Detail about S32K338

[gianpiero_lenta]

Good morning,
I need to know if the S32K388 microcontroller has three independent cores, like the K324 (which has two), and if two of these cores can also be used in Lockstep.
If I want one single core + one Lockstep core, should I use the K358?

Thanks

Hello @gianpiero_lenta ,

Lockstep operation is not a software-configurable feature that can be enabled between two independent cores. Instead, Lockstep is a dedicated hardware configuration implemented in specific S32K3 derivatives.

Therefore, if your application requires one independent Cortex-M7 core together with a Lockstep Cortex-M7 pair, I recommend using the S32K358, which is designed with this hardware configuration.

Best regards,

Pavel
