cortex-M0+ processor builds on the Cortex-M0 processor, retaining the full instruction set and tool compatibility, while reducing energy consumption and increasing performance. 

The following table lists the difference in the features of the two processors.

Features M0 M0+ Advantages of M0+ over M0
Pipeline Three-stage Two-stage Improved response time,improved efficiency
Performance Efficiency 2.33 CoreMark/MHz 2.46 CoreMark/MHz Lower power and higher performance
Memory Protection Not available Has optional Memory protection Unit Makes system more secure by: Separating processes – Preventing tasks from corrupting stack or data memory used by other tasks Preventing unprivileged tasks from accessing peripherals that can be critical to the system security
Relocatable vectortable Does not support Supports Allows relocating the interrupt vector table anywhere in the memory - enables different applications to use their own vector table.
Unprivileged/privileged mode execution Does not support Supports Allows a task, such as the system calling in an operating system, to execute with more privileges than the user task or an application.


The PSoC 4-S Series family of devices has Cortex M0+ core, while the previous PSoC 4 families have Cortex-M0 core.
