# S32K344 MCU

The S32K344 is an Automotive General Purpose MCU of NXP Semiconductors. The block diagram of this chip is shown below. 

The software referred to in this GitBook is running on the Lockstep Arm Cortex-M7 embedded in this chip.

Note that there are many variants of the S32K3 family components. See the folowing links for more details: \

{% hint style="info" %}
The S32K344 is a **lockstep (dual) M7 part**. There is an almost identical S32K324 where the two cores are running independently. It would be possible for a user to swap chips on this EVK if this functionality is to be investigated..
