I know it's probably an intentional exaggeration... but are there really any microcontrollers over 1 GHz core clock? Fast I know of is ST at around 600 MHz.

- gibibit 2y agoARM Cortex-A is an application processor, not a microcontroller. With an MMU (can run a full OS like Linux) and without internal memory. Cortex-M is a microcontroller, without MMU (can't run Linux etc.), and typically has internal RAM and flash. Only the NXP i.MXRT1170 reaches 1 GHz CPU clock, and this is not multi-GHz as the prior comment declared.
